DMT10H015LCG-7 - 100V N-Channel MOSFET, 34A, V-DFN3333-8 | Diodes Inc
The Diodes Incorporated DMT10H015LCG-7 is a 100V N-Channel Enhancement Mode MOSFET housed in a compact V-DFN3333-8 (3.3mm x 3.3mm) surface-mount package, designed to minimize on-state resistance while maintaining superior switching performance. The device is rated for 9.4A continuous drain current at ambient (Ta) and 34A at case temperature (Tc), with a maximum power dissipation of 1W (Ta) per the manufacturer datasheet. An N-Channel Enhancement Mode MOSFET (often abbreviated N-FET or NMOS) is a voltage-controlled switching transistor that conducts current between drain and source when a positive gate-to-source voltage exceeding the threshold is applied. Within the discrete components taxonomy, MOSFETs are a sub-category of transistors (MOS transistor -> transistor -> discrete semiconductor -> electronic component). N-Channel enhancement-mode parts are the dominant polarity in modern switching converters because they offer roughly 2-3x lower RDS(ON) per unit silicon area than equivalent P-Channel devices, which directly improves efficiency and thermal performance. Key features of the DMT10H015LCG-7 include an industry-standard 100V drain-to-source breakdown voltage (BVDSS) covering the 61V-100V MOSFET class, low on-state resistance for reduced conduction losses, fast switching characteristics suitable for high-frequency DC-DC converters, and a thermally enhanced DFN package with an exposed die-attach pad that lowers junction-to-ambient thermal resistance. The 3.3mm x 3.3mm outline with a central thermal pad enables high current handling in space-constrained PCB layouts. Technically, the device uses Diodes Incorporated's latest-generation trench MOSFET process to balance low RDS(ON) with low gate charge (Qg). This combination matters in switching applications because total switching loss scales with Qg x Vdrive x Fsw; a low Qg keeps the gate-drive burden on the controller manageable and allows higher switching frequencies without excessive driver losses. The V-DFN3333-8 footprint is JEDEC-compatible with standard DFN3333 land patterns used across the industry. Typical applications include notebook battery power management (load switch, battery protection, OVP/OCP disconnect), synchronous rectification in isolated and non-isolated DC-DC converters, hot-swap circuits on 48V telecom rails, motor drive H-bridges for low-voltage brushless DC fans and small pumps, and high-side load switching in industrial 24V systems. The 100V rating provides ample derating margin on 24V industrial and 48V telecom buses. When designing with this MOSFET, ensure the gate-drive voltage meets the Vgs(th) and plateau requirements of the controller; insufficient gate drive dramatically increases RDS(ON) and conduction loss. Place the gate-driver loop area and the power loop (input cap -> high-side FET -> low-side FET -> GND) as small as possible to minimize parasitic inductance that causes voltage overshoot and switching losses. This page synthesizes distributor pricing (as of 2026-10-05), drop-in alternatives from the manufacturer portfolio, and practical design notes that go beyond the bare spec table found in the manufacturer datasheet.

When designing with this module, verify the exact package outline, terminal arrangement, and gate resistor recommendations from the manufacturer datasheet before committing to a PCB or busbar layout, as Danfoss module mechanical variants differ across the DP-series family. Thermal interface material selection and heatsink flatness directly affect junction temperature margins. This page synthesizes distributor availability data, datasheet references, and sourcing guidance for the DP15H1200TO101982 that is not consolidated on the manufacturer's site, helping engineers evaluate drop-in feasibility and procurement options in one place.
DRDNB21D-7 - Dual Relay Driver Array, 100mA, SOT-363 | Diodes Inc
The Diodes Incorporated DRDNB21D-7 is a complex array for dual relay driver applications, integrating two pre-biased NPN transistors and two switching diodes in a single SOT-363 (SC-88, 6-TSSOP) surface-mount package. According to the Diodes Incorporated datasheet, the device is rated for 100 mA output current per channel in a 1:1 bipolar power switch/driver topology, with a peak output capability suitable for inductive relay and solenoid loads. What is a relay driver array? A relay driver array is an integrated multi-component module that consolidates the discrete transistors, base resistors, and free-wheeling diodes typically required to drive electromechanical relays or similar inductive loads. By packaging these elements together, the array reduces PCB footprint, simplifies BOM, and improves reliability by eliminating wiring errors between discrete components. The DRDNB21D sits at the top of the discrete semiconductor hierarchy: relay driver array -> power switch/driver -> PMIC -> semiconductor device. Key features include epitaxial planar die construction, integrated pre-biased transistor configuration that eliminates external base resistors, and built-in switching diodes that protect against back-EMF from inductive loads. The compact SOT-363 package measures only 2.0 mm × 1.25 mm × 0.95 mm, enabling high-density PCB layouts. Surface-mount termination supports tape-and-reel packaging for automated assembly processes, and the device is RoHS compliant. The DRDNB21D-7 functions as a 1:1 low-side power switch with bipolar transistor technology. The integrated architecture allows each channel to sink up to 100 mA continuously, with internal base biasing networks sized to interface directly with logic-level microcontroller GPIO pins (typically 3.3 V or 5 V). The switching diodes are oriented to clamp inductive kickback when the relay coil is de-energized, protecting the driver transistors from reverse-voltage transients. Typical applications include automotive relay modules, industrial control boards driving small signal relays or solenoids, HVAC control circuits, and home appliance switching subsystems. The device is also commonly used in telecom line cards and security system relay drivers where a compact, integrated solution reduces board area and assembly cost. When designing with the DRDNB21D-7, ensure that the relay coil current does not exceed 100 mA per channel and that PCB traces to the relay can handle the peak inrush current. The integrated diodes eliminate the need for external flyback protection, but thermal management of the SOT-363 package becomes critical at high duty cycles above 50%.

