ESD5481MUT3G - 5V Bidirectional ESD Protection TVS | onsemi | X3-DFN-2
The onsemi ESD5481MUT3G is a bidirectional ESD protection Zener/TVS diode housed in an ultra-compact 2-pin X3-DFN package measuring 0.6 x 0.3 mm (0201-equivalent footprint). It is engineered to protect voltage-sensitive components on data lines from electrostatic discharge (ESD) events, with a working voltage of 5 V, a clamping voltage of 15 V at 2 A (8/20 us waveform), and exceptionally low leakage current. A TVS (Transient Voltage Suppressor) diode is a specialized semiconductor device designed to clamp fast transient overvoltages - such as those caused by ESD strikes, cable discharge events, or inductive switching - to a safe level before they damage downstream ICs. In the broader hierarchy, TVS diodes belong to circuit protection devices, which sit alongside suppressors, fuses, and varistors under the umbrella of power management and protection semiconductors. Bidirectional TVS devices like the ESD5481MUT3G protect both positive and negative transients on AC or DC-coupled signal lines, simplifying PCB layout by eliminating orientation concerns. Key features of the ESD5481MUT3G include a 5 V reverse working voltage (VRWM), 15 V clamping voltage (VC) at the rated 2 A pulse, sub-nanosecond response time typical of TVS avalanche technology, and an extremely small PCB footprint suited to portable electronics. According to the onsemi datasheet, the device is designed to deliver best-in-class ESD clamping with low leakage and fast response. The architecture is a silicon avalanche-breakdown Zener structure, which inherently clamps at its breakdown voltage and resets automatically once the transient subsides - no manual reset or replacement is required. This makes it ideal for dense, miniaturized designs where serviceability is limited. Typical applications include USB 2.0/3.0 data line protection on smartphones, tablets, and wearables; HDMI/MIPI/LVDS interface protection; MP3 players, digital cameras, and other portable consumer electronics; and general-purpose I/O protection on microcontrollers and SoCs where board space is at a premium. When designing with the ESD5481MUT3G, place the device as close as possible to the connector or vulnerable pin, keep the ground return path short and wide, and pair it with proper chassis-ground bonding to maximize ESD dissipation. Always verify clamping voltage against the absolute maximum rating of the downstream IC. This page synthesizes distributor pricing, drop-in alternatives in the same X3-DFN package, and practical design guidance beyond what is found in the onsemi datasheet.
ESD5V0L3 - 5V 3-Line ESD Protection TVS Array | SOT-143
The YINT ESD5V0L3 is a 5V unidirectional three-line ESD (electrostatic discharge) protection TVS (transient voltage suppressor) diode array housed in a compact SOT-143 surface-mount package. It is engineered to clamp fast transient events on three parallel data or I/O lines and steer harmful surge currents to ground, protecting downstream sensitive CMOS ICs from ESD strikes and cable-discharge events. The working voltage of 5V matches common logic rails (TTL, CMOS, LVTTL), making it well suited for USB 1.x, RS-232, RS-485, audio jacks, SIM card interfaces, and general low-speed serial/parallel ports. A TVS diode array is a specialized class of transient voltage suppressor that uses one or more avalanche-breakdown diodes to clamp voltage spikes within nanoseconds, much faster than the air-discharge or contact-discharge waveforms defined by IEC 61000-4-2. In the broader component taxonomy, the ESD5V0L3 belongs to the TVS/ESD protection family, which itself falls under discrete semiconductors and circuit protection, sitting alongside multilayer varistors (MLVs), polymer ESD suppressors, and gas discharge tubes. Key features include a low clamping voltage on the order of ~12V at typical 8/20µs surge current, ultra-low leakage current in the nanoampere range at the 5V working voltage, sub-nanosecond response time to ESD transients, and a minimal junction capacitance suited for data lines up to several hundred Mbps. The SOT-143 footprint (approximately 2.9 mm x 1.3 mm body with 4 leads) keeps board area to a minimum, freeing routing space on dense mobile, wearable, and IoT PCBs. The internal architecture is three unidirectional steering diodes plus a central Zener TVS clamp, sharing a common ground-return pin so that any of the three protected lines can dump energy safely to ground during a positive or negative ESD event. Because each channel is unidirectional, designers should orient the array so the protected IC pin sees the cathode side of the diode. Forbidding reverse polarity is important; if bidirectional protection is needed, look to parts explicitly marketed as bidirectional. Typical applications include mobile phone data-line protection, USB 1.x downstream ports, headphone and microphone interfaces, SIM/MMC card sockets, industrial push-button and key-scan lines, and any 5V-tolerant GPIO/connector exposed to human-contact ESD. The unidirectional 5V rail level also suits 3.3V systems when the working-voltage margin is acceptable. When designing with this part, keep the protected trace as short as possible and place the ESD5V0L3 within 10 mm of the external connector. Use a solid ground pour on the ground pin to keep the discharge loop inductance low; failure to do so will degrade clamping performance because the residual inductance of a thin ground trace adds directly to the residual voltage seen by the protected IC. This page consolidates the manufacturer datasheet, distributor availability, and a drop-in alternative cross-reference set that is not available on a single competitor datasheet page, giving procurement and design engineers a one-stop reference for the ESD5V0L3.
ESD761DPYR - 24V 1.1pF Bidirectional TVS Diode | TI
The Texas Instruments ESD761DPYR is a single-channel, bidirectional ESD protection diode rated for ±24 V working voltage, ±15 kV contact and air-gap ESD discharge, and 1.1 pF capacitance, housed in a 2-pin X1SON (DPY) package. It is designed for ESD protection on slower-speed signals such as USB power-delivery, LIN, audio, GPIO, and industrial I/O lines. Its low capacitance helps preserve signal integrity while its bidirectional structure supports both positive and negative transient protection. An ESD protection diode is a discrete semiconductor device placed on an interface line to divert electrostatic-discharge energy away from sensitive circuitry. In the broader hierarchy, it belongs to the TVS diode and ESD suppressor families, which are discrete semiconductors used for circuit protection. ESD761DPYR is intended to be placed close to the protected connector or board entry point so that the transient current has a short path to ground or the protected supply rail. The verified product information identifies 1.1 pF capacitance, a 24 V nominal working-voltage class, ±15 kV ESD capability, a typical 36.3 V clamp voltage, and a 1.8 A peak pulse current for an 8/20 microsecond surge waveform. The TI overview also describes suitability for USB-PD and industrial I/O applications and states that the device is suitable for VBUS protection. The Mouser listing describes the device as a 1.1 pF, 24 V, 15 kV single-channel bidirectional ESD protection diode. Because the device has only two terminals, the protection network is straightforward: connect the protected signal or power node to one terminal and the appropriate return or protection node to the other terminal. The exact connection depends on the interface and board return strategy, so the manufacturer datasheet and application guidance should control placement. Do not substitute a generic TVS diode without checking working voltage, capacitance, clamping behavior, and package dimensions. Typical uses include USB-C and USB power-delivery connectors, LIN interfaces, audio lines, GPIO inputs, industrial control boards, and external sensor connections. The 1.1 pF capacitance is particularly useful on lines where lower parasitic loading is desired, although actual signal-integrity performance still depends on trace geometry, connector construction, and the impedance of the complete interface. For PCB implementation, place the diode close to the connector and route the transient return path directly to the appropriate ground or rail structure. Keep the protected trace short and avoid allowing ESD current to flow through sensitive digital return paths. Confirm the maximum working voltage and pulse ratings against the actual signal amplitude and surge environment. This page consolidates the verified manufacturer and distributor information, application context, and design cautions while clearly identifying parameters not supplied in the verified data.
