TJ60S06M3L(T6L1,NQ - 60V 60A P-Ch MOSFET DPAK+ | Toshiba
The Toshiba TJ60S06M3L(T6L1,NQ is a P-channel silicon power MOSFET rated at -60 V VDS, -60 A continuous drain current, and 100 W power dissipation, housed in a surface-mount DPAK+ (TO-252-3) package. Built on Toshiba's U-MOS process, it delivers a typical on-resistance of 11.2 mOhm at VGS = -10 V and a typical threshold voltage of -3.0 V, achieving a figure of merit that suits high-current switching applications. The device is qualified to AEC-Q101 for automotive reliability. A P-channel MOSFET (P-FET) is a type of metal-oxide-semiconductor field-effect transistor in which the body-source p-n junction is reversed-biased and majority-carrier conduction is by holes rather than electrons. P-channel MOSFETs belong to the broader category of power MOSFETs (MOSFET -> discrete semiconductor -> power transistor), and they occupy a unique role in high-side switching because their source sits at the load supply rail, simplifying gate drive when the load must be switched to ground. P-FETs are commonly used as reverse-polarity protection devices, high-side load switches, and synchronous-rectifier replacements in low-voltage buck converters. Key features of the TJ60S06M3L include a maximum drain-source on-resistance RDS(ON) of 14.5 mOhm at VGS = -10 V, a low input capacitance Ciss of 7760 pF that keeps gate-drive losses manageable, and an enhancement-mode threshold that allows direct logic-level gate drive from -3.3 V or -5 V microcontrollers. The DPAK+ tab provides a low-thermal-resistance path (junction-to-case) suitable for continuous high-current operation with modest PCB copper area. The architecture uses Toshiba's latest-generation U-MOS trench cell, which lowers specific on-resistance versus older planar P-FET generations, and integrated gate-protection circuitry to limit avalanche energy. Compared with a mechanical relay, the MOSFET offers silent, fast (<50 ns half-controlled) switching and zero contact bounce, while compared with a PNP bipolar transistor it eliminates base-drive current and the saturation-voltage knee. Typical applications for this part include automotive reverse-battery protection, DC-DC converter high-side switches, motor-driver H-bridges (low-side or high-side position), and switching voltage regulators in industrial power systems. Because of its 60 V rating it can replace mechanical relays in 24 V and 48 V automotive and industrial buses. Design tip: when using the TJ60S06M3L as a reverse-polarity protection FET, ensure that the gate is pulled to ground through a resistor when the system is off; floating gates can leave the FET in an undefined state and create leakage paths. Also note that the AEC-Q101 grade makes this part suitable for under-hood automotive designs where ambient temperatures can reach 125 C.
TJ60S06M3L(T6L1,NQ - P-Ch -60V -60A 11.2mOhm DPAK+ MOSFET | Toshiba
The Toshiba TJ60S06M3L(T6L1,NQ is a P-channel silicon power MOSFET built on Toshiba's U-MOS process, rated for -60 V VDS, -60 A continuous drain current (TC), and a maximum power dissipation of 100 W. Housed in a surface-mount DPAK+ (TO-252 with extended leads) package, it delivers an ultra-low on-resistance of 0.0112 ohm at VGS = -10 V, with an input capacitance (Ciss) of 7760 pF. A P-channel MOSFET is a voltage-controlled field-effect transistor in which the conductive channel is formed by holes rather than electrons. Because P-channel devices turn on with a negative gate-source voltage, they simplify high-side switching in circuits where the load is tied to ground - no charge pump or bootstrap network is needed to drive the gate. P-channel MOSFETs are typically placed in the power-MOSFET hierarchy under 'P-channel -> MOSFET -> power MOSFET -> discrete semiconductor' and are widely used as reverse-polarity protection, high-side load switches, and synchronous-rectifier complements in DC-DC converters. Key features of the TJ60S06M3L include the very low 11.2 milliohm Rds(on) at full gate drive, the -60 V drain rating that provides substantial avalanche headroom for 12 V / 24 V automotive buses, and an industry-standard DPAK+ footprint that allows direct PCB mounting with a thermal pad for low thermal resistance. The part is qualified for automotive motor drivers, DC-DC converters, and switching voltage regulators per Toshiba's product family positioning. Technically, the device uses Toshiba's latest-generation U-MOS trench cell structure to achieve a per-cell figure-of-merit (FOM = Rds(on) x Qg) optimized for switching loss reduction. This makes it particularly suitable for hard-switched applications up to several hundred kHz where switching losses dominate conduction losses. The P-channel polarity allows direct logic-level driving from standard microcontrollers without additional gate-driver circuitry. Typical applications include automotive ECU load switching, motor-driver H-bridge high-side switches, battery management system (BMS) reverse-polarity protection, synchronous-rectifier secondary-side switches in isolated DC-DC converters, and high-current load management in industrial 24 V systems. The DPAK+ package's exposed thermal pad allows direct PCB heatsinking. When designing with this device, mind the gate-source voltage rating of +10 V / -20 V - the absolute maximum must not be exceeded even during transients. Use a gate-source resistor (typically 10 kohm) to prevent inadvertent turn-on from Miller-coupling during drain-voltage transients. Verify continuous drain current against your thermal envelope using the SOA curve from the manufacturer datasheet. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet alone, providing a single reference for sourcing and second-sourcing the TJ60S06M3L(T6L1,NQ.
TL431AIDBVR - 2.495V-36V Adjustable Shunt Reference, 1% | Texas Instruments
The Texas Instruments TL431AIDBVR is a precision adjustable shunt voltage reference that delivers a programmable output from 2.495V to 36V with a 1% initial tolerance (A grade) in a 5-pin SOT-23 (DBV) package. It provides up to 100 mA of cathode current with low dynamic impedance of 0.2 ohm typical, making it functionally equivalent to a non-isolated Zener diode but with tighter tolerance and adjustable setpoint. A shunt voltage reference is a two-terminal (plus reference pin) device that maintains a constant voltage across its terminals by shunting excess current to ground, analogous to a Zener diode but with programmable breakdown voltage. Shunt references form a sub-category of voltage references within the broader voltage regulator hierarchy (voltage reference -> shunt regulator -> analog reference circuit -> signal chain IC), and they are foundational building blocks for power supply feedback, ADC reference rails, comparator thresholds, and error amplifiers in isolated and non-isolated converter topologies. Key features of the TL431AIDBVR include a 2.495V reference voltage (Vref) with 1% initial accuracy at 25C, an operating cathode current range of 1 mA to 100 mA, typical dynamic impedance of 0.2 ohm at 1 kHz, and an operating temperature range of -40C to +85C. The SOT-23-5 surface-mount package offers a compact footprint while exposing the reference, anode, and cathode pins in a standardized layout used industry-wide across second-source vendors. The TL431 architecture uses a buried-Zener bandgap reference cell feeding an on-chip op-amp that drives a pass transistor, producing a sharp knee in the I-V curve and excellent thermal stability. According to the manufacturer datasheet, the device exhibits typical output impedance of 0.2 ohm over 1 kHz and a wideband noise figure suitable for switch-mode power supply feedback loops and audio threshold detection. Typical applications include SMPS secondary-side regulation, isolated flyback error amplifier reference, adjustable Zener replacement, voltage monitoring and reset circuits, and precision current limiting. The SOT-23-5 form factor is well suited for high-density DC-DC converter boards and compact adapter designs. When designing with the TL431AIDBVR, ensure the cathode current stays between 1 mA and 100 mA across all load and line conditions, including start-up transients. Place the device close to the opto-coupler or error-amplifier input to minimize loop-area noise pickup, and use a bypass capacitor on the reference pin if the application requires low AC noise.

