Product details
Overview
P4KE100 from Taiwan Semiconductor is a unidirectional 400W transient voltage suppressor (TVS) diode designed for primary 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 operates within -55°C to +175°C junction temperature range-ideal for automotive power supply input protection.
For engineers reviewing the P4KE100 datasheet, P4KE100 pinout, P4KE100 application, or P4KE100 equivalent, key selection criteria include its DO-41 package compatibility, 81.0 V working stand-off voltage, <1 μA reverse leakage at rated VWM, and fast sub-nanosecond response to ESD and lightning-induced surges.
Technical Context
The P4KE100 employs an avalanche breakdown mechanism to divert high-energy transients away from sensitive downstream circuitry. Its unidirectional configuration provides forward conduction capability with 3.5 V VF at 25 A, enabling use in both clamp and crowbar-like protection schemes.
Rated for 400 W peak pulse power under 10/1000 μs waveform per IEC 61000-4-5, it sustains up to 40 A non-repetitive forward surge current and exhibits a low 0.106 %/°C VBR temperature coefficient-critical for stable clamping across wide ambient ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 100 V - defines the approximate DC operating rail where clamping initiates |
| Breakdown Voltage VBR | 90–110 V @ 1 mA - ensures reliable turn-on before system damage threshold |
| Working Stand-off Voltage VWM | 81.0 V - maximum continuous DC voltage the device blocks without leakage |
| Clamping Voltage VC | 144 V @ 2.9 A - peak voltage seen by protected circuit during worst-case surge |
| Peak Pulse Power PPK | 400 W - energy-handling capacity for 10/1000 μs transients per IEEE C62.35 |
| Junction Temperature Range | -55°C to +175°C - supports under-hood automotive and industrial environments |
| Reverse Leakage ID | <1 μA @ 81.0 V - minimal standby power loss and no false triggering |
Pinout & Package

| Fast transient response | <1.0 ps rise time from 0 V to VBR - protects against nanosecond-scale ESD events |
| Low clamping ratio | VC/VBR = 144/90 ≈ 1.6 - minimizes overvoltage stress on downstream ICs |
| High reliability construction | AEC-Q101 qualified option available (P4KE100H); JESD201 Class 2 whisker resistance - suitable for automotive production |

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse P4KE100A | Tighter VBR tolerance (95–105 V vs. 90–110 V); lower clamping voltage (137 V vs. 144 V) | Better suited for systems requiring tighter voltage margin below 150 V absolute max rating | Select P4KE100A when clamping headroom is constrained and tighter VBR distribution improves yield |
| ON Semiconductor 1N6277A | Same DO-41 package; identical 100 V nominal rating but higher 150 V clamping voltage at 2.7 A | Lower surge current rating (2.7 A vs. 2.9 A) and reduced thermal margin in sustained surge conditions | Choose only if legacy design reuse mandates ON Semi footprint; verify clamping margin with actual surge profile |
Compared with P4KE100, the P4KE100A offers tighter parametric control and lower clamping for precision-sensitive rails, while the 1N6277A trades clamping performance for broader second-source availability-neither is pin-compatible without layout verification due to differing thermal derating curves.

FAQ
What is the maximum clamping voltage of the P4KE100 under standard test conditions?
The P4KE100 clamps to a maximum of 144 V when subjected to a 10/1000 μs surge waveform at 2.9 A peak pulse current, as specified in the Taiwan Semiconductor datasheet revision N2104. This value represents the upper limit of voltage imposed on protected circuitry during worst-case transient events and is measured at TA = 25°C with defined test fixture conditions.
Is the P4KE100 suitable for bidirectional transient protection?
No, the P4KE100 is a unidirectional TVS diode intended for DC line protection with polarity-sensitive placement. For bidirectional applications, the P4KE100CA variant must be used-its symmetrical breakdown characteristic allows clamping in both polarities, whereas the P4KE100 conducts only in reverse bias and forward-conducts like a standard diode.
What is the working stand-off voltage (VWM) of the P4KE100, and why does it matter?
The P4KE100 has a working stand-off voltage (VWM) of 81.0 V, meaning it remains in high-impedance blocking mode for all continuous DC voltages up to this level. This parameter ensures no significant leakage current flows during normal operation, avoiding power loss or false triggering-critical for battery-powered or low-quiescent-current systems using the P4KE100.
Does the P4KE100 meet automotive qualification standards?
The base P4KE100 is not AEC-Q101 qualified; however, the P4KE100H variant-identical in electrical specs but manufactured under automotive-grade process controls-is fully AEC-Q101 qualified. Engineers specifying P4KE100 for automotive use must select the H-suffix version and verify compliance documentation directly from Taiwan Semiconductor's qualified parts list.
How does the P4KE100 compare to the P4KE100A in terms of breakdown voltage tolerance?
The P4KE100 specifies a breakdown voltage (VBR) range of 90–110 V at 1 mA test current, while the P4KE100A narrows this to 95–105 V. This ±5% tolerance improves design margin predictability in systems where clamping onset must occur tightly around 100 V, making the P4KE100A preferable for applications demanding tighter statistical distribution of VBR across production lots.