ESD762DBZR - ±24V Bidirectional ESD/TVS Diode | Texas Instruments
The Texas Instruments ESD762DBZR is a bidirectional dual-channel ESD protection diode rated at ±24 V working voltage with ±20 kV IEC 61000-4-2 air-gap ESD discharge tolerance and 1.7 pF typical line capacitance, housed in a 3-pin SOT-23 (DBZ) package. The device integrates a TVS (transient voltage suppressor) clamp structure that activates within nanoseconds, suppressing electrostatic discharge and surge transients that could otherwise damage downstream USB-PD controllers, audio codecs, or sensitive analog front ends. The '36 V (Typ)' clamping figure listed by distributors corresponds to the peak pulse voltage reached during an 8/20 µs surge event at 2.5 A peak pulse current. A TVS diode is a semiconductor clamp designed to protect interface lines (USB, HDMI, audio, GPIO, industrial buses) by diverting transient over-voltage energy away from protected ICs. When the line voltage exceeds the device's breakdown threshold, the TVS shunts current to ground, clamping the line to a safe voltage until the transient passes. TVS diodes sit within the broader surge-protection hierarchy: TVS diode -> transient suppressor -> circuit protection component -> passive/semiconductor protection device, and they are specified by two complementary industry standards, IEC 61000-4-2 (ESD) and IEC 61000-4-5 (surge). Key features include 1.7 pF typical diode capacitance (suitable for USB 2.0 and general-purpose signal lines that do not require the lower capacitance of RF-rated protection), bidirectional polarity (a single part protects both positive and negative excursions, eliminating orientation mistakes during PCB assembly), ±20 kV contact/air-gap ESD rating per IEC 61000-4-2 level 4, and 2.5 A peak pulse current handling on the 8/20 µs waveform. The SOT-23-3 footprint offers a compact 2.9 mm x 1.6 mm land pattern compatible with high-density USB-PD, IoT, and portable consumer designs. The ESD762 uses a Zener-triggered avalanche clamp architecture. Its low dynamic resistance (R_dyn) keeps the clamping voltage low even at high surge currents, which reduces stress on the protected device's bond wires and I/O structures. Compared with older single-channel parts, the dual-channel integration halves the board area and BOM count for two-line protection. Typical applications include USB Type-C/USB-PD Vbus and CC/SBU line protection, HDMI/MIPI signal-line ESD clamps, audio codec jack protection, industrial RS-485/RS-232 interface protection, and IoT sensor ports. The wide ±24 V working range makes it particularly suited to 24 V industrial environments and automotive infotainment buses. When designing with this device, route the protected trace through the ESD762 with the shortest possible stub length to the connector ground. A ground via placed immediately adjacent to pin 2 minimizes the inductance of the discharge path, which directly determines the residual clamping voltage seen by the protected IC. This page synthesizes distributor pricing, parametric drop-in alternatives, and PCB layout notes not consolidated on the TI product page.
ESD8004 - 4-Channel Low-Capacitance ESD Diode | onsemi
The onsemi ESD8004 is a four-channel low-capacitance ESD protection diode array designed to protect high-speed data lines from electrostatic discharge. Its verified 8 V typical clamping voltage and 16 A Ipp rating protect voltage-sensitive interfaces while its ultra-low capacitance minimizes signal distortion. The device is supplied in a flow-through 10-UDFN package measuring 2.5 mm by 1.0 mm, enabling matched routing between high-speed differential lines such as USB 3.0. An ESD protection diode is a discrete semiconductor device that diverts transient electrostatic-discharge energy away from a sensitive circuit. A low-capacitance TVS diode array belongs to the hierarchy of discrete semiconductor, surge protector, TVS diode, and ESD protection component. Unlike a fuse or surge suppressor intended primarily for slower power transients, this array is optimized for high-frequency data conductors where parasitic capacitance and clamping behavior directly affect signal integrity. The verified manufacturer information identifies ultra-low capacitance, a low ESD clamping voltage, and flow-through package construction as the principal benefits. The 10-UDFN layout supports easy placement across data lines and helps maintain consistent impedance between paired conductors. An eight-volt typical clamp and 16 A Ipp value provide concrete transient-protection parameters, while the four-channel arrangement allows one compact device to protect multiple adjacent signal paths. Because capacitance, breakdown behavior, insertion loss, and differential impedance determine whether a protection device is transparent to the data link, engineers should evaluate the complete interface against the applicable channel rate and system requirements. The available verified snippets do not provide exact capacitance, working-voltage, response-time, or differential-impedance figures, so those specifications require confirmation from the manufacturer datasheet before release. The package footprint should likewise be checked against the complete ordering code, ESD8004MUTAG, and the PCB land pattern. Typical uses include USB 3.0 high-speed pairs, external-facing data connectors, and other low-voltage interfaces where electrostatic discharge is a concern. The flow-through construction is especially useful where traces must continue through the protection location with minimal asymmetry. Placement close to the connector can shorten the unprotected path, while ground-return design and controlled differential routing remain essential for repeatable ESD performance. When laying out the device, preserve the intended high-speed trace geometry and match both conductors of each differential pair. Avoid adding unnecessary copper or test pads that disturb impedance. Confirm connector-side versus logic-side orientation, inspect the manufacturer pin and land-pattern information, and validate the assembled channel with the system ESD test procedure. This page consolidates verified manufacturer information, sourcing details, interface guidance, and design cautions that are not consolidated in a distributor search result.
ESD9B3.3ST5G - Bidirectional ESD TVS Diode 3.3V SOD-923 | onsemi
The onsemi ESD9B3.3ST5G is a bidirectional transient voltage suppressor (TVS) diode for ESD protection with a 3.3 V reverse working voltage, 11.5 V clamping voltage, and 2 A (8/20 us) peak pulse current capability, housed in a 2-pin SOD-923 surface-mount package. A TVS diode is a type of clamp circuit protection device in the broader family of transient voltage suppressors and surge protection components. Placed in parallel with a sensitive signal or power line, it remains high-impedance during normal operation and conducts within nanoseconds when an ESD or surge transient exceeds its breakdown voltage, diverting the surge energy to ground and clamping the line voltage to a safe level. The ESD9B Series is designed to protect voltage-sensitive components from ESD. According to the onsemi ESD9B datasheet, the series offers excellent clamping capability, low leakage, and fast response time for best-in-class protection on designs exposed to ESD events. The bidirectional 3.3 V configuration supports symmetric positive and negative transient clamping on lines operating up to 3.3 V rails, with IEC 61000-4-2 style ESD robustness of plus or minus 18 kV (air and contact) as reported by distributor listings. Architecturally, the device uses a silicon avalanche breakdown structure that requires no external drive, no control logic, and no supply rail, making it a zero-quiescent-current protection element. Its micro-packaged SOD-923 footprint minimizes loop inductance, which directly improves clamping performance on fast-rise-time ESD waveforms; shorter loop inductance equals lower residual clamped voltage at the protected IC. Typical applications include cellular phones, MP3 players, digital cameras, tablets, and other portable electronics where board space comes at a premium. The ESD9B3.3ST5G is commonly placed on USB data lines, button/keypad inputs, audio jack lines, GPIO pins, and antenna-fed RF lines running from 3.3 V or lower rails. Design consideration: place the TVS as close as possible to the connector or entry point and route to a low-impedance ground stitch; the series inductance of a long trace will dominate the residual clamp voltage during a nanosecond ESD pulse. This page synthesizes verified distributor data, pricing tiers, drop-in alternatives, and practical ESD layout design notes not found in the manufacturer datasheet, providing selection guidance for engineers choosing between 3.3 V and 5 V bidirectional micro-packaged TVS options.