TL431AIDBVRG4 - 2.495V Adjustable Shunt Reference | Texas Instruments
The Texas Instruments TL431AIDBVRG4 is a precision programmable shunt voltage reference IC with an adjustable output of 2.495 V to 36 V, ±1% initial accuracy, and 100 mA cathode current capability, housed in a 5-pin SOT-23 (DBV) package. It belongs to the TL431 family of three-terminal adjustable shunt regulators specified for operation from -40°C to 85°C, with the G4 suffix marking the lead-free, RoHS-compliant, tape-and-reel packaging option. A shunt voltage reference is a two-terminal (or three-terminal with adjustment) device that maintains a constant voltage across its terminals by sinking varying amounts of current through a parallel load. Shunt references sit at the same hierarchy level as series (bandgap) references, but are wired in parallel with the load rather than in series — making them functionally closer to a Zener diode than to a LDO regulator. The TL431 family implements an adjustable bandgap core with an on-chip op-amp and reference network, allowing the user to set the output via an external resistor divider. Key features include a typical output impedance of 0.2 Ω at low frequencies, a low output noise of approximately 0.2 µV_RMS across the audio band, and a temperature coefficient of 109 ppm/°C (max). The device sinks from 1 mA (minimum cathode current for regulation) up to 100 mA continuously, with absolute-maximum cathode voltage of 37 V. The SOT-23-5 footprint offers a compact land pattern of approximately 2.9 mm × 1.6 mm, suiting it to high-density switching supply and isolated feedback designs. The TL431 architecture pairs a precision bandgap reference with a transconductance error amplifier driving an open-collector pass transistor. When the divided output drops below the internal 2.495 V bandgap, the amplifier reduces cathode conduction, raising V_OUT; when it rises above, conduction increases, clamping V_OUT. This feedback loop yields tight line and load regulation in closed-loop SMPS optocoupler and primary-side feedback circuits. Typical applications include isolated DC-DC converter secondary-side regulation, switch-mode power supply (SMPS) feedback loops, adjustable Zener replacement, voltage monitoring, and precision comparator thresholds. Its wide cathode voltage range makes it ideal for 3.3 V, 5 V, 12 V, and 24 V rails. The combination of small SOT-23 footprint and high accuracy is particularly valuable in industrial PSU designs with tight PCB constraints. When designing with this part, ensure the cathode current stays between 1 mA and 100 mA under all load and line conditions. Add a 0.1 µF bypass capacitor close to the cathode pin when the device operates in fast-loop SMPS feedback paths to suppress transient oscillation. Choose resistors in the divider for low standby current, and ensure the divider current is at least 100× the TL431 reference bias current for accuracy.

TL431ASA-7 - Adjustable Shunt Regulator 36V 1% SOT-23-3 | Diodes Inc.
The Diodes Incorporated TL431ASA-7 is an adjustable precision shunt voltage reference regulator with a 2.495V bandgap reference, ±1% initial tolerance, adjustable output range up to 36V, and 100mA cathode current capability in a 3-pin SOT-23 (SOT-23-3) surface-mount package. An adjustable shunt regulator is a three-terminal voltage reference device that maintains a precise voltage across its cathode and anode terminals by shunting excess current, controlled by an external resistor divider connected to the reference pin. In the power-management hierarchy, it sits below switching regulators and linear regulators as the precision building block used to set feedback thresholds, and it is one of the most widely used reference ICs in the industry, with the TL431 function being a de-facto industry standard footprint. Key features of the TL431ASA-7 include the ±1% initial reference accuracy of the A-grade die, a temperature-compensated bandgap reference, and a low dynamic output impedance. According to the Diodes Incorporated datasheet, the TL431 series has the same electrical specifications as the industry-standard '431 and is offered in A (1%) and B (0.5%) accuracy grades. The device operates as either a shunt regulator or an open-collector comparator with a 2.495V threshold, giving engineers two functions in one package. Technically, the part uses an internal bandgap reference and an output amplifier driving a shunt transistor. When the reference pin voltage exceeds 2.495V, the device sinks current from cathode to anode, holding the reference pin at 2.495V. With two external resistors the output is programmable from 2.495V up to 36V. The primary use case is as the error amplifier and reference in the feedback loop of flyback and buck switching power supplies, optocoupler-coupled feedback networks, and precision comparators. Typical applications include SMPS feedback regulation, battery chargers, adjustable zener replacement, voltage monitoring thresholds, and constant-current source circuits. Its low cost and small SOT-23-3 footprint make it suitable for both industrial and consumer designs. A key design consideration is ensuring the cathode current stays above the minimum regulation level (typically ~1mA region) across load and temperature for guaranteed regulation, and choosing divider resistor values that balance accuracy against quiescent loading.

TL431BFDT - Adjustable Shunt Regulator 2.495-36V SOT-23 | Nexperia
The Nexperia TL431BFDT is a three-terminal adjustable precision shunt voltage regulator with a reference voltage of 2.495 V, an adjustable output range from 2.495 V to 36 V set by two external resistors, and a cathode current capability up to 100 mA, housed in a 3-pin SOT-23 (TO-236AB) surface-mount package. A shunt regulator (also called a shunt voltage reference) is a type of voltage regulator that maintains a set voltage across its terminals by sinking or sourcing current in parallel with the load. Unlike a series regulator, the shunt topology sits across the supply path and absorbs surplus current, making it the workhorse of the voltage reference family within power management and discrete semiconductor hierarchies. The TL431 is the industry-standard part of this class, widely used in isolated and non-isolated power supplies. The TL431BFDT offers a tight B-grade reference tolerance of +/-0.5% at 25 C, an operating temperature range of -40 C to +125 C (Q-grade qualification per Nexperia automotive designation), and enhanced stability with a very low minimum load capacitance requirement in the FDT variant family. According to the Nexperia product page, the family covers reference tolerances from 2.0% down to 0.5% and temperature ranges up to 125 C, with AEC-Q100 qualification noted for automotive use. Architecturally, the device integrates a 2.495 V bandgap reference, an error amplifier, and an open-collector output transistor. When the voltage at the REF pin exceeds the internal reference, the output transistor conducts cathode current, regulating the cathode voltage in closed-loop configurations such as optocoupler feedback in flyback converters. Typical applications include secondary-side feedback regulation in AC-DC adapters and flyback SMPS, adjustable voltage references in battery chargers, overvoltage protection crowbars, and setpoint generation in LED drivers. Design-wise, provide a minimum cathode bias current (about 1 mA) for regulation and add a small compensation capacitor at REF for loop stability in optocoupler feedback paths.

