Product details
Overview
P4KE100-E3/54 from Vishay General Semiconductor is a unidirectional Transient Voltage Suppressor (TVS) diode in DO-41 package, designed to protect sensitive electronics against voltage transients induced by inductive load switching and lightning surges. It features a 85.5 V stand-off voltage (VWM), 95–105 V breakdown voltage (VBR at 1 mA), 137 V maximum clamping voltage (VC) at 2.9 A peak pulse current, and 400 W peak pulse power rating with 10/1000 μs waveform.
For engineers reviewing the P4KE100-E3/54 datasheet, P4KE100-E3/54 pinout, P4KE100-E3/54 application, or P4KE100-E3/54 equivalent, key selection considerations include its unidirectional polarity, glass-passivated junction, AEC-Q101 qualification (E3 suffix denotes RoHS-compliant commercial grade), and suitability for automotive sensor line protection, industrial I/O interface surge suppression, and DC power rail transient clamping.
Technical Context
The P4KE100-E3/54 operates as a silicon avalanche diode that enters controlled breakdown above its VWM of 85.5 V, limiting transient voltages to ≤137 V at 2.9 A IPPM. Its 10/1000 μs pulse response enables effective suppression of fast-rising ESD and inductive kickback events without thermal runaway.
It exhibits low incremental surge resistance and very fast response time (<1 ns), with thermal resistance RθJL = 66 °C/W and operating junction temperature range from –55 °C to +175 °C. The device is rated for 40 A non-repetitive forward surge current (8.3 ms half-sine) and has a maximum reverse leakage of 1.0 μA at VWM.
Key Specifications

|---|---|
| VWM | 85.5 V - Maximum continuous reverse working voltage before clamping begins |
| VBR (min/max) | 95.0 / 105 V at 1 mA - Ensures reliable triggering across manufacturing tolerance |
| VC @ IPPM | 137 V at 2.9 A - Clamped voltage seen by protected circuit during 10/1000 μs surge |
| PPPM | 400 W - Peak transient energy absorption capability per single pulse |

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 (smaller footprint), same VWM (85.5 V), slightly higher VC (143 V @ 2.8 A), 600 W PPPM | Better suited for space-constrained PCB layouts; higher power rating allows longer surge duration handling | Select SMBJ100A when board area is limited or higher single-pulse energy margin is required; not drop-in due to different package and thermal profile. |
| 1.5KE100A | Same DO-41 package, identical VWM/VBR/VC, but rated for 1500 W PPPM (10/1000 μs) and higher IPPM (12.3 A) | Designed for higher-energy surge environments (e.g., mains-connected equipment); larger junction area increases thermal mass | Choose 1.5KE100A where legacy DO-41 compatibility is mandatory and surge threat level exceeds 400 W; requires verification of layout thermal relief. |
Compared with SMBJ100A and 1.5KE100A, the P4KE100-E3/54 offers optimal balance of proven automotive qualification, compact DO-41 fit, and sufficient 400 W clamping for mid-tier industrial and automotive subsystems-making it ideal for cost-sensitive, volume production where AEC-Q101 compliance and standardized through-hole assembly are priorities.

FAQ
What is the polarity configuration of the P4KE100-E3/54?
The P4KE100-E3/54 is a unidirectional TVS diode, meaning it functions as a reverse-biased avalanche clamp. Its cathode is marked by a color band on the DO-41 body. In normal operation, it blocks current up to 85.5 V in reverse bias and conducts only during overvoltage events on the cathode side. This configuration is distinct from bidirectional variants (e.g., P4KE100CA) which protect AC or floating signals.
Does the P4KE100-E3/54 meet automotive qualification standards?
Yes, the P4KE100-E3/54 is RoHS-compliant and manufactured to AEC-Q101 qualification requirements for discrete semiconductors. The "E3" suffix confirms compliance with JESD 201 Class 1A whisker testing and full stress-test validation-including temperature cycling, humidity, and mechanical shock-making it suitable for under-hood and chassis-mounted automotive applications.
What is the maximum clamping voltage of the P4KE100-E3/54 during a surge event?
The P4KE100-E3/54 has a maximum clamping voltage (VC) of 137 V when subjected to its rated peak pulse current of 2.9 A using the standard 10/1000 μs waveform. This value represents the highest voltage imposed on the protected circuit during transient suppression and is guaranteed across the full operating temperature range per Vishay specification 88365.
Can the P4KE100-E3/54 be used in bidirectional signal lines?
No-the P4KE100-E3/54 is strictly unidirectional and must not be used on AC-coupled or floating bidirectional signal paths. For such applications, the bidirectional variant P4KE100CA (with CA suffix) is specified, offering symmetrical clamping in both directions. Using the unidirectional P4KE100-E3/54 on bidirectional lines risks forward conduction damage or ineffective protection.
What is the thermal resistance and how does it affect PCB layout for the P4KE100-E3/54?
The P4KE100-E3/54 has a typical junction-to-lead thermal resistance (RθJL) of 66 °C/W. This means that for every watt of sustained power dissipation, the junction temperature rises 66 °C above the lead temperature. Since its steady-state power dissipation (PD) is only 1.5 W, proper PCB copper pour under the leads and adequate airflow are sufficient-no external heatsink is needed for typical transient-only operation.