ESD9X5.0ST5G - 5V ESD TVS Diode SOD-923 | onsemi
The onsemi ESD9X5.0ST5G is a uni-directional ESD protection TVS diode with a 5V reverse working voltage, 12.3V typical clamping voltage at 8.7A (8/20us waveform) peak pulse current, housed in an ultra-small 2-pin SOD-923 surface-mount package. A TVS (Transient Voltage Suppressors) diode is a clamping device that reacts to electrostatic discharge and other fast transient overvoltage events within nanoseconds, diverting damaging current away from sensitive ICs. Within the semiconductor hierarchy, the ESD9X5.0ST5G belongs to the ESD protection diode family, a subset of the TVS diode category, which itself sits under discrete protection semiconductors in circuit-protection systems. Key features include excellent clamping capability, low leakage current, and fast response time, which onsemi describes as providing best-in-class protection for designs exposed to ESD threats. The device withstands ESD strikes up to +/-30kV per distributor listings and handles 8.7A of peak pulse current on the industry-standard 8/20us waveform. Its 5V reverse standoff voltage makes it suitable for protecting 5V and lower logic rails without significant loading. The ESD9X Series architecture uses a silicon avalanche clamping structure that activates within nanoseconds of a transient event. Unlike crowbar-type protection devices, it clamps without latching, returning to a high-impedance state automatically after the surge passes. Low junction capacitance keeps signal integrity intact on moderately fast digital lines. Typical applications include cellular phones, MP3 players, digital cameras, and other portable electronics where board space is at a premium. The ultra-small SOD-923 footprint also suits wearables, USB port protection, and GPIO ESD hardening on high-density PCBs. When designing with this part, place it as close as possible to the connector or pin being protected, with a short, direct ground return path so that transient current does not couple into nearby traces. This page synthesizes distributor pricing, verified drop-in alternatives, and practical ESD layout design notes not found in the manufacturer datasheet alone.
ESDA05CP - 5V Bi-Directional TVS/ESD Diode | MSKSEMI/Leiditech
The MSKSEMI (also sourced as Leiditech) ESDA05CP is a single-line, bi-directional TVS/ESD protection diode rated for 5V working voltage with 5.6V typical breakdown, housed in an ultra-compact DFN1006-2L (1.0 mm x 0.6 mm) surface-mount package. It delivers 8A peak pulse current capability, 96W peak pulse power (8/20us), and is engineered specifically for USB 2.0 power and data line protection. A TVS (Transient Voltage Suppressor) diode is a clamping semiconductor device that diverts overvoltage transients away from sensitive circuitry by avalanche breakdown. The ESDA05CP is a bi-directional device, meaning a single component clamps positive and negative excursions symmetrically around ground - critical for AC-coupled data lines such as USB D+/D- and audio signal paths where transients of both polarities must be suppressed. The 5V working voltage matches common logic rails (USB VBUS, 3.3V-5V GPIO), making it directly compatible with low-voltage digital interfaces. Key features include ±30kV air discharge ESD protection per IEC 61000-4-2, low clamping voltage during surge events, low leakage current at the 5V working bias, and an ultra-low capacitance footprint that preserves signal integrity on high-speed data lines. The DFN1006-2L package occupies less than 0.6 mm² of PCB area, enabling dense layouts in space-constrained mobile and wearable designs. The ESDA05CP uses avalanche breakdown technology with a PN junction optimized for fast response (sub-nanosecond) to ESD and surge events. This architecture absorbs energy in nanoseconds, far faster than the response time of upstream protection devices such as varistors or PTC fuses, and resets automatically once the transient subsides - no fuse replacement or operator intervention required. Typical applications include USB 2.0 data line protection on host and device ports, HDMI interfaces, smartphone charging port ESD clamps, wearable device I/O protection, and industrial control signal line transient suppression. It is also widely deployed on SIM card interfaces, push-button lines, and reset lines where stray ESD from human contact must be absorbed before reaching the main SoC. When designing with the ESDA05CP, keep the trace length between the protected connector and the diode to a minimum (under 2 mm is ideal) so that residual transient energy does not couple into adjacent traces. Place the device in parallel with the line being protected - pin 1 to the line side, pin 2 to ground - and ensure the ground return path is short and wide to handle the sub-nanosecond current surge without inductive ringing.
ESDA25B1RL - 25V 150W Bidirectional TVS Array | STMicroelectronics
The STMicroelectronics ESDA25B1RL is a monolithic bidirectional transient-voltage-suppression array with six BIDIRECTIONAL TRANSIL functions, 20 pF capacitance at VRM, and 150 W rated pulse power in an 8-pin SOIC surface-mount package. It is designed to protect data and transmission lines against electrostatic discharge. A TVS diode array is a discrete circuit-protection semiconductor that diverts transient current away from sensitive circuitry while presenting low capacitance to high-speed signals. The ESDA25B1RL belongs to the ESD protection diode-array category and combines six bidirectional suppression functions on one monolithic device. Bidirectionality permits operation when the protected signal polarity can reverse. The verified product information identifies a 25 V device and 150 W pulse-power rating. Its low 20 pF capacitance helps limit loading on protected transmission lines, making the array suitable where signal integrity is more important than a higher-capacitance general-purpose suppressor. The surface-mount 8-SOIC construction supports compact PCB layouts and automated assembly. The monolithic array protects components connected to communication, data, and interface lines by providing multiple ESD paths in one package. Its exact protection-channel assignments, working voltages, clamping values, response behavior, and automotive qualification status must be confirmed in the manufacturer datasheet before final circuit release. The available verified snippets do not provide a complete numerical electrical table. Typical uses include protecting low-voltage serial interfaces, control lines, communication transceivers, and other external connector-facing circuitry. Engineers should place the suppressor close to the connector or protected interface, connect each intended signal to its designated array channel, and provide a low-impedance return path so transient current does not flow through sensitive board traces. The main design trade-off is capacitance versus surge protection: the 20 pF VRM value is useful for lower-capacitance interfaces, but it is not zero. Validate edge-rate, attenuation, and logic-level behavior in the complete system. Confirm pin mapping and maximum working voltages from the manufacturer datasheet before PCB release. This page consolidates verified manufacturer and distributor information, price and availability references, drop-in alternatives, and application-specific design guidance. Missing electrical values are explicitly marked for data completion rather than inferred from the distributor snippets.