TL431CDBZR - Adjustable 2.495V Shunt Reference 100mA SOT-23-3 | TI
The Texas Instruments TL431CDBZR is a three-terminal adjustable precision shunt voltage reference IC with a programmable output range of 2.495 V to 36 V, up to 100 mA sink current capability, and ±2.2% initial reference tolerance, housed in a 3-pin SOT-23 (DBZ) surface-mount package. An adjustable shunt regulator (also called a programmable shunt reference) is a type of voltage reference IC that regulates voltage by sinking current from a supply rail through its cathode when the reference pin senses a voltage above an internal bandgap threshold. In the power-management hierarchy, it sits between a fixed zener diode and a full linear regulator: more precise and temperature-stable than a zener, yet far cheaper and simpler than an LDO. Because the output is set by just two external resistors, the shunt reference family is a fundamental building block in analog circuit design. Key features include a wide adjustable output range set by two external resistors, approximately 2.495 V internal reference with 2.2% (standard C grade) initial tolerance, 0.2 ohm to 0.5 ohm order typical dynamic output impedance, and a maximum cathode current of 100 mA. The C-grade device is specified over the 0 C to 70 C commercial temperature range, and its low minimum cathode current of roughly 1 mA allows operation in low-power systems. Technically, the TL431 combines an internal 2.495 V bandgap reference with an operational amplifier and an open-collector output transistor. When the REF pin exceeds the internal threshold, the output transistor conducts and sinks current from cathode to anode, forming the basis of error-amplifier action in isolated flyback and forward power supplies, where the TL431 is frequently paired with an optocoupler such as the PC817 for secondary-side feedback. Typical applications include secondary-side voltage regulation and feedback in AC-DC and DC-DC switch-mode power supplies, adjustable zener replacement and overvoltage crowbar sensing, battery charger voltage monitoring, and precision threshold comparators in industrial instrumentation. A critical design consideration is temperature drift: the C grade (2.2% at 25 C) drifts more than the A or B grades over temperature, so precision systems should select TL431ACDBZR or TL431BDBZR instead. Always provide at least the minimum cathode current for regulation. This page adds distributor pricing, drop-in alternatives, and practical design notes not found in the manufacturer datasheet.
TL431ILPR - Adjustable 2.495V Shunt Reference | TI
The Texas Instruments TL431ILPR is a three-terminal adjustable precision shunt regulator with a 2.495V reference voltage, up to 100mA sink-current capability, and cathode voltage operation to 36V, housed in a 3-pin TO-92 (LP) through-hole package supplied on tape and reel. According to TI, the standard grade TL431I offers an initial reference tolerance of 2% at 25C. An adjustable shunt regulator is a type of voltage reference IC that maintains a programmed voltage across its cathode-anode terminals by sinking current when the sense voltage at its reference pin exceeds an internal bandgap threshold. Within the power-management hierarchy it sits below linear regulators as a precision reference element, and it is widely used as the feedback error amplifier inside isolated and non-isolated switching power supplies. Key features of the TL431ILPR include a programmable output voltage set anywhere from Vref (approximately 2.5V) to 36V using just two external resistors, a sharp low-dynamic-output-impedance characteristic, low output noise, and a typical temperature coefficient in the low ppm/C range across the specified -40C to +85C industrial operating range. Its 1mA to 100mA sink-current range gives designers wide loop-gain control in optocoupler feedback networks. Technically, the TL431 combines an internal 2.495V bandgap reference with an open-collector-style error amplifier driving the cathode output. Because the reference input draws only about 2uA typical, high-impedance divider networks are practical. The device is stable with appropriate capacitive loading per the stability boundary in the manufacturer datasheet, and it is specified for thermal stability over automotive, commercial, and military temperature grades across the family. Typical applications include secondary-side voltage regulation in flyback and forward AC-DC power supplies, adjustable zener replacement in overvoltage protection Crowbar circuits, precision current-source and current-limiter biasing, and set-point generation in battery chargers. Its three-pin simplicity and low cost make it the industry default feedback element driving optocoupler LEDs in isolated converters. Design-wise, keep the cathode current above the 1mA minimum for regulation and respect the datasheet stability criteria when adding decoupling capacitance at the cathode node; the compensation capacitor interacts with the equivalent series resistance in ways that can destabilize the loop.

TLP183(GB-TPL,E - 3750Vrms Phototransistor Optocoupler SO6
The Toshiba TLP183(GB-TPL,E is a 4-pin SO6 phototransistor optocoupler providing 3750 Vrms isolation voltage, DC input, and a current transfer ratio (CTR) rank of GB (100% to 300% at IF=5 mA). It is housed in a miniature 6-SOP surface-mount package (Toshiba designation 4-pin SO6) that combines a high-emission infrared LED with a phototransistor detector optically coupled in a plastic DIP-style body. A phototransistor optocoupler is a galvanic isolation device that transfers an electrical signal between two circuits using light, blocking high voltages and transient surges while transmitting the analog or digital signal at the speed of the photodetector. Within the broader component taxonomy, the TLP183 belongs to optoisolators > optocouplers > solid-state relays > isolators > discrete semiconductors, with the phototransistor output placing it in the same family as the Toshiba TLP181, TLP185 and TLP184 series. Key features include 3750 Vrms minimum isolation voltage, 50 mA maximum forward current, 80 V collector-emitter breakdown voltage, 50 mA collector current, and an operating temperature range of -55C to +110C. The GB CTR rank provides 100% to 300% typical transfer ratio at IF=5 mA and VCE=5 V, which is well suited to digital signal isolation in PLCs and communication interfaces. A GaAs infrared LED emitter delivers fast switching with rise/fall times measured in microseconds. The TLP183 employs a high-isolation optically-coupled architecture: the input-side GaAs LED converts the input current into modulated infrared light that crosses an internal transparent isolation barrier, after which a silicon phototransistor converts the light back into a current at the output side. The result is complete electrical isolation between input and output while preserving the timing and amplitude characteristics of the original signal. Typical applications include PLC digital input/output isolation, communication interface isolation (RS-232, RS-485 line-side isolation), power supply feedback loops, and AC mains detection circuits where 3750 Vrms isolation is required by safety standards. The wide -55C to +110C temperature range also supports industrial and consumer-grade equipment. When designing with the TLP183, ensure that the bias resistor on the LED side limits the forward current to within 50 mA DC, and that the collector pull-up resistor is sized according to the desired switching speed and the chosen CTR rank. Proper creepage and clearance around the SO6 body must be maintained to preserve the 3750 Vrms isolation rating in end-equipment safety certification.

