Product details
Overview
P4KE100HE3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed for circuit-level ESD and surge protection. It features a 85.5 V stand-off voltage (VWM), 95–105 V breakdown voltage (VBR) at 1 mA, 137 V maximum clamping voltage at 2.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform - deployed on power rails and signal lines of automotive sensor modules.
For engineers reviewing the P4KE100HE3/54 datasheet, P4KE100HE3/54 pinout, P4KE100HE3/54 application, or P4KE100HE3/54 equivalent, key selection criteria include clamping voltage margin vs. protected IC's absolute maximum rating, junction temperature derating above 25 °C, AEC-Q101 qualification status, and DO-41 lead-form compatibility with legacy through-hole layouts.
Technical Context
This device operates as a unidirectional avalanche diode, triggering when reverse voltage exceeds its specified VBR range (95–105 V). Its glass-passivated junction ensures stable breakdown characteristics and low leakage (<1 μA at 85.5 V), while thermal resistance (RθJL = 66 °C/W) supports transient energy dissipation without thermal runaway under repetitive surges.
The P4KE100HE3/54 complies with AEC-Q101 stress testing for automotive use and meets JESD 201 Class 2 whisker resistance. Its 10/1000 μs waveform response enables suppression of inductive switching transients and lightning-induced surges in 12 V and 24 V vehicle subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM | 85.5 V - maximum continuous reverse operating voltage before conduction begins; sets safe margin below protected IC's max input rating |
| VBR min/max | 95 V / 105 V at 1 mA - defines precise avalanche onset window for predictable clamping behavior |
| VC @ IPPM | 137 V at 2.9 A - clamping voltage during 10/1000 μs surge; determines worst-case overvoltage seen by downstream circuitry |
| PPPM | 400 W - peak pulse power handling capability; defines survivability against standardized surge events |
| ID @ VWM | <1 μA - ultra-low reverse leakage ensures minimal standby power loss and signal integrity in high-impedance nodes |
| TJ max | +175 °C - extended junction temperature rating enables deployment in under-hood automotive environments |
| AEC-Q101 | Qualified - validated for automotive-grade reliability including temperature cycling, HTRB, and mechanical shock per AEC standard |
Pinout & Package
DO-41 (DO-204AL) molded epoxy package with axial leads; cathode indicated by color band on body; matte tin-plated leads compliant with J-STD-002 solderability and JESD 22-B102 wetting balance.

|---|---|
|
Use Scenario: Protecting analog outputs of pressure, temperature, and position sensors in engine control units exposed to load dump and alternator ripple. IC Role / Device Role / Timing Role: Unidirectional TVS placed between sensor VOUT and ground to clamp negative-going transients and limit positive excursions to 137 V. Use Value: Prevents latch-up or gate oxide damage in downstream op-amps and ADC inputs while maintaining <1 μA leakage at 85.5 V nominal rail. |
Use Scenario: Safeguarding 24 V DC input stages of PLC I/O modules subjected to field-wiring induced surges and relay contact bounce. IC Role / Device Role / Timing Role: Primary overvoltage clamp on main supply rail upstream of DC-DC converter, triggered within <1 ns of transient onset. Use Value: Limits rail collapse to ≤137 V during 400 W surges, preserving regulator functionality and avoiding brownout resets in real-time control loops. |
| Consumer Power Adapter Input | Telecom Line Interface |
|
Use Scenario: Secondary-side surge protection in AC/DC adapters for smart home hubs, guarding against capacitor discharge and hot-plug transients. IC Role / Device Role / Timing Role: Standoff-rated TVS across +12 V output and GND, activated only during overvoltage events exceeding 95 V. Use Value: Enables compliance with UL 62368-1 transient immunity requirements without adding bulk capacitance or active regulation overhead. |
Use Scenario: Front-end protection for RS-485 transceivers in base station backhaul links exposed to induced lightning surges on long cable runs. IC Role / Device Role / Timing Role: Unidirectional clamp on VCC rail feeding transceiver IC, coordinated with series impedance to meet ITU-T K.20 immunity levels. Use Value: Maintains signal integrity by limiting rail perturbation to <137 V during 10/1000 μs surges, preventing transceiver shutdown or data corruption. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ100A | DO-214AA package; 100 V VBR; 300 W PPPM; lower clamping (162 V @ 2.5 A) | Surface-mount layout; higher board density but reduced surge margin vs. P4KE100HE3/54 | Select SMBJ100A when space-constrained PCBs require SMT assembly and 300 W rating suffices |
| 1.5KE100A | DO-201AD package; same VBR range; 1500 W PPPM; larger footprint and higher thermal mass | Higher-energy surge environments (e.g., industrial motor drives); requires larger pad clearance | Choose 1.5KE100A where IEC 61000-4-5 Level 4 (2 kV/2 Ω) immunity is mandated |
Compared with SMBJ100A and 1.5KE100A, the P4KE100HE3/54 delivers optimal balance of AEC-Q101 qualification, through-hole manufacturability, and 400 W surge handling in compact DO-41 - making it preferred for cost-sensitive automotive and industrial through-hole designs requiring validated reliability.

FAQ
What is the clamping voltage of the P4KE100HE3/54 under a 10/1000 μs surge?
The P4KE100HE3/54 exhibits a maximum clamping voltage (VC) of 137 V at 2.9 A peak pulse current under the standardized 10/1000 μs waveform. This value is measured per Figure 1 in Vishay document 88365 and defines the upper voltage limit imposed on protected circuitry during transient events. The P4KE100HE3/54 maintains this clamping performance across its qualified operating temperature range.
Is the P4KE100HE3/54 suitable for automotive applications?
Yes, the P4KE100HE3/54 is AEC-Q101 qualified and explicitly rated for automotive use, including under-hood environments. Its +175 °C maximum junction temperature, glass-passivated junction, and JESD 201 Class 2 whisker resistance meet stringent automotive reliability requirements. The P4KE100HE3/54 is commonly deployed in engine control, body electronics, and ADAS sensor protection circuits.
How does the HE3 suffix differ from the E3 suffix in P4KE100HE3/54?
The HE3 suffix denotes AEC-Q101 qualification and JESD 201 Class 2 whisker resistance, whereas E3 indicates RoHS-compliant commercial grade with JESD 201 Class 1A. Both share identical electrical specs and DO-41 packaging, but only P4KE100HE3/54 is approved for automotive production. The P4KE100HE3/54 undergoes additional stress testing including temperature cycling and HTRB per AEC-Q101.
What is the reverse leakage current of the P4KE100HE3/54 at its stand-off voltage?
At its 85.5 V stand-off voltage (VWM), the P4KE100HE3/54 guarantees a maximum reverse leakage current (ID) of 1.0 μA at 25 °C. This ultra-low leakage preserves signal integrity in high-impedance sensor paths and minimizes standby power loss in battery-powered systems. The P4KE100HE3/54 maintains leakage below 5 μA up to +125 °C per derating curves in the datasheet.
Can the P4KE100HE3/54 be used in bidirectional configurations?
No - the P4KE100HE3/54 is a unidirectional TVS diode, identified by its cathode band marking. Bidirectional operation requires a CA-suffixed variant such as P4KE100CA. Using the P4KE100HE3/54 in reverse-biased AC applications would result in forward conduction and failure. Always verify polarity alignment: cathode connects to the line being protected, anode to reference potential.