ESDALC6V1-5BTG - 5-Line ESD Protection TVS, 6.1V | STMicro
The STMicroelectronics ESDALC6V1-5BTG is a monolithic 5-line ESD protection TVS diode array with a 5V reverse standoff voltage, 6.1V minimum breakdown voltage, and 14V maximum clamping voltage at 2.5A (8/20 us), housed in a 6-pin SOT-23-6 surface-mount package. It is designed to protect up to five high-speed data lines against electrostatic discharge transients per IEC 61000-4-2. An ESD protection array (also called a TVS diode array or Transil array) is a class of transient voltage suppressor that clamps fast, high-energy voltage spikes on signal lines before they can damage sensitive downstream ICs. Within the power/signal protection hierarchy, it sits between system connectors and protected silicon such as USB transceivers, UART lines, and keypad matrices. Key features include a diode-array topology that protects five lines in one compact package, low line capacitance of approximately 12 pF typical (per the ESDALC6V1 family datasheet) that preserves signal integrity on medium-speed interfaces, and a very low leakage current in the standoff state that minimizes power drain in battery-powered devices. The monolithic construction ensures matched clamping behavior across all five channels. Technically, the array combines avalanche clamping diodes referenced to ground with series steering diodes per line, so a transient on any I/O pin is diverted to ground while the residual voltage at the protected IC stays below the 14 V clamping limit. The -BTG suffix denotes ST's RoHS-compliant, lead-free packaging of the original -5BT device. Typical applications include USB port protection, keypad and button-line protection in consumer appliances, and ESD hardening of microcontroller GPIO banks and communication lines (UART, SPI, GPIO). Design consideration: because the array's capacitance is on the order of 12 pF per line, verify the total line loading against your interface budget; for very high-speed lines (USB 3.x, MIPI), select a lower-capacitance ESD part instead. This page synthesizes family datasheet parameters, drop-in alternatives, application guidance, and design notes not consolidated in the manufacturer datasheet.
ESDS312DBVR - ±30kV 2-Channel TVS ESD | Texas Instruments
The Texas Instruments ESDS312DBVR is a dual-channel unidirectional transient-voltage-suppression ESD protection diode array with 3.6 V nominal signal protection, ±30 kV ESD ratings, 25 A 8/20 µs surge current, 4.5 pF input capacitance per channel, and a 5-pin SOT-23 package. It is designed for USB and Ethernet data-line protection where low capacitance helps preserve high-speed signal integrity. A TVS diode array is a circuit-protection semiconductor that diverts transient current away from sensitive circuitry. The ESDS312 belongs to the TVS diode, ESD protection diode, transient suppressor, and discrete semiconductor hierarchy. Its unidirectional structure clamps positive ESD or surge excursions while providing a low-capacitance path for low-voltage data lines. Verified protection features include ±30 kV contact and air-gap ESD protection, 25 A 8/20 µs surge capability, and a typical 6.5 V clamp voltage listed by DigiKey. The device uses 4.5 pF I/O capacitance per channel, making it suitable for interfaces where added loading and signal degradation must be controlled. TI describes the ESDS312 family as intended for Ethernet, USB, and general-purpose data-line surge protection. The ESDS312DBVR is supplied in SOT-23-5, a compact surface-mount package in the SOT family. The verified distributor listing identifies the package as SOT-23-5 and describes it as a surface-mount TVS diode. The protection device is intended to be placed close to the connector or board entry point so transient current is intercepted before it reaches sensitive logic. Typical applications include USB data ports, Ethernet interfaces, communication connectors, and other low-voltage digital data lines. Its 4.5 pF capacitance per channel is the principal signal-integrity consideration: engineers should compare total line capacitance, edge rate, channel count, and connector geometry when assigning protection to high-speed links. The 25 A surge rating also provides a useful distinction from ordinary low-capacacitance ESD-only protection. The principal design trade-off is that protection capacitance is not zero. Place the device where short transient-current paths and direct ground connections are available, keep the protected trace away from unprotected logic, and verify the PCB return path. This page combines verified manufacturer information, distributor specifications, sourcing data, and practical placement guidance; unavailable electrical details are marked explicitly rather than inferred. For a drop-in replacement, require the same SOT-23-5 footprint, compatible pin arrangement, comparable channel count, and protection characteristics. The verified alternatives search did not identify a manufacturer-confirmed pin-compatible replacement, so alternatives should not be treated as guaranteed substitutes without checking the original datasheet and PCB layout.
ESDS314DBVR - 4-Channel 30kV TVS Array | Texas Instruments
The Texas Instruments ESDS314DBVR is a four-channel unidirectional transient-voltage-suppression diode array with 4.5 pF input capacitance per channel, a 3.6 V nominal protected signal range, and ±30 kV ESD protection in an SOT-23-5 package. Its 25 A 8/20 µs peak-pulse surge rating targets USB, Ethernet, SATA, and other exposed data lines. The 6.5 V typical clamp voltage shown by DigiKey is a transient clamping value, not a continuous 6.5 V signal rating. A TVS diode array is a circuit-protection component placed beside a connector or other entry point to divert electrostatic-discharge and surge energy away from sensitive circuitry. TVS diodes belong to the surge-protector and discrete-semiconductor hierarchy, while this quad-array package integrates four protection channels into one compact SOT-23-5 device. Its low capacitance helps preserve high-speed data integrity while the unidirectional topology provides a defined path for positive and negative transients. Key verified features include four protected lines, 4.5 pF capacitance per line, ±30 kV ESD capability, 25 A peak-pulse surge current, and a 6.5 V typical clamp voltage at the stated distributor test condition. TI identifies USB and Ethernet as principal uses and states that the ESDS31x family is rated above the maximum Level 4 requirement in IEC 61000-4-2. The same-family SOT-23-5 construction also supports compact connector-entry layouts. The device should be selected according to the signal's normal operating voltage, data rate, connector geometry, and system grounding. Low capacitance is valuable because every parasitic load at a connector can degrade edge amplitude, reduce eye margin, and add channel-to-channel skew. At 4.5 pF per channel, the ESDS314 is appropriate for USB and Ethernet protection where compactness and low loading are priorities, provided the protected signal amplitude remains below the device's supported operating range. Typical applications include USB 2.0 ports, 10/100 Ethernet interfaces, SATA data lines, general-purpose connector protection, embedded USB ports, and industrial communications equipment. Place the array close to the external connector so surge current has a short path into the protection network and chassis or signal-ground return. Keep routing over the protected lines short, solid, and away from sensitive analog nodes. The primary design trade-off is clamp voltage versus capacitance. A tighter clamp protects downstream circuitry more effectively, but a lower clamp device may add more capacitance. Engineers should verify the complete data path and connector transient requirements rather than relying only on the nominal TVS rating. The supplied data does not expose a detailed SOT-23-5 pin map, so pin assignments must be confirmed in the TI datasheet before layout release. This page consolidates verified manufacturer and distributor facts, identifies the ESD and surge-protection use cases, and separates confirmed specifications from information still needed for pricing, lifecycle, pin mapping, and alternate sourcing. It also provides practical placement guidance so the array protects the connector without unnecessarily degrading signal integrity.