TLV431IDBVR - 1.5% 6V Adj Shunt Reference | Texas Instruments
The Texas Instruments TLV431IDBVR is a low-voltage three-terminal adjustable precision shunt regulator providing a 1.24 V reference with ±1.5% initial accuracy and 15 mA maximum cathode current, housed in a 5-pin SOT-23 (DBV) package. Output voltage is programmable from VREF (1.24 V) to 6 V through two external resistors, enabling flexible rail design from sub-1.5 V point-of-load references up to small analog and digital supplies. The low minimum cathode current of 80 µA (typical) makes the part well suited to low-power and always-on circuits. A shunt voltage reference such as the TLV431 is functionally a two-terminal analog building block - when biased with a resistor from a higher supply, it conducts current through its cathode-to-anode path to hold its reference pin at the programmed voltage. As a category, voltage references sit alongside linear regulators, supervisors, and ADC/DAC references inside the power management IC hierarchy, and behave as programmable Zener diodes with much tighter tolerance and lower dynamic impedance than discrete components. They are the building blocks of closed-loop SMPS feedback, precision comparators, and adjustable linear regulators. Key features of the TLV431 family include 1.24 V typical reference with ±1.5% tolerance (the tighter TLV431A grade specifies ±1%), a wide programmable output range of VREF to 6 V, 80 µA typical minimum cathode current, low output impedance of 0.25 Ω typical, and operation across -40 °C to +85 °C industrial/commercial temperatures. The 5-pin SOT-23 (DBV) footprint enables drop-in replacement among TLV431 grades and competitor parts in the same pin-out. Architecturally, the TLV431 uses a bandgap-derived 1.24 V reference buffer, an internal error amplifier that compares the reference pin to VREF, and a pass transistor that sinks current to regulate the output. The wide cathode operating range and low dynamic impedance allow the regulator to maintain tight output regulation across load and supply variations typical of switching-supply feedback loops. Typical applications include switching-supply secondary-side feedback, adjustable linear regulator references, isolated point-of-load rails, precision comparator thresholds, and ADC/DAC reference circuits. Engineers may also use the TLV431 as a low-cost, low-power replacement for a TL431 where lower minimum cathode current and a smaller SOT-23-5 package are required. When designing with the TLV431, size the cathode bias resistor to keep the device above its minimum operating current (80 µA typical) under worst-case load, and add a capacitor on the reference pin if the application demands transient stability. Because the part ships in the small SOT-23-5 outline, expect to follow standard SMD PCB layout practices - minimize reference-pin leakage and route the cathode trace away from switching nodes. This page synthesizes distributor pricing, drop-in alternatives, and practical design notes not found on the manufacturer datasheet, giving engineers a single reference for sourcing, second-sourcing, and properly biasing the TLV431IDBVR in low-voltage reference designs.
TPD1E01B04DPLR - 0.18 pF ±15 kV ESD Diode | TI
The Texas Instruments TPD1E01B04DPLR is a bidirectional, single-channel TVS ESD protection diode with 0.18 pF typical input capacitance, ±3.6 V working-voltage range, and ±15 kV ESD protection. It is supplied in the compact 2-X2SON DPL surface-mount package, identified by the R ordering suffix, for protection of USB Type-C and Thunderbolt 3 high-speed interfaces. An ESD protection diode is a discrete semiconductor device placed between an exposed connector or signal line and the protected circuitry. It provides a low-impedance transient-current path during electrostatic discharge events, while remaining effectively transparent during normal operation. In the broader hierarchy, the TPD1E01B04 belongs to the TVS diode, ESD suppressor, discrete semiconductor, and circuit-protection categories. The low 0.18 pF capacitance minimizes loading on high-speed data lines. Texas Instruments states that the device can protect interfaces operating up to 20 Gbps when the circuit is implemented with suitable signal-integrity practices. The bidirectional structure supports protection in either signal polarity, while the ±3.6 V working-voltage specification places the device on low-voltage connector pins. The manufacturer lists maximum IEC 61000-4-2 Level 4 ESD dissipation capability and ±15 kV protection. The DPL package occupies only 0.6 mm by 0.3 mm according to the distributor listing, helping designers conserve PCB area in dense USB-C, Thunderbolt, and other high-speed interface layouts. Typical applications include USB Type-C connector ESD protection, Thunderbolt 3 interface protection, high-speed data-line protection, and compact consumer or industrial equipment. The device is most useful when its protection placement is close to the connector and its capacitance is acceptable to the target signal path. The primary design consideration is signal integrity: place the device near the connector entry, use short and properly referenced connections, and verify that the added capacitance does not degrade edge rate or insertion loss. Do not infer ratings or package details not stated in the manufacturer or distributor sources.
TPD1E01B04DPLT - 0.18 pF ±15 kV ESD Diode | Texas Instruments
The Texas Instruments TPD1E01B04DPLT is a bidirectional, single-channel TVS ESD protection diode with 0.18 pF typical I/O capacitance, ±3.6 V working voltage, and ±15 kV ESD capability, packaged in a surface-mount 2-X2SON package measuring 0.6 mm by 0.3 mm. It is designed to protect high-speed interfaces, including USB Type-C and Thunderbolt 3 links operating up to 20 Gbps. A TVS diode is a transient-voltage-suppression device that diverts short ESD pulses away from sensitive circuitry while remaining effectively transparent during normal operation. An ESD protection diode belongs to the surge-protection and discrete-semiconductor hierarchy, where low capacitance and fast response preserve high-speed signal integrity. TPD1E01B04 is a compact protection device intended for connector-side or signal-line protection rather than continuous power regulation. The principal features are its extremely low 0.18 pF typical input capacitance, bidirectional conduction, ±15 kV air ESD rating as identified by the manufacturer and distributor listings, and IEC 61000-4-2 Level 4 system-level ESD capability. The low capacitance helps avoid edge degradation and bandwidth loss on USB Type-C, Thunderbolt, and other high-speed data lines. Its 2-X2SON package supports compact PCB layouts where board area is constrained. The device is specified for a nominal operating voltage of ±3.6 V and is presented in verified distributor data as a 15 V typical clamp device with 2.5 A peak pulse current for an 8/20 microsecond waveform. The verified data also identifies a 2.5 A Ipp rating, 0.2 pF as the alternate catalog value, and an operating temperature range of -40 °C to +125 °C. Exact pin naming and package drawing details should be checked in the manufacturer datasheet before layout release. Typical applications include USB Type-C connector protection, Thunderbolt 3 interface protection, high-speed communication ports, and ESD protection for compact consumer or industrial electronics. Place the diode close to the connector and route protected traces away from unprotected circuitry. Confirm signal-line voltage, capacitance budget, ESD system requirements, and the complete datasheet waveform and pin configuration during design review. The key engineering trade-off is extremely low capacitance versus transient-current handling. TPD1E01B04 prioritizes low loading for data-rate preservation, while a different TVS may provide higher surge-current capability at the cost of added capacitance. This page combines verified manufacturer and distributor data with practical placement and selection guidance.
