Product details
Overview
P4KE100A-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 100 V breakdown voltage (VBR min/max = 95.0–105 V), 85.5 V stand-off voltage (VWM), 137 V 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 P4KE100A-E3/54 datasheet, P4KE100A-E3/54 pinout, P4KE100A-E3/54 application, or P4KE100A-E3/54 equivalent, key selection criteria include clamping performance under 2.9 A transient current, unidirectional polarity with cathode band marking, DO-41 mechanical compatibility, AEC-Q101 qualification status, and thermal resistance (RθJL = 66 °C/W) for board-level surge protection design.
Technical Context
This TVS diode operates as a voltage-clamped shunt protector: when reverse voltage exceeds VWM (85.5 V), it avalanches near VBR (95.0–105 V) and clamps transients to ≤137 V at rated IPPM. Its glass-passivated junction ensures stable breakdown and low leakage (<1.0 μA at VWM), while the DO-41 package supports manual or wave soldering per JESD 22-B106 (275 °C, 10 s).
It is rated for non-repetitive 10/1000 μs pulses up to 400 W, with derating above 25 °C ambient per Fig. 2, and handles 40 A forward surge (8.3 ms half-sine) - critical for automotive and industrial power rail protection where IFSM and thermal impedance (RθJA = 100 °C/W) directly impact reliability under repeated surge events.
Key Specifications

| VBR (min/max) | 95.0 V / 105 V - defines precise avalanche onset range for reliable overvoltage triggering |
| VWM | 85.5 V - maximum continuous reverse operating voltage before leakage rises significantly |
| VC @ IPPM | 137 V at 2.9 A - clamping voltage limiting downstream circuit stress during 10/1000 μs surge |

| IPPM | 2.9 A - maximum non-repetitive peak pulse current supported at rated clamping voltage |
| RθJL | 66 °C/W - junction-to-lead thermal resistance enabling effective heat transfer to PCB copper |
| TJ max | +175 °C - maximum junction temperature supporting operation in under-hood automotive environments |

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; lower RθJA (50 °C/W); same VBR (95–105 V), but higher IPPM (3.2 A) and lower VC (156 V) | Better thermal performance in high-density layouts; suited for automated SMT assembly vs. through-hole P4KE100A-E3/54 | Select SMBJ100A when board space and reflow compatibility are prioritized over legacy through-hole serviceability. |
| 1.5KE100A | Same DO-41 package; higher PPPM (1500 W); identical VBR/VWM, but higher VC (165 V) and IPPM (9.1 A) | Designed for higher-energy transients (e.g., Level 4 IEC 61000-4-5); larger footprint and higher cost than P4KE100A-E3/54 | Choose 1.5KE100A only when system-level testing requires >400 W surge margin; otherwise P4KE100A-E3/54 offers optimal cost/performance balance. |
Compared with SMBJ100A and 1.5KE100A, P4KE100A-E3/54 delivers standardized 400 W protection in a proven through-hole DO-41 format with AEC-Q101 qualification, making it ideal for cost-sensitive, serviceable, and automotive-qualified designs where moderate surge energy suffices.

FAQ
What is the polarity configuration of the P4KE100A-E3/54?
The P4KE100A-E3/54 is a unidirectional transient voltage suppressor diode. Its cathode is marked by a color band on the DO-41 package body, and it conducts in forward bias while clamping reverse transients above its breakdown voltage. This configuration makes P4KE100A-E3/54 suitable for DC rail protection where polarity is fixed, unlike bidirectional variants that omit the band and protect both voltage polarities.
Does the P4KE100A-E3/54 meet automotive reliability standards?
Yes, the P4KE100A-E3/54 is AEC-Q101 qualified, confirming its suitability for automotive applications including engine control units, body electronics, and infotainment systems. The E3 suffix denotes RoHS-compliant commercial grade with JESD 201 class 1A whisker resistance, and its 175 °C maximum junction temperature supports under-hood deployment. P4KE100A-E3/54 has passed stress tests for temperature cycling, humidity, and mechanical shock per AEC-Q101 requirements.
What is the clamping behavior of the P4KE100A-E3/54 under a standard 10/1000 μs surge?
Under a 10/1000 μs waveform, the P4KE100A-E3/54 clamps at 137 V when subjected to its rated peak pulse current of 2.9 A. This clamping voltage is guaranteed across manufacturing lots and temperature ranges, ensuring consistent protection margin for downstream components. The low incremental surge resistance of P4KE100A-E3/54 minimizes voltage overshoot during fast-rising transients, enhancing reliability in real-world surge events.
How does the DO-41 package of the P4KE100A-E3/54 affect thermal performance?
The DO-41 (DO-204AL) package of the P4KE100A-E3/54 provides a junction-to-lead thermal resistance (RθJL) of 66 °C/W and junction-to-ambient (RθJA) of 100 °C/W with 10 mm lead length. This enables effective heat dissipation into PCB copper pours or chassis connections, especially important during repetitive surge events. Unlike surface-mount alternatives, the axial DO-41 leads of P4KE100A-E3/54 allow direct thermal coupling to internal ground planes via through-hole vias, improving sustained power handling.
Can the P4KE100A-E3/54 be used in bidirectional protection circuits?
No, the P4KE100A-E3/54 is strictly unidirectional and must not be substituted for bidirectional protection without circuit redesign. Bidirectional variants (e.g., P4KE100CA) use symmetric construction and lack polarity markings, whereas P4KE100A-E3/54 has a defined cathode band and only clamps in reverse bias. Using P4KE100A-E3/54 in AC or floating applications risks forward conduction and failure; always verify polarity alignment before integrating P4KE100A-E3/54 into the design.