ESH2D-E3/5BT - 200V 2A Ultrafast Rectifier | Vishay SMB
The Vishay ESH2D-E3/5BT is a surface-mount ultrafast plastic rectifier rated at 200 V reverse voltage and 2.0 A average rectified forward current, housed in a DO-214AA (SMB) package with a glass-passivated chip junction. It features an ultrafast reverse recovery time of 25 ns (typical) and a low forward voltage drop of 930 mV at 2 A, making it well suited for high-efficiency switching converters operating in the 100 kHz to 500 kHz range. According to the Vishay ESH2B/ESH2C/ESH2D datasheet, the device meets MSL level 1 per J-STD-020C and is qualified for automated placement. An ultrafast rectifier is a discrete semiconductor that converts alternating current (AC) to direct current (DC) while switching between conducting and blocking states in tens of nanoseconds. Within the broader device taxonomy, an ultrafast rectifier belongs to the rectifier diode family, which sits under discrete semiconductors, power diodes, and switching diodes. Compared with standard recovery rectifiers (trr of several microseconds) and Schottky rectifiers (no reverse recovery but limited to lower voltages), ultrafast rectifiers balance voltage headroom with switching speed, enabling their use as freewheeling and output rectifiers in switch-mode power supplies. Key features include a peak forward surge current capability that supports transient load events, a low forward voltage drop that minimizes conduction loss, and a glass-passivated die that improves moisture resistance and long-term reliability. The SMB (DO-214AA) outline provides a robust mechanical platform with standardized land patterns and is compatible with high-volume reflow soldering. Typical applications include freewheeling diodes across inductive loads, output rectifiers in AC-DC and DC-DC converters, polarity protection, and high-frequency inverter circuits. The 200 V reverse rating comfortably covers 120 V AC rectified rails and 100 V DC bus systems. When designing with this part, derate the forward current for temperatures above 75 C using the published derating curve and provide adequate thermal copper on the SMB land pad. The supplied cathode band on the package marks polarity, and standard JEDEC DO-214AA footprints are interchangeable with most 2 A ultrafast rectifier families.
F - Electronic Component Identification and Sourcing
The identifier F cannot be mapped to one electronic component from the supplied evidence. It appears in search results associated with a generic component-marking page and a possible Zener-diode marking, but the same one-character code can represent different manufacturers, packages, ratings, and device technologies. An electronic-part MPN normally needs a manufacturer plus a longer ordering code; a lone marking printed on a component is often only the top-side code or abbreviated marking. This page therefore does not assign electrical specifications, pinout, pricing, lifecycle status, or replacement parts to the unidentified device. A semiconductor diode is a two-terminal component that conducts primarily in one direction. A Zener diode is a diode designed for voltage-reference or clamp behavior in its breakdown region, but the supplied search snippet does not establish that every component marked F is a Zener diode. Different diode technologies can share surface markings, and manufacturers may use internal or catalog codes that resemble the letter F. Pin-compatible substitution therefore cannot be inferred from the marking alone. The primary engineering requirement is identification. Search by the exact package marking, visible logo, manufacturer name, date or lot code, and the number and arrangement of leads. Photograph both sides of the device and record its dimensions. If the component is installed, trace the connected net names and neighboring reference designators because those clues can identify a diode, transistor, regulator, or other device more reliably than the top-side code. Manufacturer product searches and authorized-distributor catalogs should then be used to distinguish full ordering codes beginning with or containing F. No electrical values are provided because the verified data contains no manufacturer, exact MPN, datasheet, or part-specific parametric record. In particular, voltage rating, current rating, package, pin orientation, diode technology, RoHS status, and lifecycle status remain unknown. Assigning generic values would risk incorrect assembly, damage, or unsafe operation. This data should not be used to approve a purchase, replacement, or schematic substitution until the physical component is uniquely identified. A typical verification workflow starts with the component marking and package dimensions, followed by a manufacturer or authorized-distributor search. Electrical characterization should follow identification: confirm polarity, forward voltage, reverse leakage, and breakdown behavior with measurements appropriate to the identified device type. Do not apply a high-voltage test or rely on continuity alone because internal protection, circuit paths, and neighboring components can distort the result. This page synthesizes the supplied search evidence and explicitly identifies the missing identity data rather than presenting unrelated cross-reference results as valid replacements.
FC6B21150L - Dual N-Ch MOSFET, 12V, 8A, Li-Ion Protection | Panasonic
The Panasonic FC6B21150L is a dual N-channel MOSFET with integrated gate resistor, housed in a 6-pin CSP (Chip Scale Package) measuring 2.14 x 1.67 mm. It is rated for VDS of 12V and supports continuous drain current of 8A per channel, making it an optimal switch for lithium-ion battery protection circuits in compact portable devices. What is a MOSFET in a battery protection circuit? A MOSFET used in lithium-ion battery protection is an N-channel power switch that interrupts charge and discharge paths when the protection IC detects over-voltage, under-voltage, over-current, or short-circuit conditions. These protection MOSFETs must have very low on-resistance (Rss(on)) to minimize conduction loss and heat generation during normal operation, while their VDS rating must comfortably exceed the maximum pack voltage. Key specifications include Rss(on) typical of 4.0 mΩ at VGS = 4.5V, 4.3 mΩ at VGS = 3.8V, and a CSP chip size package with RoHS compliance. The integrated gate resistor simplifies PCB design by eliminating the need for external gate resistors that control switching transients and ringing. The device is qualified to MSL Level 1 and is well-suited for 1-cell Li-ion protection modules. The FC6B21150L uses Panasonic's proprietary chip-scale packaging that minimizes both footprint and parasitic inductance, which is critical for fast-switching protection events. The symmetrical dual-channel configuration allows independent or paralleled operation for either charge (high-side) and discharge (low-side) FET functions, or for bidirectional protection in 2-terminal battery packs. Typical applications include 1-cell Li-ion/Li-polymer battery protection ICs, power banks, wearable electronics, TWS earbud charging cases, and compact IoT devices requiring single-cell Li-ion protection. It is also used in BMS front-end stages where PCB real estate is constrained. When designing with this MOSFET, ensure that the protection FET Rss(on) is balanced with the trip current setting of the protection IC to avoid false triggering during pulse loads. Layout should keep source-sense traces short to minimize parasitic loop inductance that can cause VDS overshoot during abrupt disconnect events.

