Taiwan Semiconductor Corporation P6KE100AH

Overview

P6KE100AH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a 100V nominal breakdown voltage (VBR min/max: 90–110V), 81V stand-off voltage (VWM), clamps to ≤137V at 4.5A peak surge current, and operates across –55°C to +175°C junction temperature range - deployed in automotive power supply input stages and industrial sensor interfaces.

For engineers reviewing the P6KE100AH datasheet, P6KE100AH pinout, P6KE100AH application, or P6KE100AH equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) axial package, 1μA max reverse leakage at 85.5V, 10/1000μs waveform surge rating, and polarity-marked cathode band for unidirectional operation.

Technical Context

The P6KE100AH implements a silicon avalanche diode structure optimized for fast transient response (<1.0ps rise time from 0V to VBR) and low dynamic impedance to limit voltage overshoot during ESD or lightning-induced surges. Its unidirectional configuration enables asymmetric clamping - conducting only in reverse bias above VBR while blocking forward current up to 100A IFSM.

Thermal design is supported by a 175°C maximum junction temperature and derating curves per Fig.2, with steady-state power dissipation of 5W at 75°C ambient when mounted on 5×5 mm copper pads. The device complies with ANSI/IEEE C62.35 for surge testing and meets UL 94V-0 flammability requirements in its molded DO-204AC case.

Key Specifications

Pinout & Package

DO-204AC (DO-15) axial package with cathode band marking; leads are pure tin-plated and solderable per J-STD-002. Polarity is unidirectional: cathode (banded end) connects to protected circuit's higher-potential side (e.g., VBUS), anode to ground or lower-potential return path.

FAQ

What is the clamping voltage of the P6KE100AH under standard 10/1000μs surge conditions?

The P6KE100AH clamps to a maximum of 137 V when subjected to its rated 4.5 A peak pulse current (IPP) using the 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and represents the upper bound of voltage seen by downstream circuitry during a defined transient event - critical for ensuring protected ICs remain within absolute maximum ratings. The P6KE100AH achieves this with minimal overshoot due to its low dynamic impedance.

Is the P6KE100AH suitable for bidirectional transient protection?

No, the P6KE100AH is a unidirectional TVS diode and is not rated for bidirectional operation. Its electrical specifications - including VBR, VWM, and clamping behavior - apply only in reverse-bias mode. For bidirectional protection, TSC offers the P6KE100CA variant (with 'C' or 'CA' suffix), which provides symmetrical clamping in both polarities. Using P6KE100AH in bidirectional configurations risks failure during positive transients on the anode.

Does the P6KE100AH meet automotive qualification standards?

Yes, the 'H' suffix in P6KE100AH explicitly denotes AEC-Q101 qualification per the manufacturer's ordering information. This includes stress testing for temperature cycling, highly accelerated life testing (HALT), and mechanical robustness - confirming suitability for under-hood and cabin applications where reliability across –40°C to +125°C ambient is mandatory. The P6KE100AH is excluded from the non-AEC-Q101 subset (e.g., P6KE6V8A–P6KE9V1A).

What is the maximum reverse leakage current specified for the P6KE100AH?

The P6KE100AH specifies a maximum reverse leakage current (ID) of 1 μA when biased at its rated stand-off voltage of 85.5 V (VWM) and tested at 25°C. This ultra-low leakage ensures minimal power loss and avoids interference with high-impedance monitoring circuits - such as those found in battery management or precision sensor front-ends - where even nanoamp-level currents could affect accuracy.

How does the DO-204AC (DO-15) package of the P6KE100AH impact thermal performance?

The DO-204AC (DO-15) package of the P6KE100AH delivers 5 W steady-state power dissipation at 75°C ambient when mounted on 5 × 5 mm copper pads per lead, per datasheet Fig.2 derating curve. Its axial lead geometry supports manual or wave soldering and provides mechanical stability in vibration-prone environments, though thermal resistance is higher than surface-mount alternatives - requiring careful PCB copper area allocation for sustained surge duty cycles.