TPD1E01B04DPYR - 0.18pF ESD Diode USB Type-C | Texas Instruments
The Texas Instruments TPD1E01B04DPYR is a single-channel bidirectional TVS ESD protection diode with 0.18 pF typical IO capacitance, ±3.6 V reverse standoff voltage, and ±15 kV ESD strike tolerance (IEC 61000-4-2 Level 4), housed in a 2-pin X1SON (DPY, 0402/DFN1006 footprint) surface-mount package. An ESD protection diode, also called a TVS (transient voltage suppressor) diode or ESD suppressor, is a semiconductor device that clamps high-voltage electrostatic discharge transients before they reach sensitive ICs. In the system hierarchy it sits at the board level as a passive-class protection component within the broader circuit-protection family, complementing fuses, varistors, and surge protectors. Because it is placed directly on high-speed signal lines, its line-to-line capacitance directly determines how much signal integrity degradation the protected interface suffers. Key differentiating specifications of the TPD1E01B04 are its extremely low 0.18 to 0.20 pF typical IO capacitance, which preserves eye diagrams on interfaces running up to 20 Gbps; its low dynamic resistance (R_DYN), which yields a low clamping voltage during an ESD event; and its bidirectional topology, which allows it to protect lines carrying signals that swing both above and below ground. According to the TI datasheet, the device is rated at the maximum level of the IEC 61000-4-2 international standard (Level 4, ±15 kV air / ±8 kV contact category commonly cited for this class), and DigiKey lists a 15 V clamp voltage with 2.5 A (8/20 us) Ipp. Architecturally, the TPD1E01B04 uses a deep snapback-free bidirectional TVS structure optimized for sub-0.2 pF loading. This is achieved through a small-die design whose junction geometry minimizes parasitic capacitance while maintaining the current handling needed for repeated ESD strikes. Low dynamic on-resistance means that during a discharge the voltage presented to the protected PHY stays low, reducing the stress on downstream transceiver pins. Typical applications include USB Type-C and Thunderbolt 3 port protection, SuperSpeed USB 3.x and USB4 differential pairs, HDMI and DisplayPort high-speed lanes, and other high-speed interfaces up to 20 Gbps where lower-capacitance TVS parts would attenuate or distort the signal. Design consideration: place the DPY package within a few millimeters of the connector pin being protected, with a short, direct low-inductance path to ground; excess trace inductance raises the effective clamping voltage during fast ESD edges.

TPD1E01B04DPYT - 0.18pF ±3.6V ESD Protection Diode | TI
The Texas Instruments TPD1E01B04DPYT is a single-channel bidirectional TVS ESD protection diode with 0.18 pF to 0.20 pF typical input capacitance, a ±3.6 V reverse standoff voltage, and a 15 V clamping voltage at 2.5 A (8/20 us) Ipp, housed in a 2-pin X1SON (DPY, 0402 footprint, 1.0 x 0.6 mm) surface-mount package. A TVS (transient voltage suppressor) diode is a circuit-protection semiconductor that diverts fast, high-energy transient events - such as electrostatic discharge (ESD), cable discharge, and induced surge - away from sensitive ICs. Within the power-protection hierarchy, the TPD1E01B04 belongs to the ESD-protection subfamily of TVS diode arrays, positioned alongside surge suppressors and circuit-protection ICs on the signal path of high-speed digital interfaces. Key features include IEC 61000-4-2 Level 4 ESD immunity (air-gap discharge up to ±15 kV and contact discharge performance at the maximum Level 4 rating), ultra-low 0.18 pF to 0.20 pF line capacitance that preserves signal integrity on data rates up to 20 Gbps, and a bidirectional architecture that requires no polarity orientation on symmetric lines. The DPY 0402 (X1SON/XDFN-2) leadless package minimizes parasitic inductance, which directly reduces clamping voltage during sub-nanosecond ESD events. The device uses a bidirectional TVS diode structure that remains invisible to the signal line in normal operation: at the ±3.6 V standoff it draws negligible leakage, then clamps fast transient overvoltage events to safe levels within nanoseconds. This combination of low capacitance and low clamping voltage is what distinguishes USB-C and Thunderbolt 3 rated parts from general-purpose TVS diodes. Typical applications include USB Type-C SuperSpeed lane protection (USB 3.2 and USB4 up to 20 Gbps), Thunderbolt 3 port protection, HDMI and DisplayPort auxiliary channels, and other high-speed differential pairs in smartphones, tablets, docking stations, and notebooks. Design consideration: place the diode as close to the connector as possible with a solid, short ground return - stub length between the protected line and the diode adds parasitic inductance that degrades clamping performance. Insertion loss should be re-simulated when channel data rates exceed 10 Gbps.

TPD1E04U04DPYR - 0.5pF ESD TVS Diode 3.6V | Texas Instruments
The Texas Instruments TPD1E04U04DPYR is a single-channel unidirectional ESD protection TVS diode with 0.5 pF IO capacitance, a 3.6 V reverse standoff voltage, and IEC 61000-4-2 Level 4 protection of ±16 kV (contact and air), housed in a 2-pin X1SON (0402-class, 1.0 mm x 0.60 mm) surface-mount package. It clamps at 8.9 V and dissipates up to 2.5 A (8/20 µs) of impulse peak current. An ESD protection diode, also called a TVS (transient voltage suppressor) diode, is a semiconductor device within the broader family of circuit protection components that shunts electrostatic discharge events away from sensitive integrated circuits. In the system hierarchy, ESD protection sits between external connectors and internal SoCs, providing a low-impedance path to ground when a transient voltage exceeds the diode trigger threshold, then returning to a high-impedance state. Key features include the ultra-low 0.5 pF channel capacitance, which preserves signal integrity on high-speed interfaces up to 6 Gbps such as HDMI 2.0 and USB 3.0; a low dynamic resistance (RDYN) that yields an ultra-low clamping voltage during strikes; and a compact 2-X1SON footprint that fits directly at the connector. According to the TI datasheet, the device is rated for ESD strikes above the maximum level specified in IEC 61000-4-2 (Level 4). Architecturally, the TPD1E04U04 uses a unidirectional steering-diode topology with a precision internal trigger structure, so it normally presents only 0.5 pF of loading to the protected line. The low RDYN is the critical parameter: during a discharge, clamping voltage equals breakdown voltage plus strike current multiplied by dynamic resistance, so minimizing RDYN directly reduces residual voltage at the protected SoC. Typical applications include HDMI 2.0 port protection, USB 3.0/3.1 connector protection, and other high-speed differential or single-ended lines such as eMMC or MIPI interfaces where capacitance budget is under 1 pF. Operating range is -40C to +125C, suiting automotive-adjacent and industrial designs. Design tip: place the TPD1E04U04 within a few millimeters of the connector, before any series elements, and route the ground path with low-inductance vias to the ground plane; excessive series inductance raises effective clamping voltage.