DRTR5V0U2SR-7 - 2-Channel 5V TVS Array | Diodes Incorporated
The Diodes Incorporated DRTR5V0U2SR-7 is a two-channel, low-capacitance transient-voltage-suppressor diode array designed for electrostatic-discharge protection on sensitive data lines. The device is specified for a 5.5 V unidirectional clamp condition, 5 A peak pulse current, 400 mW power rating, and 1.0 pF capacitance in a four-pin SOT-143 surface-mount package. Its low capacitance makes it suitable for high-speed communication interfaces where added signal capacitance must remain limited. A TVS diode array is a discrete protection component that diverts transient voltage away from a protected circuit while presenting a high-impedance path during normal operation. The DRTR5V0U2SR-7 belongs to the broader ESD-protection and circuit-protection hierarchy, alongside surge suppressors, clamping diodes, and interface-protection devices. Two protected channels in one compact package simplify board layout compared with separate single-line protection devices, provided that the channel assignments and footprint are checked against the selected interface. The verified distributor descriptions identify this part as a two-channel low-capacitance TVS array with 1.0 pF capacitance, 5 A peak pulse current, and 400 mW power. The manufacturer datasheet search result lists high-speed applications including USB 2.0, IEEE 1394, Serial ATA, DVI, HDMI, and PCI. The exact clamping voltage, leakage current, working voltage, response time, and detailed pin mapping are not present in the supplied source snippets and therefore are not inferred here. The SOT-143 package is intended for compact PCB placement and surface-mount assembly. Because a protection device is normally placed close to the connector or protected interface, trace length and return-path continuity are important. The PCB land pattern should follow the manufacturer footprint, and the protection device should not be placed where long unprotected traces can carry an ESD transient back toward the protected circuitry. Validate the final design against the applicable interface standard and the device’s complete electrical ratings. Typical uses include USB, high-speed serial links, Ethernet-PHY protection, HDMI, PCI, DVI, and other exposed connector lines. For those applications, the 1.0 pF figure is the principal verified low-capacitance feature, while the 5 A and 400 mW figures describe the supplied transient and power ratings. Do not use those figures as a substitute for the complete datasheet rating table when sizing surge exposure or selecting a replacement. This page consolidates the verified distributor information, official manufacturer link, datasheet link, packaging data, and application guidance. It also separates confirmed values from unavailable electrical details so engineers can make an informed sourcing and design decision without relying on unverified specifications.
DUP2105SOQ - 24V Dual CAN/LIN Bus TVS Protector | Diodes
The Diodes Incorporated DUP2105SOQ is a dual-line CAN bus protector TVS diode array rated for a 24V reverse standoff voltage, 44V clamping voltage, and 8A peak pulse current (Ipp), housed in a 3-pin SOT-23 surface-mount package. This Automotive AEC-Q101 qualified device provides bi-directional ESD and transient protection for two bus lines in a single footprint. A TVS (Transient Voltage Suppressor) diode is a clamping device in the broader family of circuit protection components - alongside surge protectors, varistors, and ESD suppressors - that diverts harmful transient energy away from sensitive ICs. Bus protector arrays like the DUP2105SOQ are specialized TVS devices optimized for differential communication lines such as CAN (Controller Area Network) and LIN (Local Interconnect Network), where two lines must be clamped symmetrically to ground without distorting bus signaling. Key features include a 24V working standoff voltage that accommodates automotive 12V and 24V bus rails with margin, an 8A Ipp surge rating per the 8/20us pulse standard, and low clamping voltage of 44V that keeps downstream CAN/LIN transceiver pins within their absolute maximum ratings. The device meets stringent automotive ESD requirements, protecting against ESD, EMI, and other harmful transient voltage events specified in automotive OEM specifications. Architecturally, the DUP2105SOQ integrates two bi-directional TVS elements sharing a common structure in one low-capacitance die arrangement, minimizing parasitic contribution to the bus while providing symmetric clamping. Its small SOT-23 footprint lets it be placed directly at the transceiver-side connector, the position where protection is most effective because transient energy is diverted before it propagates along PCB traces. Typical applications include CAN bus protection in body control modules, LIN transceiver protection in door modules and seat controllers, gateway modules, automotive sensor interfaces, and industrial CAN networks exposed to harsh transients. The new-generation TVS design is explicitly targeted at automotive LIN and CAN transceiver protection per the manufacturer datasheet. When designing with this device, place it as close as possible to the CAN/LIN connector or transceiver pins, and keep the ground return path short and low-inductance; the protection quality depends heavily on layout, not just the diode ratings. Verify the clamping voltage at your expected surge current leaves margin under the transceiver absolute maximum.

E(T - Component Reference | Datasheet Search Resource
The MPN string "E(T" is not a complete, validated electronic component part number; it appears in retrieved web data only as a fragment of suffix-flagged bipolar transistor parts (for example Unisonic Technologies 2SD882-E-T, S8050L-E-T, HE8050-E-T, 2SB772-E-T) and does not map to a unique catalog device on its own. Per data-authenticity rules this page records E(T as a non-resolvable token rather than guessing a specific manufacturer, package, voltage, or current rating. A suffix-flagged bipolar junction transistor (BJT) is a discrete semiconductor in which the die is identified by an alphanumeric manufacturer suffix such as "-T" or "-E-T" that typically denotes tape-and-reel packaging, lead-free finish, and/or an engineering sample. Within the BJT taxonomy, these parts are NPN or PNP silicon transistors used for small-signal amplification and low-power switching, which sit below regulators and gate drivers in the discrete-semiconductor -> transistor -> BJT hypernymy chain. The "-E-T" suffix convention in the verified Unisonic Technologies dataset collocates with low-VCEO NPN small-signal transistors (e.g., S8050L-E-T, HE8050-E-T), suggesting tooling tape-and-reel, lead-free (Pb-free) finish, and a 92-style TO-92-like through-hole package. Engineers commonly use the full MPN plus suffix when sourcing, because bare stems like "E(T" cannot reliably disambiguate the underlying die. Typical end-equipment applications for the underlying -E-T suffixed BJTs include small-signal amplification stages in audio pre-amplifiers, low-side switching in relay and solenoid driver circuits, level-shifting interfaces between logic-level microcontrollers and higher-current loads, and general-purpose linear regulators or sensor signal conditioning. When evaluating a quoted "E(T" string, request the full MPN plus suffix from your vendor, then cross-check the resulting datasheet against parameters such as VCEO, IC continuous, hFE, and package outline before placing the part on a BOM. If a quoted string omits the prefix, the buyer is exposed to mis-shipping risk. This page combines partial-token web data, validated Unisonic suffix conventions, and a list of recommended full-MPN drop-in candidates so engineers can resolve ambiguous "E(T" quotations into a buyable, traceable part number.
EMB10T2R - Dual PNP Digital Transistor 50V 100mA EMT6 | ROHM
The Rohm Semiconductor EMB10T2R is a dual PNP pre-biased bipolar transistor array housed in a compact EMT6 (SOT-563 equivalent) surface-mount package. Each channel integrates a PNP bipolar junction transistor with built-in bias resistors, forming a complete digital transistor in a single chip that requires only one external resistor (the base series resistor R_B) for switching operation. A digital transistor (also called a bias-resistor-built-in transistor, or BRT) is a discrete BJT with one or two monolithic resistors integrated on the same die, replacing the discrete base-resistor network that designers would otherwise place around a standard transistor. It belongs to the hierarchy: digital transistor -> pre-biased BJT array -> bipolar transistor array -> discrete semiconductor. The integration of bias resistors eliminates roughly three external components per channel and removes the need for precise resistor matching, which simplifies PCB layout, shrinks BOM count, and improves switching consistency in high-volume manufacturing. Key features include a collector-emitter voltage rating of 50V, continuous collector current of 100mA per channel, transition frequency of 250 MHz, and total device power dissipation of 150 mW. The package is a 6-lead EMT6 measuring approximately 1.6 mm x 1.6 mm, making it among the smallest dual-transistor products on the market. The integrated bias resistors are 10 kohm typical, and the design supports direct drive from MCU GPIO pins or logic-level signals without external biasing components. The architecture uses a PNP silicon epitaxial planar die with polysilicon bias resistors, providing tight R1/R2 tolerance and good thermal matching between the two channels. The symmetrical dual-channel layout simplifies PCB routing for complementary switching or differential amplifier front-ends. Typical applications include interface circuits, level shifters, signal buffering, LED driver for museum display panels, and pre-amplifier differential amplification in portable devices. It is also used as a high-frequency oscillator building block and gate driver for low-power MOSFETs in industrial control modules. When designing with this device, note that Rohm has designated the EMB10 as Not Recommended for New Designs. For new designs, evaluate the UMB10N (industry equivalent) or IMB10A (industry equivalent) families. The dual-channel matching makes it well-suited for differential pairs where channel-to-channel gain and Vbe tracking matter.

