Product details
Overview
P4KE100C from Taiwan Semiconductor is a unidirectional 400W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 100 V, clamps transients to ≤144 V at 2.9 A peak pulse current, and maintains low leakage (<1 μA at 81 V), making it suitable for automotive body electronics, industrial PLC I/O protection, and AC/DC adapter input stages.
For engineers reviewing the P4KE100C datasheet, P4KE100C pinout, P4KE100C application, or P4KE100C equivalent, key selection criteria include its DO-41 package compatibility, 100 V working stand-off voltage, 144 V clamping performance under 10/1000 μs surge, and AEC-Q101 qualification status for automotive-grade reliability.
Technical Context
The P4KE100C operates as a unidirectional avalanche diode with a tightly specified breakdown range of 90–110 V at 1 mA test current. Its clamping action begins within <1.0 ps from 0 V to VBR, enabling effective suppression of fast ESD and EFT events per IEC 61000-4-2 and -4-4 standards.
It delivers 400 W peak pulse power at TA = 25°C using the standardized 10/1000 μs waveform, with thermal derating to zero at 175°C junction temperature. The device exhibits a positive temperature coefficient of VBR (+0.106 %/°C), ensuring stable clamping behavior across its –55°C to +175°C operating range.

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 | Surface-mount SMB package; 100 V standoff; 156 V clamping at 2.6 A; 600 W peak power | Better suited for space-constrained PCBs; higher clamping voltage reduces margin for 12 V logic interfaces | Select when board area is limited and 156 V clamping is acceptable for downstream 15 V-rated components |
| 1N6277A | Same DO-41 package; 100 V standoff; 144 V clamping at 2.9 A; identical electrical specs but non-AEC-Q101 rated | Lacks automotive qualification; suitable for industrial/commercial use where AEC-Q101 is not mandated | Choose for cost-sensitive non-automotive designs requiring identical form, fit, and function without qualification overhead |
Compared with SMBJ100A and 1N6277A, the P4KE100C uniquely combines DO-41 through-hole compatibility, AEC-Q101 qualification, and precise 144 V clamping-making it optimal for automotive and industrial applications demanding proven reliability and legacy assembly support.

FAQ
What is the clamping voltage of P4KE100C under standard 10/1000 μs surge conditions?
The P4KE100C clamps to a maximum of 144 V when subjected to its rated 2.9 A peak pulse current under the 10/1000 μs waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream component voltage margining in designs using the P4KE100C.
Is P4KE100C suitable for bidirectional transient protection?
No, P4KE100C is a unidirectional TVS diode intended for DC line protection with defined anode/cathode polarity. For bidirectional protection, the P4KE100CA variant must be used-its symmetrical breakdown and clamping characteristics support AC or floating signal line applications where polarity reversal occurs.
Does P4KE100C meet automotive qualification standards?
Yes, P4KE100C is AEC-Q101 qualified, having passed stress tests for temperature cycling, humidity bias, mechanical shock, and high-temperature operating life. This certification confirms its suitability for automotive powertrain, chassis, and body electronics applications per the P4KE series N2104 specification.
What is the maximum steady-state power dissipation for P4KE100C at 75°C lead temperature?
The P4KE100C has a steady-state power dissipation rating of 1 W when mounted on 5 × 5 mm copper pads per lead at a lead temperature of 75°C. This derated value reflects thermal limits under continuous DC stress and is distinct from its 400 W non-repetitive surge capability.
How does the temperature coefficient affect P4KE100C's breakdown voltage stability?
P4KE100C has a VBR temperature coefficient of +0.106 %/°C, meaning its breakdown voltage increases by approximately 0.106% per degree Celsius rise in junction temperature. This positive drift improves clamping margin at elevated temperatures, supporting reliable operation in under-hood environments up to 175°C.