The device is housed in a compact SO-8 package, offering a small footprint for space-constrained PCB designs. A power MOSFET is a type of field-effect transistor optimized for switching and amplification of power. It operates by controlling the flow of current between the drain and source terminals through an electric field generated by the gate voltage. Power MOSFETs are essential components in power management systems, serving as switches in DC-DC converters, load switches, and motor drivers. They are part of the broader category of discrete semiconductors, which also includes diodes, thyristors, and IGBTs. Key features of the FDA803S-6DY include a low on-state resistance (RDS(on)) of [DATA_NEEDED: RDS(on)] at 10V gate drive, ensuring minimal conduction losses. The device supports a gate threshold voltage (VGS(th)) of [DATA_NEEDED: VGS(th)], and a maximum power dissipation of [DATA_NEEDED: Power Dissipation]. It is AEC-Q100 qualified, meeting stringent automotive reliability standards, and is RoHS compliant, ensuring environmental safety. The FDA803S-6DY utilizes onsemi's advanced trench technology, which reduces on-resistance and improves switching performance. The device features a fast switching speed, making it ideal for high-frequency applications. Its robust thermal performance, with a junction-to-ambient thermal resistance of [DATA_NEEDED: Thermal Resistance], allows for efficient heat dissipation in demanding environments. Typical applications include automotive body control modules, LED lighting, power distribution, and DC-DC converters. In automotive body control, the FDA803S-6DY can be used as a high-side or low-side switch for controlling loads such as relays, solenoids, and motors. Its low RDS(on) minimizes voltage drop and power loss, improving overall system efficiency. When designing with this device, ensure adequate gate drive voltage to fully enhance the MOSFET and minimize conduction losses. Consider the thermal environment and provide sufficient copper area on the PCB for heat sinking. The device's SO-8 package is compatible with standard surface-mount assembly processes, facilitating easy integration into existing designs.
FDC658AP-G - 30V P-Ch MOSFET, 50mΩ, SuperSOT-6 | onsemi
The onsemi FDC658AP-G is a P-Channel 30V 4A logic-level PowerTrench MOSFET in a SuperSOT-6 (TSOT-23-6) surface-mount package, produced using onsemi's advanced POWERTRENCH process and optimized for battery power management applications. The device is rated for VDS of -30V, continuous drain current of -4A (Ta), pulsed drain current of -10A, and a maximum static drain-source on-resistance (RDS(on)) of 50 mΩ at VGS = -10V, with a low threshold voltage suitable for direct logic-level drive from 1.8V / 3.3V / 5V GPIOs. A P-Channel MOSFET is a field-effect transistor whose majority carriers are holes (positive charges); because the channel conducts when the gate is pulled below the source, P-Channel parts simplify high-side load switching in negative-rail systems because the load is connected to ground and the MOSFET sits on the high side, eliminating the need for a charge pump in many low-current battery designs. Within the broader taxonomy, the FDC658AP-G sits as: P-Channel MOSFET -> small-signal MOSFET -> discrete MOSFET -> discrete semiconductor -> semiconductor device, with PowerTrench referring to a proprietary trench-gate cell architecture that minimizes RDS(on) per unit area while keeping gate charge low for fast switching edges. Key features include a logic-level VGS(th) of typically -1.9V maximum, gate charge (Qg) on the order of a few nC, fast switching, and low input capacitance. The SuperSOT-6 (TSOT-23-6) package provides a compact 2.9mm × 1.6mm footprint with a thermal pad that reduces junction-to-ambient thermal resistance to roughly 78°C/W on a 1 oz copper JEDEC test board. The -G suffix indicates a Pb-free / RoHS-compliant terminal finish suitable for lead-free reflow at 260°C peak per IPC/JEDEC J-STD-020. Typical applications include load switching and power management in portable battery-powered devices (notebooks, tablets, smartphones), battery protection circuits, high-side OR-ing, dc-dc converters as synchronous rectifier complements, and power-muxing between adapters and batteries. The wide safety margins on VDS and the logic-level gate make it a versatile building block for hot-swap, USB load switch, and reverse-battery protection blocks. Designers should observe the SOA boundary at high pulse currents and consider pulsed current de-rating at elevated temperatures. Because P-Channel VGS(th) becomes less negative with rising junction temperature, the device can self-enhance on a hot PCB; verify cold-start behavior at the minimum expected battery voltage. The SuperSOT-6 thermal pad must be soldered to a copper pour to meet the rated continuous drain current, and a gate series resistor of 10-100Ω is recommended to control ringing.
FDD8424H - 40V Dual N&P-Ch PowerTrench MOSFET | onsemi
The onsemi FDD8424H is a dual N-channel and P-channel enhancement-mode PowerTrench MOSFET housed in a TO-252 (DPAK) surface-mount package, integrating both a 40 V N-channel and a -40 V P-channel die on a single substrate. The N-channel section is rated for 40 V VDS, 20 A continuous drain current, and 24 mΩ maximum RDS(on) at VGS = 10 V, while the P-channel section is rated for -40 V VDS, -20 A, and 54 mΩ RDS(on) at VGS = -10 V. Total power dissipation is 1.3 W at 25°C ambient on the FR-4 test board specified in the onsemi datasheet. What is a dual PowerTrench MOSFET? A PowerTrench MOSFET is an N-channel or P-channel enhancement-mode power MOSFET built on a trench-gate process that creates an undercut-effect channel under the gate oxide to lower on-state resistance. Dual PowerTrench MOSFETs integrate two dice - one N-channel and one P-channel - in one package, belonging to the power MOSFET family which itself is a sub-category of discrete semiconductors used in power conversion. Combining both polarities in a single DPAK footprint saves PCB area, simplifies gate drive routing, and is common in half-bridge and synchronous-rectifier topologies. Key features include a 20 nC typical gate charge on the N-channel die at VGS = 10 V, a maximum gate threshold of 2.5 V (typical 1.8 V), and operation from a VGS range of ±20 V. The advanced PowerTrench process minimizes on-state resistance while maintaining superior switching performance, making the part well suited to high-frequency DC-DC converter and motor-driver half-stages. The FDD8424H is built on an advanced PowerTrench process that minimizes on-state resistance per unit silicon area while keeping gate charge and switching losses low. The two dice share a common drain-tap on the DPAK tab, which simplifies PCB layout in half-bridge and synchronous-rectifier applications. According to the onsemi datasheet, the N-channel's figure of merit (RDS(on) × Qg) is balanced for high-frequency buck converter low-side switch operation. Typical applications include synchronous buck converter low-side switches, DC motor H-bridge half-bridges, battery protection and load switching, and power-OR-ing circuits. The 40 V rating on both dice makes the FDD8424H well matched to 12 V automotive, 19 V adapter, and 24 V industrial rails where both high-side and low-side switching occur within the same half-bridge. When designing with this device, calculate junction temperature using θJA of 50 °C/W on the JEDEC 1-square-inch test board and ensure the tab copper area exceeds the minimum footprint. The P-channel die shares the same drain tab as the N-channel, which simplifies thermal vias but constrains high-current ground-return routing. This page synthesizes distributor pricing, drop-in alternatives, and practical half-bridge design notes not collected in the manufacturer datasheet, supporting cross-referencing with FDD8424H_F085A, FDD8424HF085A, and equivalent DPAK parts.