EPC2034C - 200V, 48A eGaN FET | EPC | Surface Mount Die
The Efficient Power Conversion EPC2034C is a 200 V, 48 A enhancement-mode Gallium Nitride (eGaN) power transistor supplied as a passivated die with surface-mount terminals, exhibiting 8 mOhm typical RDS(on). The part is rated for 213 A pulsed drain current per the EPC product page, with a 200 V drain-source breakdown and a small die footprint optimized for high-frequency switching converters where silicon MOSFETs reach their practical limit. An eGaN FET (enhancement-mode Gallium-Nitride-on-Silicon FET) is a wide-bandgap power transistor that replaces silicon MOSFETs and IGBTs in high-frequency, high-efficiency power conversion. GaN's higher electron mobility and lower gate/output charge translate into lower switching losses, smaller magnetics, and higher power density. Within the EPC product hierarchy, eGaN FETs sit alongside gate drivers and integrated half-bridges as the discrete switching element for DC-DC, AC-DC, and wireless-power topologies. Key specifications of the EPC2034C include 8 mOhm RDS(on) at the recommended gate drive, 200 V VDS rating, 48 A continuous drain current at Ta (per DigiKey listing), and gate charge characteristics that support multi-MHz switching. The die form factor eliminates the parasitic inductance and thermal resistance of a discrete package, allowing tighter loop layouts and lower junction-to-case thermal impedance. The architecture uses EPC's GaN-on-silicon process with a lateral structure that gives exceptionally low QGD/QGS ratios and near-zero reverse-recovery charge. Compared with a similarly-rated 200 V silicon MOSFET, the EPC2034C typically cuts switching loss by an order of magnitude in hard-switched topologies and enables topologies that are impractical in silicon, such as hard-switched 48 V point-of-load converters operating above 1 MHz. Typical applications include 48 V point-of-load converters for datacom/telecom, synchronous rectification in high-density DC-DC bricks, Class-D audio amplifiers, RF envelope tracking, and wireless-power transmit stages. The 200 V rating also suits LED laser driving and small motor drive stages where dead-time losses dominate. When designing with the EPC2034C, keep gate-drive loops minimal (the part's low internal inductance makes external layout critical), use a 5 V gate drive with a recommended negative turn-off option, and account for the surface-mount die handling requirements during PCB assembly. EPC evaluation kits provide reference layouts and recommended gate drivers. This page consolidates distributor pricing, parametric drop-in candidates, and practical PCB-layout notes that are not collected in the manufacturer datasheet alone.
EPC2045 - 100V, 7mΩ, 16A GaN FET | EPC | eGaN Power Transistor
The Efficient Power Conversion EPC2045 is a 100V enhancement-mode Gallium Nitride (eGaN) power transistor delivering 16A continuous drain current with an ultra-low 7 mΩ on-resistance, housed in a passivated die/wafer-level surface-mount package. It features a pulsed drain current rating of 130A, making it well suited for high-frequency, high-current pulsed-power circuits. According to the EPC2045 datasheet from Efficient Power Conversion, the device is RoHS 6/6 compliant and halogen-free, targeting applications that demand higher efficiency and power density than silicon MOSFETs. What is a GaN FET (Gallium Nitride Field-Effect Transistor)? A GaN FET is a wide-bandgap semiconductor power switch that offers lower switching losses, higher switching frequency capability, and lower on-resistance per area compared to traditional silicon MOSFETs. The EPC2045 belongs to EPC's eGaN FET family, which is the enhancement-mode GaN-on-Silicon technology that replaces silicon MOSFETs in point-of-load converters, LiDAR pulsers, and high-frequency DC-DC converters. Within the broader taxonomy, GaN FETs are a subclass of discrete power transistors -> discrete semiconductors -> semiconductors. Key features of the EPC2045 include 100V drain-source voltage rating, 7 mΩ typical RDS(on), 16A continuous drain current, 130A pulsed drain current, and exceptionally low gate charge (Qg) and reverse-recovery charge (Qrr) compared to silicon superjunction MOSFETs. The lack of a body diode reverse-recovery charge eliminates dead-time losses in hard-switched half-bridges, enabling higher frequency operation. The wafer-level chip-scale package (WLCSP / bare-die) minimizes parasitic inductance and allows direct attachment to the PCB. Typical applications for the EPC2045 include Open Rack Server Architectures (V1, V2, V3), LiDAR/Pulsed Power applications, USB-C Power Delivery cables and connectors, isolated power supplies (telecom bricks), and point-of-load converters. The combination of low RDS(on), high pulsed current, and very fast switching speeds makes it a strong replacement for 100V silicon MOSFETs in compact high-frequency designs where the silicon FET's Qrr dominates switching losses. When designing with the EPC2045, drive the gate with a GaN-optimized gate driver that provides 5V VGS and clean miller clamping to avoid false turn-on. Place bypass capacitors as close as possible to the source-sense pads to minimize high-frequency ringing in the 100+ MHz range.
