Product details
Overview
P4KE100AHE3/54 from Vishay General Semiconductor is a unidirectional TransZORB® transient voltage suppressor diode in DO-41 package, rated for 100 V breakdown voltage (95–105 V), 400 W peak pulse power (10/1000 μs), and 137 V maximum clamping voltage at 2.9 A peak pulse current. It provides robust ESD and surge protection for DC power rails and signal lines in automotive and industrial control systems.
For engineers reviewing the P4KE100AHE3/54 datasheet, P4KE100AHE3/54 pinout, P4KE100AHE3/54 application, or P4KE100AHE3/54 equivalent, this page delivers verified electrical parameters, AEC-Q101 qualification status, thermal resistance (RθJL = 66 °C/W), DO-41 mechanical dimensions, and real-world protection use cases - all confirmed from Vishay's official document #88365 (Rev. 16-Sep-2021).
Technical Context
The P4KE100AHE3/54 operates as a unidirectional avalanche diode with glass-passivated junction, optimized for fast response (<1 ns) to transient overvoltages. Its 100 V nominal breakdown voltage is tested at 1.0 mA, with stand-off voltage of 85.5 V and leakage current ≤1.0 μA at that level.
Thermally, it supports operation from –55 °C to +175 °C junction temperature, with 1.5 W steady-state power dissipation on infinite heatsink at 75 °C lead temperature. The device meets AEC-Q101 stress testing requirements and is RoHS-compliant with matte tin-plated leads.

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 (SMB), lower RθJA (50 °C/W), same VBR range but 600 W PPPM | Better thermal performance in surface-mount layouts; higher surge margin for space-constrained designs | Select SMBJ100A when board space is limited and PCB copper area allows efficient heat spreading |
| 1.5KE100A | Same DO-41 package, identical VBR/VC, but 1500 W PPPM and higher IPPM (12.3 A) | Higher energy handling for severe surge environments (e.g., outdoor telecom cabinets) | Choose 1.5KE100A where IEC 61000-4-5 Level 4 or ISO 7637-2 Pulse 5a stress levels apply |
Compared with SMBJ100A and 1.5KE100A, the P4KE100AHE3/54 offers AEC-Q101 qualification and optimized cost-performance balance for automotive and industrial applications requiring proven reliability in axial-leaded through-hole assembly.

FAQ
What is the breakdown voltage tolerance for P4KE100AHE3/54?
The P4KE100AHE3/54 has a specified breakdown voltage range of 95.0 V to 105 V at 1.0 mA test current, corresponding to ±5 % tolerance around the nominal 100 V rating. This tight VBR window ensures predictable clamping behavior in precision protection circuits and aligns with Vishay's published data sheet #88365 (Rev. 16-Sep-2021).
Is P4KE100AHE3/54 suitable for automotive applications?
Yes, the P4KE100AHE3/54 is AEC-Q101 qualified and explicitly rated for automotive use. Its construction includes glass-passivated junction, matte tin-plated leads compliant with J-STD-002, and operation up to +175 °C junction temperature - all validated per AEC stress test requirements. The HE3 suffix denotes this qualification.
What is the maximum clamping voltage of P4KE100AHE3/54 under surge conditions?
The P4KE100AHE3/54 exhibits a maximum clamping voltage (VC) of 137 V at its rated peak pulse current (IPPM) of 2.9 A, measured using the standard 10/1000 μs waveform. This value is guaranteed per Vishay's datasheet #88365 and defines the upper voltage limit imposed on protected circuitry during transient events.
Does P4KE100AHE3/54 have bidirectional capability?
No, P4KE100AHE3/54 is a unidirectional transient voltage suppressor. Its part number ends in "A", indicating unidirectional polarity with cathode marked by a band. Bidirectional variants use the "CA" suffix (e.g., P4KE100CA); the P4KE100AHE3/54 conducts only when anode-to-cathode voltage exceeds VBR.
What packaging format is used for P4KE100AHE3/54?
P4KE100AHE3/54 is supplied in 13-inch diameter paper tape and reel packaging, with a base quantity of 5500 units per reel (package code "54"). This format supports automated pick-and-place insertion and is consistent with Vishay's ordering information in document #88365.