FDD8880 - 30V 58A N-Ch PowerTrench MOSFET | onsemi
The onsemi FDD8880 is a 30 V N-channel PowerTrench MOSFET rated for 58 A continuous drain current (at case temperature) with a maximum on-resistance of 9 mOhm, housed in a surface-mount TO-252AA (DPAK) package. It is currently in Last Shipments status, so new designs should plan for the alternatives listed on this page. A power MOSFET is a voltage-controlled semiconductor switch used to regulate or switch electrical power in circuits. Within the power-management hierarchy, discrete MOSFETs sit alongside integrated drivers and controllers, and the DPAK (TO-252AA) package family is one of the most widely used surface-mount power packages, providing a large exposed tab that solders directly to the PCB copper for heat spreading. The FDD8880 was specifically designed to improve the overall efficiency of DC/DC converters using synchronous or conventional switching PWM controllers. Its key differentiators are low gate charge, low rDS(on), and fast switching speed - three parameters that together minimize conduction and switching losses in high-frequency power conversion. Architecturally, the PowerTrench process uses a low charge, low resistance trench structure that reduces gate charge without sacrificing on-resistance. This makes the device well suited to high-frequency synchronous rectification, where total gate charge directly drives driver losses and switching speed affects transition losses. Typical applications include synchronous buck converters in point-of-load power supplies, DC/DC converter modules, and high-current load switches where a 30 V breakdown rating provides margin for 12 V rails and transient events. Design consideration: with 9 mOhm on-resistance, conduction losses at high current are significant (Estimated: I^2 x R gives ~0.34 W at 6.2 A, rising quadratically), so thermal design of the PCB copper area under the tab is critical. This page synthesizes distributor data, lifecycle status, drop-in alternatives, and practical design notes not consolidated in the manufacturer datasheet.
FDD8896 - 30V 94A N-Ch PowerTrench MOSFET | onsemi/Fairchild
The onsemi (Fairchild Semiconductor) FDD8896 is an N-Channel PowerTrench MOSFET rated 30 V drain-source voltage, 94 A continuous drain current at case temperature (17 A at ambient), 5.7 mOhm maximum on-resistance, and 80 W power dissipation at Tc, housed in a 3-pin TO-252 (DPAK) surface-mount package. A PowerTrench MOSFET is a trench-gate power transistor that belongs to the broader hierarchy of MOSFETs, discrete semiconductors, and power management components. Its vertical trench structure delivers very low on-resistance per unit die area and low gate charge, making it the workhorse switch element in modern power conversion stages where conduction losses and switching losses must both be minimized. Key features include the 5.7 mOhm rDS(ON) at 10 V gate drive, which minimizes I2R conduction loss; optimized low gate charge, which reduces driver loss and enables faster switching transitions; and the rugged TO-252 (DPAK) package that combines a small PCB footprint with the exposed drain tab for efficient heat spreading into the copper pour. Technically, the FDD8896 was designed specifically to improve the overall efficiency of DC/DC converters using either synchronous or conventional switching PWM controllers. In synchronous buck converters it is typically used as the low-side (sync) FET, where its low rDS(ON) dominates efficiency; it can also serve as the high-side switch in lower-duty-cycle rails. Typical applications include synchronous buck DC/DC converters for computer motherboards and point-of-load supplies, motor drive switching stages, and battery-powered systems requiring a low-loss 30 V-rated switch. Design consideration: at high current the DPAK relies on PCB copper for cooling; maximize drain-tab copper area and verify junction temperature with real thermal measurements. This page adds distributor sourcing data, pin-compatible alternatives, and practical design notes beyond what the manufacturer datasheet provides.
FDD8896-F085 - 30V 94A N-Channel PowerTrench MOSFET | onsemi
The onsemi FDD8896-F085 is a 30 V, 94 A N-Channel PowerTrench MOSFET optimized for high-efficiency DC/DC converters using synchronous or conventional switching PWM controllers. It is offered in a TO-252 (DPAK) surface-mount package with 5.7 mOhm maximum Rds(on) at Vgs = 10 V and a continuous drain current rating of 94 A at Tc = 25 C, plus 17 A at Ta = 25 C. The device is specifically engineered to deliver low gate charge and fast switching speed, reducing switching losses and improving overall converter efficiency. What is a PowerTrench MOSFET? A PowerTrench MOSFET is an N-channel power MOSFET built on a proprietary trench-gate process that creates a vertical channel under each cell, dramatically lowering on-state resistance per unit silicon area versus older planar DMOS structures. It belongs to the broader MOSFET hierarchy (MOSFET -> power MOSFET -> discrete semiconductor), and in modern SMPS topologies it acts as the synchronous-rectifier or main switch on the low-voltage side. The combination of low Rds(on), low Qg, and high current density makes it ideal for compact point-of-load and POL regulators. Key features of the FDD8896-F085 include 30 V Vdss, 5.7 mOhm Rds(on) at Vgs = 10 V, 94 A continuous drain current at 25 C case temperature, 80 W maximum power dissipation at Tc = 25 C, and an avalanche-rated body diode. The device is also characterized for low gate charge and fast switching, which enables high-frequency operation and reduced driver losses. It is qualified to AEC-Q101 for automotive reliability, and is available in a Halogen-free, lead-free DPAK surface-mount package. Typical applications include synchronous rectification in DC/DC converters, low-side switching in buck regulators, motor control and battery protection, hot-swap and OR-ing switches, and primary-side switching in isolated POL modules. The 30 V drain-source rating gives comfortable headroom for 12 V bus rails and 19 V adapter-fed systems, while the 5.7 mOhm on-resistance keeps conduction loss low at high currents. When designing with this part, calculate conduction loss as P = I_d^2 x Rds(on) and ensure that the resulting junction temperature stays below 150 C under worst-case ambient and cooling conditions. A small gate-drive resistor (typically 4.7 to 10 ohm) is recommended to control ringing and limit dV/dt-induced turn-on. For thermal reliability, mount the DPAK tab onto at least 1 sq inch of copper. This page synthesizes distributor pricing, AEC-Q101 automotive qualification details, drop-in TO-252 alternatives, and practical PCB-layout guidance that is not consolidated in the manufacturer datasheet alone. Engineers searching for a 30 V synchronous-rectifier MOSFET in DPAK will find the parametrics, cross-reference list, and SOA guidance needed for design-in and second-source decisions.