ES1D - 1A 200V Ultra-Fast Recovery Rectifier SMA | onsemi
The onsemi ES1D is a 1 A ultra-fast recovery rectifier diode rated at 200 V reverse voltage, packaged in a surface-mount DO-214AC (SMA) outline. It is designed for high-efficiency rectification in switch-mode power supplies, freewheeling paths, and DC-DC converter secondary stages where conventional 50 Hz rectifiers would be too slow. Per the onsemi datasheet, the ES1D delivers reverse recovery time (trr) on the order of tens of nanoseconds, dramatically reducing switching loss compared with standard recovery rectifiers. An ultra-fast recovery rectifier is a discrete semiconductor that conducts current in one direction and switches from the conducting to the blocking state in a very short interval, typically under 50 ns. The hyperfast/ultrafast family sits between standard recovery rectifiers (trr in the microsecond range) and Schottky diodes, combining acceptable forward voltage with the high reverse voltage that Schottky parts cannot reach. In the broader taxonomy: rectifier diode -> discrete semiconductor -> power diode -> semiconductor device. ES1-series parts are surface-mount equivalents to legacy axial-lead 1N493x devices. The key features of the ES1D include a 200 V maximum repetitive peak reverse voltage (VRRM), a 1.0 A average rectified forward current at TL = 75 C, a low-profile SMA package suitable for automated pick-and-place, a built-in strain-relief construction, and a glass-passivated junction for long-term reliability. The maximum forward surge current is typically rated at 25-30 A for an 8.3 ms half-sine pulse. The ES1D uses a glass-passivated silicon die with a single P-N junction, optimizing carrier lifetime to achieve fast switching without sacrificing surge capability. Its junction-to-ambient thermal resistance in the SMA footprint (with standard 2 oz copper pad) is roughly 75-85 C/W, so a continuous 1 A load at 150 C junction limit implies a mounting-free operating window; designers should verify copper area for high-duty applications. Typical applications include switch-mode power supply secondary rectifiers, freewheeling diodes across inductive loads, polarity-protection circuits, and high-frequency DC-DC converter outputs. Its ultra-fast recovery also makes it suitable for the output stage of small flyback or forward converters operating at 50-200 kHz. When designing with the ES1D, observe that the 1 A average current rating assumes the lead temperature is held at 75 C or below; on a small SMD footprint the part may derate well before 1 A. For continuous high-current service consider larger SMA-equivalent packages such as SMB (DO-214AA) or SMC (DO-214AB). This page synthesizes verified distributor listings, parametric cross-reference data, and practical SMA-layout design guidance not collected in a single manufacturer datasheet, supporting engineering decisions for sourcing, second-source qualification, and PCB layout.
ES1D-13-F - 200V 1A Super-Fast Rectifier Diode | Diodes Inc
The Diodes Incorporated ES1D-13-F is a surface-mount super-fast recovery rectifier diode rated at 200V reverse voltage and 1A average forward current, housed in a 2-pin SMA (DO-214AC) package. It features a low forward voltage drop of 0.92V typical at 1A and an ultra-fast reverse recovery time of 25ns, enabling high-efficiency rectification in switched-mode power supplies. A rectifier diode is a semiconductor device that allows current to flow in only one direction, converting alternating current (AC) to direct current (DC). Super-fast recovery rectifiers are a specialized subset optimized for high-frequency switching applications where standard rectifier diodes would suffer excessive switching losses. The ES1D sits within the discrete semiconductor > diodes > rectifier > super-fast recovery hierarchy, bridging power management ICs and passives in modern switch-mode designs. Key specifications include a peak repetitive reverse voltage (VRRM) of 200V, average rectified forward current (IF(AV)) of 1.0A, forward voltage (VFM) of 0.92V at 1A and 0.90V at 0.6A, peak reverse current of 5.0µA at 25°C (200µA at 125°C), and total capacitance that supports high-frequency operation. The molded plastic case with solderable matte tin-plated copper lead-frame terminals conforms to MIL-STD-202 mechanical and solderability standards. The SMA footprint is the industry-standard surface-mount rectifier outline, enabling direct drop-in substitution on most PCB land patterns. The ES1D-13-F leverages a glass-passivated die with a low-leakage, high-speed junction, providing 25ns reverse recovery and excellent thermal stability across the -55°C to +150°C operating junction range. With a thermal resistance of approximately 25°C/W on a standard JEDEC test board, the device sustains full 1A operation in moderate ambient conditions without external heatsinking. Typical applications include secondary rectification in AC-DC adapters, freewheeling diodes across switching converters, snubber and clamp circuits, polarity protection in DC distribution, and high-frequency rectification in telecom and industrial SMPS designs. The 25ns recovery time is particularly advantageous at 100kHz+ switching frequencies where slower diodes would dissipate substantial switching power. When designing with the ES1D-13-F, ensure the PCB land pattern conforms to the JEDEC DO-214AC (SMA) footprint and respect the 200V reverse-voltage derating guidelines for reliable operation. For continuous 1A loads, verify junction temperature stays below 150°C by calculating power dissipation (IF × VFM) against the system thermal resistance budget.

ESD1LIN24DYFRQ1 - 24V LIN ESD Protection TVS | TI | Q1
The Texas Instruments ESD1LIN24DYFRQ1 is an automotive-grade, single-channel bidirectional ESD protection diode (TVS) rated at ±24 V working voltage with ±30-kV contact and ±30-kV airgap IEC 61000-4-2 ESD robustness, housed in a 2-pin SOD-323 surface-mount package. An ESD protection diode, also called a TVS (transient voltage suppressor) diode or ESD suppressor, is a two-terminal semiconductor device that clamps fast overvoltage transients before they reach sensitive circuitry. Within the power/signal-protection hierarchy, it sits below surge arresters and above simple RC filters, forming the first line of defense in automotive power management and in-vehicle networking interfaces such as LIN (Local Interconnect Network) bus nodes. Key features of the ESD1LIN24DYFRQ1 include very low junction capacitance of approximately 2.3 pF to 3 pF, which preserves signal integrity on LIN bus lines up to 19.2 kbps and beyond; a 37 V typical clamping voltage with 4.3 A (8/20 us) Ipp surge capability; and low dynamic resistance, which keeps the clamped voltage low during high-current ESD strikes. The -Q1 suffix confirms AEC-Q100 automotive qualification and support for -40C to +150C operation, well beyond most industrial-grade suppressors. Architecturally, the device is a bidirectional avalanche-type clamp: no polarity orientation is required on the asymmetric line, simplifying assembly. Its low dynamic resistance means the rail voltage rises only minimally as ESD current increases, protecting downstream LIN transceivers and MCU IO pins. TI also offers the related ESD751-Q1 and ESD761-Q1 in leaded packages for easy through-routing on the protected line. Typical applications include LIN bus ESD protection in body-control modules, door modules, seat controllers, and wiper/lighting nodes; 12 V and 24 V automotive rail protection; and industrial 24 V sensor lines exposed to field wiring transients. Design consideration: place the diode within a few millimeters of the connector, with a short, direct ground return path, since series inductance in the trace degrades clamping effectiveness during nanosecond-scale ESD events. This page adds value beyond the manufacturer datasheet by synthesizing distributor pricing, drop-in family alternatives, comparison tables, and practical layout guidance for LIN ESD protection design.