TPD1E04U04DPYT - 0.5pF 3.6V ESD TVS Diode | TI | USB 3.0
The Texas Instruments TPD1E04U04DPYT is a unidirectional TVS ESD protection diode with 0.5 pF IO capacitance, 3.6 V reverse standoff voltage, ±16 kV IEC 61000-4-2 contact ESD rating, and 8.9 V clamping voltage at 2.5 A (8/20 us) Ipp, housed in a 2-pin X1SON (DPY, 0402 footprint) surface-mount package. An ESD protection diode, also called a TVS (transient voltage suppressor) diode or ESD suppressor, is a type of clamping device in the broader circuit-protection hierarchy (circuit protection -> surge protectors -> TVS diodes). It sits on high-speed signal lines and shunts electrostatic-discharge transients to ground before they reach sensitive silicon, while remaining invisible to the signal in normal operation. Key features include ultra-low 0.5 pF insertion capacitance, which preserves signal integrity on interfaces running up to 6 Gbps such as HDMI 2.0 and USB 3.0; low dynamic resistance (RDYN), which produces an ultra-low clamping voltage during a strike; and compliance with IEC 61000-4-2 Level 4, exceeding the ±16 kV contact-discharge maximum of that international standard. Technically, the unidirectional topology clamps positive transients to a low forward-voltage path and negative transients to the diode breakdown region. The low dynamic resistance between the trigger and clamping regions is the parameter that distinguishes this device from conventional TVS diodes: lower RDYN directly translates to less residual voltage reaching the protected SoC during system-level ESD events. Typical applications are HDMI 2.0 port protection, USB 3.0 SuperSpeed lane protection, and any high-speed differential pair on smartphones, tablets, docking stations, and set-top boxes where sub-1-pF capacitance is mandatory. Design consideration: place the diode as close to the connector as possible so the transient is clamped before it propagates along the trace; short stubs matter more than the diode itself at 6 Gbps.

TPD1E10B06DPYR - Single-Channel ESD TVS Diode, ±30kV | TI
The Texas Instruments TPD1E10B06DPYR is a single-channel ESD protection TVS diode rated for ±30kV contact and ±30kV IEC air-gap ESD discharge in a compact 2-pin X1SON (DPY) package measuring approximately 1.0 x 0.6 mm. It provides a 14V working voltage rating with 5A peak pulse current (8/20 µs waveform) and integrated back-to-back TVS diodes for bipolar or bidirectional signal support, making it suitable for both positive- and negative-going transients on a single line. What is a TVS diode? A TVS (transient voltage suppressor) diode is a clamping semiconductor that diverts ESD and surge energy away from sensitive downstream ICs. Within the protection hierarchy (TVS -> protection diode -> discrete semiconductor -> electronic component), TVS arrays sit closest to external connectors, where they shunt fast transients (ns-scale ESD, µs-scale surge) before they reach ASICs, MCUs, or analog front-ends. The TPD1E10B06 family uses a back-to-back configuration to handle bipolar signals. Key specifications include 12pF (typical, per DigiKey listing; datasheet lists 10pF IO capacitance typical and 12pF line capacitance) line capacitance, 0.37 Ω dynamic resistance (R_DYNAMIC), and ±6V minimum DC breakdown voltage. The 0402-class footprint frees PCB real estate for high-density mobile and wearable designs where every square millimeter matters. The device is rated for ultra-low leakage current, minimizing quiescent loss on protected lines. Architecturally, the TPD1E10B06 uses a silicon TVS structure with back-to-back Zener diodes, achieving system-level IEC 61000-4-2 ESD immunity. Its low capacitance suits data lines like USB VBUS/ID, audio (microphone, headphone, speakerphone), SD card interfaces, keypads, and GPIO. The bidirectional capability removes the need for two unidirectional TVS in many use cases, halving the BOM on differential or AC-coupled lines. Typical applications include protection for audio lines (microphone, earphone, speakerphone), SD card interfaces, keypad buttons, USB port VBUS/ID pins, and general-purpose GPIO. End-equipment targets are portable devices, wearables, set-top boxes, electronic point-of-sale terminals, and appliances. The low 12pF capacitance preserves signal integrity on high-speed interfaces. Design tip: place the TPD1E10B06DPYR as close as possible to the external connector with a short, low-inductance ground return. Use a dedicated TVS ground via directly to the chassis/ground plane to maximize the IEC 61000-4-2 discharge current path and avoid coupling noise into adjacent signal traces. This component is also available in a larger SOD-523 (DPYT) variant on the same datasheet for layouts needing a different footprint.
TPD1E10B06QDPYRQ1 - 12 pF ±5.5 V ±30 kV ESD Diode | TI
The Texas Instruments TPD1E10B06QDPYRQ1 is a bidirectional single-channel ESD protection diode with 12 pF typical capacitance, ±5.5 V rating, and ±30 kV ESD protection in a 0402 package. It is designed for compact, high-speed interfaces where transient protection must be added without materially loading the signal path. The device provides a 14 V typical clamp voltage and 6 A peak pulse current for an 8/20 microsecond waveform. An ESD protection diode, also called a TVS diode, is a discrete semiconductor device placed beside an exposed circuit line to divert electrostatic discharge pulses into a low-impedance path. The TPD1E10B06-Q1 family combines a bidirectional back-to-back TVS structure with a very small package, making it suitable for signal lines that require both polarity tolerance and low parasitic loading. Its 12 pF capacitance is a key selection parameter for high-speed data lines. The principal features are its ±5.5 V bidirectional rating, 12 pF typical input or line capacitance, ±30 kV contact and air-gap ESD capability as stated by TI, and IEC 61000-4-2 Level 4 qualification. The automotive -Q1 designation identifies the product family for automotive applications. The device is also available in an industry-standard SOD-523 package option, while this orderable MPN uses the compact 0402 form factor identified in the verified data. The bidirectional back-to-back clamp arrangement protects either signal polarity without requiring a separate unidirectional steering arrangement. The small capacitance helps preserve edge integrity in compact connector and interface layouts, but the exact signal-rate impact still depends on the complete channel, trace, connector, and receiver impedance. Engineers should verify that the 12 pF device capacitance is acceptable for the target protocol and that the protected line remains within the device working voltage. Typical applications include automotive infotainment interfaces, USB, control lines, sensor connections, communication interfaces, and other external-accessible signal paths. The 0402 footprint is especially useful where board area is constrained. Placement should be close to the connector or board edge, with the protected trace routed away from unprotected circuitry and a low-inductance return path provided to the protection device. A key design consideration is that the TVS diode protects against ESD transients but does not replace correct signal-integrity layout, connector design, chassis grounding, or system-level surge protection. Verify the maximum working voltage, clamp behavior, pulse rating, capacitance, automotive qualification requirements, and package land pattern against the manufacturer datasheet before production release.
