Product details
Overview
P4KE100CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for high-energy surge protection in DC power rails and signal lines. It features a 100V nominal standoff voltage, 144V maximum clamping voltage at 2.9A peak pulse current, 400W peak pulse power rating at 10/1000μs waveform, and DO-204AL (DO-41) axial package - deployed in automotive lighting control modules, industrial PLC I/O protection, and PoE-powered device interfaces.
For engineers reviewing the P4KE100CA datasheet, P4KE100CA pinout, P4KE100CA application, or P4KE100CA equivalent, key selection criteria include bidirectional clamping symmetry, low leakage (<1μA @ 81V), fast response (<5ns), AEC-Q101 qualification, and compatibility with 10/1000μs surge immunity standards per IEC 61000-4-5.
Technical Context
The P4KE100CA operates as a bidirectional avalanche diode, providing symmetrical clamping in both polarities without polarity dependence. Its breakdown voltage is specified at 90–110V (min/max) under 1mA test current, with a temperature coefficient of 0.106%/°C - enabling stable overvoltage protection across -55°C to +175°C junction temperatures.
It delivers 400W non-repetitive peak pulse power per ANSI/IEEE C62.35, with clamping voltage tightly bounded at ≤144V at 2.9A (10/1000μs), and exhibits <1μA reverse leakage above its 81V working stand-off voltage - critical for low-power system integrity during normal operation.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Littelfuse SMAJ100CA | Same DO-214AC (SMA) package; 144V VC @ 2.9A; 400W rating; slightly higher IR (5μA @ 81V) | SMA package offers surface-mount compatibility but requires PCB rework vs. through-hole DO-41 | Select when automated SMT assembly is prioritized over legacy through-hole compatibility |
| ON Semiconductor 1.5KE100CA | Higher PPK (1500W); same VWM (81V), VC (144V); DO-201AE (DO-27) package; longer lead time | Supports higher-energy surges (IEC 61000-4-5 Level 5) but larger footprint and thermal mass | Select when system-level surge testing exceeds 4kV or requires margin beyond 400W |
Compared with SMAJ100CA and 1.5KE100CA, the P4KE100CA provides identical clamping performance in a cost-optimized, AEC-Q101-qualified axial package - making it ideal for high-volume automotive and industrial designs where DO-41 mounting and qualification are mandatory.

FAQ
What is the clamping voltage of the P4KE100CA under standard 10/1000μs surge conditions?
The P4KE100CA has a maximum clamping voltage (VC) of 144 V at 2.9 A peak pulse current under the 10/1000μs waveform per ANSI/IEEE C62.35. This value is measured with the device mounted on standard FR-4 board per datasheet test conditions and ensures downstream circuitry remains below destructive voltage thresholds during standardized surge events.
Is the P4KE100CA suitable for automotive applications?
Yes, the P4KE100CA is AEC-Q101 qualified and explicitly listed in TSC's automotive-grade product offering. Its DO-204AL package, 175°C maximum junction temperature, and validated performance across temperature cycling, HTRB, and ESD tests make it suitable for under-hood and cabin applications including body control modules and lighting drivers.
How does the bidirectional configuration of the P4KE100CA affect PCB layout?
The P4KE100CA has no polarity marking and functions identically in either orientation, eliminating orientation constraints during placement. Unlike unidirectional TVS diodes, it requires no attention to anode/cathode alignment - simplifying layout, reducing assembly errors, and enabling symmetric placement across differential or AC-coupled lines.
What is the reverse leakage current specification for the P4KE100CA at its working voltage?
At its 81 V working stand-off voltage (VWM), the P4KE100CA exhibits a maximum reverse leakage current (ID) of 1 μA at 25°C. This ultra-low leakage preserves battery life in always-on systems and avoids false triggering in high-impedance sensing circuits, especially critical in automotive and IoT edge nodes.
Does the P4KE100CA meet RoHS and halogen-free compliance requirements?
Yes, the P4KE100CA is RoHS compliant and halogen-free per IEC 61249-2-21. The molding compound contains no brominated flame retardants or chlorine-based additives, and the pure tin-plated leads satisfy J-STD-002 solderability requirements - supporting environmentally regulated end equipment certifications globally.