ESD1P0RFS - 1 pF 2-Channel RF ESD Diode | Infineon
Infineon ESD1P0RFS is a 2-channel RF ESD protection diode with 1 pF typical capacitance and 6 gull-wing terminals in a surface-mount package. It is intended to protect RF antenna and interface lines, ultra-high-speed data lines, and other low-capacitance signal paths. According to the verified manufacturer documentation, the device provides ±20 kV contact ESD protection, 10 A surge compliance, and protection referenced to IEC61000-4-2, IEC61000-4-4, and IEC61000-4-5. What is an RF ESD protection diode? It is a transient-voltage-suppressor diode designed to divert electrostatic discharge energy away from a sensitive circuit while introducing very little capacitance into the protected signal. ESD1P0RFS is a low-capacitance, multi-line protection device, placing it in the interface-protection hierarchy between passive circuit protection and the protected RF or high-speed interface. The principal feature is the 1 pF typical capacitance, which helps preserve signal integrity on RF and high-speed lines. The verified data identifies four RF ESD protection diodes in the six-terminal device and describes use for one protected signal line in an anti-parallel configuration. The application example also notes that a protected line may carry superimposed DC voltage up to ±2 × VF, where VF is the diode forward voltage. Technically, the device combines low capacitance with high transient-energy handling. Its 2-channel arrangement allows two signal conductors or related interface lines to be protected in a compact footprint. The 70 V rating reported for the related distributor listing describes the device category and ordering context, while the verified series document supplies the application example and protection references. Typical uses include RF antenna inputs, GPS, HDMI, Ethernet interfaces, communications equipment, and ultra-high-speed data-line protection. In these systems, capacitance affects edge bandwidth, insertion loss, and signal integrity; a 1 pF device is selected when the interface must remain responsive while exposed to ESD events. PCB placement is important. Place the protection device close to the connector or board entry, connect the protected line through the device as shown in the manufacturer application example, and keep high-current surge paths away from sensitive logic. Verify the complete interface against the applicable system ESD, EFT, and surge requirements rather than relying only on the device rating. This page consolidates the verified Infineon series documentation, distributor information, technical parameters, protection standards, and design considerations for faster component selection and PCB implementation.
ESD1P0RFS-E6327 - 2-Channel 70V 10A TVS Array | Infineon
Infineon ESD1P0RFS-E6327 is a two-channel transient-voltage-suppressor diode array designed for RF and high-speed signal-line protection. Its verified headline ratings are 70 V reverse standoff voltage, 10 A surge current, 1 pF typical capacitance, and ±20 kV contact ESD protection. The device is supplied in a surface-mount SOT-363 package, also identified in the supplied data as 6-TSSOP/SC-88. A TVS diode array is a semiconductor protection component connected to sensitive signal lines. During an electrostatic discharge or transient event, the array diverts surge energy away from the protected circuit and clamps the signal voltage to a safer level. ESD1P0RFS belongs to the discrete-semiconductor protection hierarchy: TVS diode array, surge suppressor, ESD protection device, and discrete semiconductor. The principal feature of ESD1P0RFS-E6327 is its low typical capacitance of 1 pF. Low capacitance helps preserve high-frequency signal behavior while still providing transient protection. Infineon’s application material identifies ESD1P0RFS as a low-capacitance anti-parallel configuration for one protected signal line with superimposed DC voltage, making it relevant to RF antennas, communications interfaces, and ultra-high-speed data lines. The verified search results also identify applications including GPS, HDMI, and Ethernet. The array provides two-channel protection in a compact surface-mount package. Its verified protection claims include ±20 kV contact ESD and 10 A surge compliance, while the supplied comparison data lists IEC61000-4-2, IEC61000-4-4, and IEC61000-4-5 test categories. The 70 V standoff rating should not be interpreted as a general-purpose mains surge suppressor; engineers must verify that the protected signal, working voltage, and transient waveform remain within the device’s specified limits. Typical RF placement is close to the connector or exposed interface, with the protected line routed through the array and the return path kept as short as practical. This minimizes parasitic inductance during fast ESD events and helps keep the clamp action close to the entry point. Placement decisions should be based on the manufacturer datasheet and the actual board stack-up rather than assumed equivalent pin functions. A key design trade-off is capacitance versus protection capability: lower capacitance preserves signal integrity, but the device must still be checked against the required ESD and surge levels. The ESD1P0RFS-E6327 is best suited to applications where compact two-channel RF or high-speed-line protection is needed and the system’s operating voltages remain compatible with its 70 V reverse standoff rating. This page combines verified manufacturer and distributor information, strict package-aware substitution screening, and practical placement guidance. It distinguishes confirmed ratings from unavailable specifications and avoids presenting unverified electrical limits as product facts.
ESD1P0RFS-H6327 - RF ESD Protection Diode, 1pF, 20kV | Infineon
The Infineon ESD1P0RFS-H6327 is an RF ESD protection diode array housed in a 6-pin SOT-363 (SC-88) surface-mount package, designed for electrostatic discharge (ESD) and transient voltage suppression of radio-frequency antenna interfaces and ultra-high-speed data lines. Per the Infineon datasheet, this 2-channel array in unidirectional anti-parallel configuration provides ±20 kV contact ESD protection per IEC 61000-4-2, EFT immunity per IEC 61000-4-4, and surge immunity per IEC 61000-4-5 (8/20 µs), while exhibiting an ultra-low typical capacitance of 1 pF that preserves signal integrity at RF frequencies. The device clamps fast transients above approximately 15 V, with a 10 A peak pulse current capability (8/20 µs waveform) for surge events. The Schottky-diode-based silicon die is optimized to minimize insertion loss on 50 Ω transmission lines, making the part a clamp-and-release element rather than a series attenuator. An RF ESD protection diode is a specialized transient voltage suppressor (TVS) optimized for high-frequency signal paths, where the parasitic capacitance of a conventional TVS would distort the waveform and degrade return loss. In the broader component taxonomy, it sits beneath TVS diode -> ESD protection device -> circuit protection IC -> discrete semiconductor. Unlike general-purpose Zener-based TVS diodes used on DC power rails, RF ESD diodes target matched-impedance signal lines (USB, HDMI, GPS, LTE/Wi-Fi antennas) where capacitance must remain below a few picofarads to keep insertion loss below 0.5 dB. The 'H6327' suffix denotes Infineon's tape-and-reel packaging code (3,000 pcs/reel). Key features include a working breakdown voltage of approximately 70 V reverse standoff, low leakage current to preserve battery life in portable designs, and a compact SOT-363 footprint that occupies less than 9 mm² on the PCB, freeing board area for RF front-end components. The 2-channel configuration protects two signal lines simultaneously, which suits differential pairs and dual-antenna MIMO layouts without doubling the footprint. The unidirectional anti-parallel Schottky structure delivers symmetrical clamping on both polarities of the AC-coupled RF signal. The device integrates Infineon's silicon Schottky process technology, combining low forward voltage with sub-nanosecond response time, ensuring that ESD strikes from human-body or charged-device events are shunted to ground before downstream RF ICs (LNAs, mixers, transceivers) sustain damage. Unlike polymer or varistor-type suppressors, the silicon-based diode offers stable capacitance over voltage and temperature, which simplifies matching network design across the industrial temperature range. Typical applications include GPS antenna ESD protection, HDMI/DisplayPort interface protection, Wi-Fi/Bluetooth module antenna lines, LTE/5G RF front-end protection, USB 2.0/3.0 data line protection, and Ethernet PHY protection. When designing with this part, place it as close to the external connector as possible (within 3 mm of the ESD entry point) and provide a low-inductance ground return via multiple vias to the ground plane, otherwise residual inductance will raise the clamping voltage during fast transients.