TPD1E10B09DPYR - 10pF, ±9V, ±20kV ESD Protection TVS in 0402 | TI
The Texas Instruments TPD1E10B09DPYR is a single-channel electrostatic discharge (ESD) transient voltage suppression (TVS) diode in a tiny X1SON/0402-class package. It offers ±20 kV IEC 61000-4-2 (level 4) contact and air-gap ESD protection with 10 pF typical line capacitance, a 20 V clamp at 4.5 A (8/20 µs) peak pulse, and ultra-low dynamic resistance of 0.37 Ω for fast transient suppression on low-voltage I/O interfaces. A TVS diode is a solid-state protection device that clamps voltage transients by avalanche breakdown, protecting downstream ICs from ESD and surge events. The TPD1E10B09 fits the product hierarchy: TVS diode → ESD suppressor → circuit protection IC → semiconductor. Back-to-back (bidirectional) TVS configurations allow bipolar AC or asymmetric signal support without external steering diodes, which is essential on differential lines such as USB, HDMI, and audio jack interfaces. Key differentiating specifications include ±30 kV air discharge and ±30 kV contact discharge (per the manufacturer datasheet), 10 pF capacitance (suitable for high-speed signal lines), 1 A peak pulse current with 6 A (8/20 µs) surge rating, and 0.5 µA maximum leakage. The back-to-back diode pair enables bidirectional protection on a single line. The 0402-size X1SON package occupies approximately 1.0 × 0.6 mm of board area—approximately one quarter the size of a discrete 0603 TVS pair, enabling protection in space-constrained wearables, smartphones, and sensor pods. Typical applications include protection for USB 2.0 / USB Type-C data lines, HDMI/MHL signal pairs, audio headset jacks, SIM card and SD card interfaces, and industrial push-button or sensor lines where human-discharge events are common. Designers select this device when sub-1.5 pF-equivalent channel-to-ground capacitance is not required, but ultra-low leakage and a sub-1 mm land pattern are mandatory. When laying out this part, place the TVS diode within 3 mm of the connector with the trace from connector pin directly into one TVS terminal and back to the IC pin—keeping parasitic inductance below 1 nH. Use a ground via adjacent to the device's GND pad to provide a low-impedance discharge path; otherwise the clamping performance degrades under 8 kV contact strikes.
TPD1E10B09DPYT - 20V 4.5A ESD TVS Diode | TI
The Texas Instruments TPD1E10B09DPYT is a single-channel ESD protection TVS diode with a 20 V clamp, 4.5 A peak pulse current for an 8/20 microsecond surge, and a compact 0402 2-X1SON package. The device is designed for bidirectional signal protection, including both bipolar and other low-voltage interfaces, while its 10 pF capacitance helps preserve high-speed signal integrity. A TVS diode is a discrete transient-voltage-suppression device that diverts ESD energy away from sensitive circuitry. TVS protection devices sit at connector entry points, interface lines, and exposed external ports, where electrostatic discharge can otherwise damage low-voltage integrated circuits. The TPD1E10B09 family combines low capacitance with IEC 61000-4-2 level 4 contact and air-gap ESD protection, making it appropriate for compact consumer, industrial, and communications equipment. The TPD1E10B09DPYT provides plus-or-minus 9 V ESD protection, a 20 V clamp voltage, 4.5 A peak pulse current, and 10 pF line capacitance. Its back-to-back TVS structure supports bipolar or bidirectional signal operation. The 0402 package is approximately 1.0 mm by 0.5 mm and is intended for space-constrained boards where protection must be added without materially increasing placement area. Use this device near the connector or entry point of the protected signal rather than deep inside the PCB, where the ESD path becomes longer and inductance can reduce clamping performance. Keep the protected trace short, provide a low-impedance return path, and place the device on the same side of the board as the connector when practical. The protection device should be selected together with the signal's voltage tolerance, bandwidth, and connector geometry. Typical uses include USB, headphone, control, sensor, and other compact serial interfaces exposed to user contact. For high-speed lines, verify that the 10 pF capacitance does not create unacceptable signal attenuation or edge-rate degradation. The device is not intended as a surge protector for sustained overvoltage or power transients beyond the specified ESD test conditions. This page combines verified manufacturer and distributor information with practical ESD-layout guidance. Verify the final footprint, polarity, working voltage, clamp behavior, and system-level ESD immunity on the assembled design before production.
TPD2E001DRLR - 2Ch ESD Protection Array SOT-5 | Texas Instruments
The Texas Instruments TPD2E001DRLR is a 2-channel Transient Voltage Suppressor (TVS) based Electrostatic Discharge (ESD) protection diode array rated to handle ESD strikes up to ±15 kV (HBM) and ±8 kV (IEC 61000-4-2 contact) with a typical channel capacitance of 1.5 pF, housed in a 5-pin SOT (DRL) package for space-constrained high-speed data lines. An ESD protection diode array is a circuit-protection component that shunts transient voltage events to ground, protecting sensitive downstream ICs from electrostatic discharge. In the electronics taxonomy, TVS diode arrays sit under discrete semiconductors > diodes > TVS protection devices, where they form the lowest-level shield in a layered PCB protection strategy (typically used alongside common-mode chokes, PTC fuses, and bulk TVS). Because high-speed interfaces carry multi-Gbps signals, the protection device must add minimal parasitic capacitance so the signal eye diagram remains compliant with USB, HDMI, or LVDS masks. Key features include a working range up to 5.5 V, a typical clamping voltage of 16 V, and a dynamic resistance of 1.2 Ω. Two TVS channels are integrated into one 5-pin SOT package, allowing protection of a differential pair (D+, D-) or two single-ended lines from a single component. The low 1.5 pF line capacitance minimizes insertion loss on USB 2.0, LVDS, HDMI, and Ethernet signal paths, and the device is qualified to IEC 61000-4-2 Level 4 for air and contact discharge. Technically, the TPD2E001DRLR uses a steering-diode + Zener-clamp TVS architecture that biases through an optional VCC pin. When VCC is tied to the protected supply rail, the clamping voltage is tightened; when left floating, the device still clamps but with slightly higher residual voltage. The 1.2 Ω dynamic resistance ensures that even at 8 kV contact discharge the protected IC sees a transient below its absolute-maximum rating. Typical applications include USB 2.0 port protection on laptops and tablets, HDMI and DisplayPort link protection, LVDS line protection in LCD panels, Ethernet PHY protection, and general-purpose ESD protection for any 5 V high-speed data interface. The small SOT-5 footprint lets designers place the diode array immediately adjacent to the connector, minimizing trace inductance between the ESD event and the protection clamp. When designing with this part, place the device within 2 mm of the connector body, keep ground-return loops short (less than 5 mm), and add a 1 μF bypass capacitor near VCC if it is biased; otherwise leave VCC floating. This page synthesizes distributor pricing, pin-compatible TI drop-in alternatives (TPD2E001DRLRG4, TPD2E001DRSR, TPD2E001IDRLRQ1, TPD2E2U06DRLR), and layout guidance not compiled in the manufacturer datasheet alone.