FDG6332C - 20V N&P-Channel PowerTrench MOSFET | onsemi SC-88
The onsemi FDG6332C is a dual N- and P-channel MOSFET array in a 6-pin SC-88 (SC-70-6) surface-mount package, built on onsemi's advanced PowerTrench process to minimize on-state resistance while preserving fast switching performance. The N-channel device is rated 20 V VDS with 700 mA continuous drain current, and the P-channel device shares the same 20 V rating with 600 mA continuous drain current. Total package power dissipation is rated 300 mW with junction-to-ambient thermal resistance of 415 °C/W on a JEDEC still-air PCB, meaning the array must be evaluated against PCB copper area for thermal derating. A MOSFET array is an integrated semiconductor device that places two or more discrete MOSFETs in a single chip-scale package, allowing complementary switching (high-side plus low-side, or N+P fetches in a half-bridge) without the board area of two separate SOT-23 or SOT-363 parts. MOSFET arrays occupy a place in the hierarchy: power MOSFET, power semiconductor, discrete semiconductor, and ultimately integrated circuit packaging. They are commonly used in load switching, level shifting, and DC-DC converter synchronous stages where board real estate is at a premium. Key differentiating features of the FDG6332C include its monolithic dual-channel topology, ultra-small SC-88 outline (approximately 2.0 × 2.1 mm), 20 V VDS rating suitable for 5 V and 12 V buses, low RDS(on) for both polarities via PowerTrench cell design, and a logic-level gate threshold compatible with 1.8 V and 3.3 V microcontrollers. The complementary N+P channel arrangement allows a single part to perform synchronous-rectifier, inverter, or H-bridge functions in miniature footprints. Architecturally, the FDG6332C uses a trench-gate structure that maximizes channel density per unit silicon area, reducing both on-resistance and gate charge. The N-channel and P-channel dies are independently bonded out to separate source pins, eliminating the need to parallel discrete parts and reducing parasitic source inductance that would otherwise degrade switching edge rates. Typical applications include portable and battery-powered load switching (USB VBUS switches, lithium-ion protection circuits, OLED display drivers), low-voltage DC-DC synchronous buck converters in consumer and IoT devices, signal-level shifters between MCUs and higher-voltage loads, and small motor or relay drivers in white goods and personal electronics. When designing with the FDG6332C, pay attention to gate-drive headroom and to PCB thermal copper area: 415 °C/W RθJA means continuous 300 mW is only attainable with substantial copper pours or with pulsed operation where average power remains low. Verify that the chosen gate drive can fully enhance both channels at the intended VGS. This page synthesizes distributor pricing, package-matched equivalents, thermal estimates, and design notes that supplement the manufacturer datasheet.
FDG6332C-F085 - 20V N&P Chan MOSFET Array | onsemi | SC-70-6
The onsemi FDG6332C-F085 is a 20V N-channel and P-channel complementary PowerTrench MOSFET array rated at 700 mA (N-FET) and 600 mA (P-FET) continuous drain current, housed in a 6-pin SC-88/SC-70-6 (SOT-363) surface-mount package. The dual-FET die integrates one N-channel and one P-channel MOSFET in a tiny footprint optimized for portable load-switching and small-signal power management. A PowerTrench MOSFET is a small-signal MOSFET fabricated with a trench-gate process that increases cell density and reduces on-state resistance (RDS(on)) per unit silicon area. In a complementary N+P pair such as the FDG6332C-F085, designers use the N-channel device for high-side or low-side switching of positive rails and the P-channel device for high-side reverse-polarity or load-disconnect switching of the same rail - functions that together cover virtually every discrete switching need in a portable battery-powered system. MOSFET arrays are classified under small-signal discrets, a sub-family of discrete semiconductors that also includes single MOSFETs, IGBTs, and protection devices. Key features of the FDG6332C-F085 include a 20V VDS rating that comfortably covers 1-cell Li-ion (4.2V max), 3.3V and 5V rails, and 12V bus transients; low RDS(on) values typical for the PowerTrench family at VGS = 4.5V and 2.5V; fast switching speeds thanks to low gate charge; and a 300 mW power dissipation rating in the SC-70-6 package. The -F085 suffix denotes the automotive AEC-Q100 qualified grade, screened for higher reliability than the standard commercial FDG6332C. Internally, both FETs share a common drain-substrate layout that allows the package to fit two independent devices in a 2.0 x 1.25 mm body. The P-channel transistor typically has higher RDS(on) than the N-channel at the same VGS - this asymmetry is normal and is one of the reasons complementary pairs are co-designed. Designers selecting this part should bias the gates with logic-level (1.8V/2.5V/3.3V) drive signals rather than higher voltages to stay within the VGS(max) envelope and to minimize conduction losses. Typical applications include portable/battery-powered load switching, USB power switching, Li-ion charger reverse-polarity protection, signal gating, motor-driver direction control, and small-signal DC-DC converters. The AEC-Q100 qualification also makes the -F085 grade suitable for automotive body-electronics modules, infotainment peripherals, and other in-cabin circuits that demand automotive-grade reliability. When designing with this array, keep gate-drive traces short to limit ringing, and place gate-source pull-down resistors (typically 100 kohm to 1 Mohm) on both FETs to ensure a known off-state when the controller is in reset. The SC-70-6 footprint requires careful paste-stencil aperture design to avoid solder bridging on the closely spaced leads - a 4-mil stencil with aperture reduction on inner pads is a common best practice. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the onsemi datasheet alone, giving you the parametric data needed to choose the FDG6332C-F085 for portable, automotive, or industrial switching tasks.
FDMC510P - 20V P-Channel PowerTrench MOSFET | onsemi
The onsemi FDMC510P is a P-Channel PowerTrench MOSFET rated at -20 V VDS and -18 A continuous drain current (ID), with a maximum on-resistance of 8.0 mΩ at VGS = -10 V, housed in an 8-MLP (3.3 x 3.3 mm) Power33 surface-mount package. Designed using onsemi's advanced POWERTRENCH process, the FDMC510P is optimized for low rDS(on), fast switching, and ruggedness in space-constrained designs. The device is rated for 2.3 W power dissipation at TA = 25 °C and 41 W at TC = 25 °C, making it suitable for both PCB-area-limited and thermally-poured layouts. A P-Channel MOSFET (PMOS) is a type of field-effect transistor where the channel is formed by p-type semiconductor material and conducts current when a negative gate-source voltage (VGS) is applied. In the power management taxonomy, PMOS belongs to MOSFET -> discrete semiconductor -> power switch. P-Channel devices are commonly used as high-side switches because their source connects to the load supply, enabling simple gate-drive to ground via a low-voltage control signal. This architecture eliminates the bootstrap circuitry often required by N-Channel high-side switches, simplifying designs in battery and load-management applications. Key features of the FDMC510P include 8.0 mΩ typical rDS(on) at -10 V VGS, low gate charge for fast switching, integrated ESD protection, and a logic-level-friendly gate threshold that is compatible with 1.8 V to 5 V GPIO drive. The MLP-8 (3.3 x 3.3) Power33 package offers an exposed pad that significantly reduces thermal resistance (RθJA), enabling the 41 W TC rating while occupying only 10.89 mm² of board area. Compared to older DPAK or SO-8 footprints, the FDMC510P delivers a smaller, thinner profile suitable for portable and space-constrained electronics. Technically, the FDMC510P uses a trench-gate structure that increases cell density and reduces on-resistance per unit area. The P-Channel polarity simplifies high-side switching in battery-powered systems because the source sits at the battery voltage and the load connects to ground via the drain, allowing the gate to be driven by a low-voltage logic signal referenced to ground. This eliminates the charge pump or bootstrap needed for N-Channel high-side switches, saving board space and reducing quiescent current. Typical applications include battery protection circuits, load switches in portable devices, power-rail OR-ing, USB power switching, and DC-DC converters. The -20 V rating provides sufficient headroom for 12 V systems while maintaining low conduction loss at 5 V and below. When designing with the FDMC510P, ensure the gate-source voltage never exceeds the ±20 V absolute maximum and that the exposed pad receives a continuous copper pour to achieve the rated thermal performance. For high-frequency switching, a small gate-source resistor (10-100 Ω) helps dampen parasitic ringing without significantly slowing turn-on. This page synthesizes distributor pricing, verified drop-in alternatives, and practical PCB thermal guidance not aggregated on a single manufacturer page, giving engineers a faster sourcing and design decision.