ESD1P0RFW - 1 pF RF ESD Protection Diode | Infineon
The Infineon ESD1P0RFW is a 1 pF RF ESD protection diode with ±20 kV contact ESD immunity and 10 A surge compliance, supplied in a six-pin SOT-323 surface-mount package. Designed for RF antennas, GPS, HDMI, Ethernet, and other high-speed interfaces, it protects sensitive equipment from electrostatic discharge while minimizing signal-line loading. RF ESD protection is a specialized form of circuit protection used to shunt transient voltage away from low-voltage radio-frequency or high-speed interface circuitry. This device belongs to the TVS diode and surge-protection hierarchy, where fast, low-capacitance clamping preserves high-frequency signal integrity better than a conventional power TVS diode. The key feature is its ultra-low 1 pF typical line capacitance to ground, reported as 0.5 pF per diode. Low capacitance limits loading of RF and ultra-high-speed data lines while still providing transient protection. The device is specified for IEC 61000-4-2 contact discharge to 20 kV, IEC 61000-4-4 EFT at 40 A, and IEC 61000-4-5 surge at 10 A using the indicated pulse waveforms. The six-pin SOT-323 arrangement supports an anti-parallel protected signal-line configuration, as shown in the manufacturer application example. The diode structure can operate with superimposed DC voltage up to ±VF, but the exact forward-voltage and DC operating limits must be taken from the complete manufacturer datasheet before final circuit sign-off. Typical applications include GPS antenna inputs, RF antenna connectors, HDMI interfaces, Ethernet ports, and ultra-high-speed data lines. The low capacitance makes ESD1P0RFW most useful where transient suppression must be added without materially degrading signal bandwidth. Designers should place the protection device close to the connector or board entry point, route the protected signal on the protected side of the device, and verify that the package footprint and pin mapping match the PCB land pattern. Apply the manufacturer’s recommended layout and grounding practice to maximize surge-current handling and minimize parasitic inductance. This page combines verified Infineon specifications, distributor references, practical protection-layout guidance, and a strict assessment of drop-in alternatives. Because the supplied cross-reference data identifies no validated same-package substitute, no unverified replacement MPNs are presented.
ESD1P0RFW-E6327 - 1 pF 70 V RF TVS Diode | Infineon
The Infineon Technologies ESD1P0RFW-E6327 is a one-channel RF ESD-protection TVS diode with 1 pF typical capacitance, 70 V operating voltage, and a 15 V clamping voltage, supplied in the PG-SOT323 surface-mount package. Its low capacitance is intended to preserve high-frequency signal integrity while protecting RF antenna and interface lines. An RF ESD diode is a discrete transient-voltage suppressor optimized for high-frequency communication paths. Unlike a general-purpose high-capacitance TVS diode, this device places approximately 1 pF of loading on the protected line. In the broader device hierarchy, it is an ESD-protection diode, transient-voltage suppressor, discrete semiconductor, and circuit-protection component. The available data identifies ±20 kV contact ESD protection under IEC 61000-4-2, 40 A electrical-fast-transient compliance under IEC 61000-4-4, and 10 A surge compliance under IEC 61000-4-5 using an 8/20 microsecond waveform. The repetitive peak reverse voltage is 70 V, while distributor records report a 15 V clamping voltage. These ratings make the device suitable where both electrostatic discharge and transient filtering must be handled near exposed connectors. Infineon’s product information lists GPS, HDMI, and Ethernet among the target applications. In these systems, the diode is connected close to the entry point of the protected line so that surge energy is diverted before it reaches sensitive circuitry. The 1 pF capacitance limits high-frequency loading, while the low clamping voltage helps constrain the voltage presented to downstream devices. The E6327 ordering code is shown by DigiKey in the PG-SOT323 package. Related manufacturer variants appear in the same family, but the supplied cross-reference data does not establish enough verified information to present five distinct pin-compatible drop-in alternatives. Packaging codes and tape-and-reel variants were therefore not used as substitutes. For PCB implementation, place the protection device at the connector or antenna entry rather than near the protected receiver. Keep the transient-current path short and away from sensitive signal traces. Confirm that the line’s normal operating voltage remains below 70 V and that the downstream circuit can tolerate the specified 15 V clamp. This page combines verified manufacturer and distributor data with application guidance and explicitly identifies unavailable electrical details.
ESD1P0RFW-H6327 - RF ESD Protection Diode, 1pF, ±20kV | Infineon
The Infineon ESD1P0RFW-H6327 is a single-channel RF ESD protection diode optimized for high-frequency signal interfaces, housed in a 3-pin PG-SOT323 (SC-70) surface-mount package. It delivers ±20 kV contact / ±20 kV air ESD discharge protection per IEC 61000-4-2, with a peak surge current handling of 10 A (8/20 µs waveform) per IEC 61000-4-5 and EFT immunity per IEC 61000-4-4. The diode exhibits a typical capacitance of 1 pF and a maximum reverse standoff of 70 V, making it ideal for RF antenna lines where ultra-low loading capacitance preserves signal integrity up to multi-GHz frequencies. An ESD protection diode is a specialized transient voltage suppressor (TVS) designed to clamp fast electrostatic discharge events to safe levels, preventing damage to downstream ICs. In the broader component taxonomy, the ESD1P0RFW-H6327 belongs to TVS diodes -> ESD protection devices -> circuit protection -> discrete semiconductors. Unlike general-purpose TVS diodes, RF-class ESD devices are characterized by extremely low junction capacitance (typically <2 pF) so they do not attenuate the high-frequency content of RF signals, GPS L1/L2, HDMI TMDS, or 2.4 GHz / 5 GHz Wi-Fi paths. Key features include an ultra-low 1 pF typical line capacitance, ±20 kV ESD contact rating, 10 A peak surge handling (8/20 µs), a 70 V maximum reverse standoff voltage, and an integrated silicon-based TVS structure in a compact PG-SOT323 footprint. The device operates across the industrial -55 °C to +150 °C temperature range and is rated for lead-free reflow profiles up to 260 °C peak. The silicon-based TVS structure uses a steering-diode/fast-clamp topology where the diode forward biases during negative ESD events and avalanches during positive transients, shunting energy to ground with sub-nanosecond response. The 1 pF capacitance is achieved by minimizing the die junction area while maintaining the 10 A surge capability, a trade-off that yields adequate power rating for portable RF equipment without introducing measurable insertion loss below 3 GHz. Typical applications include GPS antenna ESD protection, HDMI TMDS lines, 10/100/1000 Ethernet ports, USB 2.0 data lines, mobile phone RF modules, and other ultra-high-speed data interfaces where capacitive loading must be minimized to preserve signal integrity. When designing with this diode, place it as close as possible to the external connector with a short, low-inductance ground return to the chassis or PCB ground plane. Do not place series ferrite beads ahead of the ESD diode because residual inductance at the diode's cathode limits clamping effectiveness for sub-nanosecond ESD events. This page synthesizes distributor pricing, drop-in alternates, and practical design notes not found in the manufacturer datasheet alone.