TPD2EUSB30 - 2-Ch 0.7pF USB 3.0 ESD Protector | Texas Instruments
The Texas Instruments TPD2EUSB30 is a dual-channel 0.7-pF, 5.5-V TVS-based ESD protection diode array designed for SuperSpeed USB 3.0 (6 Gbps) interfaces. It provides ±8 kV IEC 61000-4-2 contact discharge protection, ±15 kV air-gap discharge protection, and a 5 A (8/20 µs) surge rating in a 3-pin SOT-3 (DRT) footprint. A Transient Voltage Suppressor (TVS) diode array is a passive protection device that clamps transient over-voltages (such as ESD strikes, cable discharge events, and lightning-induced surges) to a safe level, protecting downstream ICs. TVS arrays sit at the boundary of the ESD-sensitive analog/digital subsystem hierarchy: TVS diode -> ESD protector -> interface protection IC -> power management IC -> semiconductor. Their capacitance and leakage directly affect signal integrity on high-speed lines, making ultra-low capacitance (sub-1 pF) critical for USB 3.0, HDMI, and DisplayPort links. The TPD2EUSB30's key features include 0.7 pF typical line capacitance (compatible with 6 Gbps SuperSpeed signaling), 0.05 µA maximum leakage current, and an 8 V working voltage. Each channel integrates a TVS steering diode plus a TVS clamp, allowing a single 3-pin SOT-23 package to protect two data lines (D+/D-) without requiring an external bias supply. The TPD2EUSB30A variant (pin-compatible) adds integrated VBUS protection. Typical applications include USB 3.0 host and device port protection, USB Type-A and Type-B connectors, USB 3.0 hubs, docking stations, smartphones, tablets, and laptops. Designers select this part when signal-integrity preservation at 5 Gbps and beyond is mandatory and board area is constrained. When designing with this device, place the TPD2EUSB30 within 3 mm of the USB connector and route protected traces directly to the protected IC. Avoid routing protected and unprotected traces in parallel to prevent ESD coupling.

TPD4E001DBVR - 4-Channel 1.5pF ESD Protection | TI
The Texas Instruments TPD4E001DBVR is a four-channel transient voltage suppressor (TVS) based ESD protection diode array with 1.5 pF per-channel IO capacitance, a 5.5 V working voltage, and a maximum leakage current of 1 nA, housed in a 6-pin SOT-23 (DBV) surface-mount package. Rated for +/-8 kV IEC 61000-4-2 contact discharge and up to +/-15 kV air discharge, it is engineered for high-speed data interfaces such as USB 2.0. An ESD protection diode array is a type of TVS (transient voltage suppressor) device that clamps electrostatic-discharge transients on data lines before they can damage sensitive downstream ICs. Within the signal-chain protection hierarchy, it sits between the connector and the transceiver, forming a key element of a system-level circuit-protection strategy alongside fuses, varistors, and surge suppressors. Key features include four bidirectional ESD clamp channels in one compact package, ultra-low 1.5 pF channel capacitance that preserves signal integrity on 480 Mbps USB 2.0 lines, 1 nA maximum leakage current for minimal power impact, and a VCC pin that enables flow-through layout and reference clamping. The device meets IEC 61000-4-2 Level 4, the most severe international ESD test level. The TPD4E001 architecture uses TVS diode clamping elements from each IO pin to both VCC and GND rails, steering strike current away from the protected IC while keeping the clamping voltage low. The low junction capacitance is achieved through a proprietary diode structure, allowing the array to be placed directly on the differential pair without significant eye-diagram degradation. Typical applications include USB 2.0 port protection, Ethernet and other high-speed data lines, and general-purpose IO protection in consumer, industrial, and connectivity products where board space is constrained. Design consideration: place the TPD4E001 as close to the connector as possible so the strike current is clamped before it propagates onto the PCB traces; the VCC pin should be tied to the protected rail with local decoupling. This page synthesizes distributor listings, drop-in alternatives, pinout data, and practical design notes not consolidated in the manufacturer datasheet.
TPD4E001DCKR - 4-Ch 1.5pF 5.5V ESD Protection | TI
The Texas Instruments TPD4E001DCKR is a four-channel, low-capacitance ESD protection diode array with 1.5 pF IO capacitance per channel, 5.5 V operating voltage, and ±8 kV IEC 61000-4-2 contact-discharge protection, housed in a 6-pin SC-70 (DCK/SOT-363) package. An ESD protection array is a type of TVS (transient voltage suppressor) device within the broader circuit-protection hierarchy. Its role is to divert electrostatic-discharge transients away from sensitive high-speed data lines before they reach downstream ICs such as USB transceivers, Ethernet PHYs, or microcontrollers. Low line capacitance is the defining parameter, because excessive capacitance distorts fast edge-rate signals like USB 2.0 (480 Mbps). Key features include ultra-low 1.5 pF per-channel capacitance that preserves signal integrity on USB 2.0 and other high-speed interfaces, a maximum leakage current of only 1 nA to minimize battery drain in portable systems, a 5.5 V reverse working voltage suitable for 5 V and USB VBUS-adjacent rails, and ESD robustness at IEC 61000-4-2 Level 4 (±8 kV contact). The four-channel array format protects a full differential pair plus auxiliary lines in a single tiny package. Architecturally, the TPD4E001 uses TVS-based steering and clamping diodes. On negative-going transients the clamp conducts within nanoseconds, clamping residual voltage at the protected IC far below the absolute-maximum levels of typical transceiver silicon. The device also provides a VCC pin that allows transients to be diverted into the supply rail with lower clamping on protected lines. Typical applications are USB 2.0 ports, HDMI/DVI auxiliary and control lines, Ethernet MDI auxiliaries, keypads, and general-purpose high-speed GPIO on consumer, connectivity, and industrial boards. When designing, route the TPD4E001DCKR as the first component after the connector with a short, low-inductance ground return; excessive trace inductance degrades clamping performance during an 8 kV strike.