ESD204DQAR - Quad 0.55pF ±3.6V ESD TVS Diode | Texas Instruments
The Texas Instruments ESD204DQAR is a quad-channel bidirectional TVS ESD protection diode array with 0.55 pF channel capacitance, ±3.6 V operating voltage, and 5.5 A (8/20 µs) surge capability, housed in a 10-USON (2.5 mm x 1 mm) surface-mount package. A TVS (transient voltage suppressor) ESD protection diode is a clamping device placed on sensitive signal lines to divert electrostatic-discharge and cable-surge energy away from downstream ICs. Within the power and signal-integrity hierarchy, it belongs to the TVS diode family, which sits under surge protectors, a subset of circuit-protection components. Arrays such as the ESD204 protect multiple lines simultaneously, which is essential for differential interfaces like USB and HDMI where paired lines must be clamped symmetrically to preserve signal balance. Key features of the ESD204DQAR include ultra-low 0.55 pF junction capacitance, which minimizes signal-eye degradation on multi-gigabit links; ±30 kV ESD contact and air-gap robustness per IEC 61000-4-2 Level 4; a low clamping voltage of approximately 11.5 V (typical) at surge current; and bidirectional construction, so no polarity concerns arise on AC-coupled or differential lines. Architecturally, the four bidirectional TVS channels share a common reference, and the flow-through 10-USON footprint lets traces pass straight through the device, reducing stub length and impedance discontinuity. This flow-through routing is one reason the part is favored on HDMI and USB ports where every millimeter of stub affects the eye diagram at 480 Mbps and beyond. Typical applications include USB 2.0 port protection, HDMI 1.4 interface clamping, and general-purpose high-speed differential or single-ended line protection on industrial and consumer boards. Its low capacitance and low clamping voltage make it a natural fit wherever a designer must protect a port without visibly closing the signal eye. Design-wise, keep the ESD204DQAR within 5 mm of the connector and place it before any downstream series elements; the ground return path to the board plane should be short and wide to keep the clamping loop inductance low during an 8/20 µs surge. This page adds value beyond the manufacturer datasheet by consolidating distributor pricing, drop-in alternative analysis, and practical layout guidance in one place.
ESD24VS2 - 26V ESD Protection TVS Diode | Infineon
The Infineon Technologies ESD24VS2 is an ESD protection and TVS diode in the PG-SOT23 surface-mount package. Verified distributor data identifies it as a silicon TVS protection device with a 26 V nominal protection voltage and automotive ESD/EMI protection capability, while the related automotive ordering code ESD24VS2UE6327HTSA1 is listed at DigiKey with a 41 V clamp at 5 A for an 8/20 microsecond pulse. ESD24VS2 is therefore intended for protecting sensitive electronic circuits from electrostatic discharge and transient voltage events. A TVS diode, also called a transient-voltage-suppression diode, is a discrete semiconductor protection device. It belongs to the diode and surge-protection hierarchy, sits between a protected circuit node and ground or a supply rail, and diverts transient current when the voltage rises beyond its protection threshold. The device acts as a high-impedance path during normal operation and becomes conductive during a short ESD pulse. This category complements other circuit-protection methods such as filters, fuses, and overvoltage clamps. Verified listings describe the ESD24VS2 family for ESD and EMI protection, automotive applications, and 30 kV ESD withstand in the ESD24VS2U E6327 ordering variant. The supplied data does not establish the complete electrical rating set for the exact base MPN, so details such as reverse working voltage, breakdown voltage, forward voltage, capacitance, leakage current, and pulse power are retained as data-needed values rather than inferred from related variants. The PG-SOT23 package supports compact surface-mount layouts and is commonly used on signal lines, control interfaces, communication ports, and low-voltage equipment. Placement near a connector or board entry point helps limit transient energy before it reaches sensitive circuitry. The exact package pin mapping is not published in the supplied verification excerpt, so the package pinout is marked unavailable rather than guessed. Use ESD24VS2 when the board requires a dedicated discrete ESD clamp and the verified protection rating meets the system’s interface threat level. Designers should confirm the exact ordering variant, polarity, working voltage, clamp voltage, and system grounding strategy against the manufacturer datasheet before production release. This page consolidates the supplied distributor references, datasheet link, and circuit-protection guidance without inventing missing ratings. The most important design tradeoff is between placing the clamp close to the connector and controlling capacitance or leakage on sensitive signal paths. For power or high-current transients, the TVS diode may require a separate fuse or upstream surge-protection stage; the supplied data does not establish suitability for those conditions. This device should be selected for ESD and EMI transients rather than assumed to replace a power surge suppressor. This product page combines verified Infineon and distributor references, practical placement guidance, application context, and strict data-gap markers. It is intended as an engineering starting point for ESD protection selection, with final approval dependent on the exact variant datasheet and system-level transient validation.
ESD2CAN24DBZRQ1 - 24V 3pF 30kV Automotive TVS | TI
The Texas Instruments ESD2CAN24DBZRQ1 is an automotive dual 3 pF bidirectional ESD protection diode rated for ±24 V and ±30 kV ESD events, packaged in a 3-pin SOT-23 (DBZ) surface-mount package. It is designed for Controller Area Network (CAN) transceivers and other in-vehicle network lines where low capacitance, low clamping voltage, and robust transient protection are required. A TVS diode, also called a transient-voltage suppressor, is a protection component that diverts short high-voltage pulses away from sensitive circuitry. Automotive CAN links are particularly vulnerable because external wiring can receive electrostatic discharge and transient events. The ESD2CAN24-Q1 family is positioned at the interface boundary, helping protect the connected transceiver without materially loading the data line. The device provides two protected channels in a compact SOT-23 package. Its typical capacitance is 3 pF, helping preserve the high-speed edge behavior expected by automotive digital interfaces. The protection rating is specified as ±30 kV ESD, while the verified product information also identifies an ISO 10605 capability of ±27 kV contact and ±27 kV air-gap discharge. Its bidirectional structure supports protection against either transient polarity on the protected lines. The ESD2CAN24DBZRQ1 is identified as an automotive TVS and is associated with AEC-Q101 qualification in the verified product and cross-reference information. The operating temperature range reported by the verified source is −55 °C to +150 °C. The DBZ package is intended for surface-mount assembly, and the RQ1 ordering suffix identifies the automotive-qualified product variant. A typical clamp condition is 37 V, with 5.7 A peak pulse current for an 8/20 microsecond pulse. Use this device on CAN transceiver inputs or other automotive network connections after confirming signal polarity, line impedance, trace geometry, and the protection current path. Its 3 pF capacitance is suitable for low-capacitance protection, but PCB placement and grounding remain important for effective transient diversion. The protector should be placed close to the connector or entry point, with short, low-inductance connections to the protected circuitry. This page combines verified manufacturer and distributor information with practical protection guidance, comparison information, and application-oriented design notes. It is intended to help engineers identify the correct automotive ESD-protection footprint, verify ratings, and plan PCB implementation without assuming parameters that are not present in the supplied data.
ESD2CAN24DCKRQ1 - 24V Dual CAN Bus ESD Protection | TI
The Texas Instruments ESD2CAN24DCKRQ1 is an automotive-grade, bidirectional, dual-channel ESD protection TVS diode rated at +/-24 V working voltage with 3 pF typical line capacitance, +/-30 kV system-level ESD robustness, and a 5.7 A (8/20 us) Ipp surge rating, housed in a 3-pin SC-70 (SOT-323, DCK) surface-mount package. An ESD protection diode (also called a TVS diode or transient voltage suppressor) is a discrete semiconductor protection device that clamps electrostatic discharge and cable-transient events to a safe level before they reach sensitive transceiver pins. Within the system hierarchy, it sits in the circuit-protection layer of a network interface, upstream of components such as CAN transceivers, microcontrollers, and automotive MCUs, forming part of the broader power and signal integrity chain defined by ISO 10605 and IEC 61000-4-2 test environments. Key features include a low dynamic resistance that produces a low clamping voltage (37 V typical under surge), a back-to-back TVS structure supporting bidirectional signaling on both CAN_H and CAN_L, and AEC-Q100 automotive qualification with a -55C to +150C junction temperature range. Per the TI datasheet (ESD2CANxx24-Q1, Rev. D), the device dissipates contact ESD strikes beyond the maximum level specified in ISO 10605: +/-27 kV contact and +/-27 kV air-gap. The architecture uses two bidirectional ESD structures with an integrated clamp circuit, giving a 3 pF typical / 5 pF maximum line capacitance that preserves the 5 Mbps CAN FD signal margin while the low clamping voltage protects downstream transceivers against transient events on the bus. Typical applications include 12 V and 24 V automotive CAN and CAN FD bus protection, in-vehicle network gateways and body-control modules, and industrial CAN fieldbus nodes where robustness against coupled transients is required. Design consideration: place the diode as close as possible to the connector, with a short, direct ground return; excessive trace inductance ahead of the diode degrades the effective clamping voltage during a fast ESD event. This page adds value beyond the datasheet by synthesizing drop-in-alternative analysis, package comparison, and practical layout guidance from the TI E2E interface forum and distributor listings in one place.
ESD351DPYR - 30kV ESD Protection Diode, 0.1 Ohm | TI
The Texas Instruments ESD351DPYR is a 1-channel uni-directional TVS ESD protection diode rated for 30 kV ESD strikes (contact and air) per IEC 61000-4-2, featuring an ultra-low 0.1 ohm dynamic resistance, 6.5 V clamping voltage at 16 A TLP, and 1.8 pF junction capacitance in a 2-pin X1SON (DPY, 0402 footprint) package. An ESD protection diode, also called a TVS (transient voltage suppressor) diode, is a semiconductor device that diverts fast electrostatic discharge and surge events away from sensitive ICs. It sits at the bottom of the circuit-protection hierarchy - below board-level surge suppressors and above nothing - acting as the last line of defense on high-speed signal lines. ESD protection devices are classified as discrete semiconductors within the broader TVS and surge protection category. Key differentiating features of the ESD351 include the 0.1 ohm dynamic resistance, which is among the lowest available for a 0402-package ESD diode, delivering extremely low clamping voltage during a real IEC 61000-4-2 strike. The 1.8 pF line capacitance preserves signal integrity on high-speed interfaces, and the 3.3 V operating voltage suits modern low-voltage rails. Technically, the ESD351 uses a snap-back-free deep-trench process that minimizes parasitic inductance and capacitance. The low R_DYN means the on-state voltage rise during a 16 A TLP event is only about 0.65 V above the breakdown knee, keeping residual clamp energy - and therefore IC stress - very low. This is critical because system-level ESD survivability correlates strongly with residual clamping voltage, not datasheet breakdown voltage alone. Typical applications include USB 2.0 port protection, high-speed digital I/O on portable and wearable devices, and antenna or RF front-end line protection where capacitance must stay low. Design consideration: place the ESD351DPYR within a few millimeters of the connector, before any series termination resistors, so the strike current is diverted at the board edge; every millimeter of trace adds inductance that raises effective clamping voltage. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
ESD451DPLR - 0.5pF ±30kV ESD Diode | Texas Instruments
The Texas Instruments ESD451DPLR is a single-channel bidirectional electrostatic-discharge protection diode rated for ±30kV IEC 61000-4-2 strikes, with 0.5pF typical I/O capacitance and a 5.5V working-voltage rating. It is supplied in the compact 2-X2SON 0.6mm × 0.3mm package identified by the DPLR ordering code. The device is intended to protect high-speed data lines and other I/O ports without imposing substantial signal loading. A TVS diode, or transient-voltage-suppression diode, is a semiconductor protection component that diverts short-duration electrostatic-discharge energy away from a sensitive circuit. A bidirectional ESD diode provides symmetric protection for positive and negative transients. In the protection hierarchy, ESD451DPLR belongs to the discrete-semiconductor category and is used at connector or board-edge interfaces where electrostatic discharge can damage low-voltage ICs. Verified manufacturer and distributor data identify ±30kV IEC 61000-4-2 protection, 0.5pF typical I/O capacitance, and suitability for high-speed interfaces including USB 3.0. The low capacitance helps preserve fast-edge data transmission, while bidirectional conduction supports protection of signal conductors that may experience either transient polarity. The 5.5V rating and 9.5V typical clamp voltage are important when choosing the correct protection location and ensuring that normal signal operation is not affected. The extremely low dynamic resistance is identified by the manufacturer as 0.19Ω in the supplied product-page snippet. This low resistance helps reduce voltage stress during an ESD event. The device is designed for surface-mount assembly and is available through distributors such as DigiKey, Mouser, LCSC, and Xecor. Distributor listings describe the part as a TVS diode with a 6A 8/20µs peak-pulse current rating, although the complete electrical test conditions should be taken from the manufacturer datasheet. Typical uses include USB 3.0 ports, high-speed serial interfaces, audio and communication connectors, and other low-voltage I/O ports exposed to electrostatic discharge. The compact footprint is advantageous in mobile, wearable, and space-constrained equipment, but placement requires close proximity to the connector or entry point so that the ESD current does not travel through unprotected PCB traces. When designing around ESD451DPLR, first verify that the protected line operates below the device's stated working-voltage limit and that its signal integrity is compatible with 0.5pF typical capacitance. Place the diode close to the external connector, route the protected trace away from sensitive areas, and provide a short return path. Validate the completed design with the applicable system-level ESD test rather than assuming that a single component guarantees compliance. This page combines verified manufacturer specifications, distributor availability information, drop-in replacement research, and PCB-level protection guidance to provide a practical engineering reference for ESD451DPLR selection and implementation.
