Product details
Overview
P6KE15CAH from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in automotive and industrial power rails. It features a nominal breakdown voltage of 15 V, clamps transients to ≤22.0 V at 28.0 A peak surge current, and delivers sub-5 ns response time with <1 μA leakage above 12.1 V stand-off voltage - deployed in DC power input stages of automotive ECUs and industrial PLCs.
For engineers reviewing the P6KE15CAH datasheet, P6KE15CAH pinout, P6KE15CAH application, or P6KE15CAH equivalent, key selection criteria include its AEC-Q101 qualification, DO-204AC (DO-15) package compatibility, bidirectional clamping symmetry, 175°C junction rating, and compliance with IEC 61000-4-4/5 EFT/surge immunity requirements.
Technical Context
The P6KE15CAH operates as a silicon avalanche diode configured in bidirectional (symmetrical) mode, enabling identical clamping behavior for positive and negative transients without polarity sensitivity. Its low dynamic impedance and fast 5.0 ns response ensure effective suppression of fast-rising ESD and EFT events per IEC 61000-4-2 and -4-4 standards.
Rated for 600 W non-repetitive peak pulse power at the 10/1000 µs waveform, it sustains up to 100 A forward surge current (IFSM) and maintains stable VBR (13.5–16.5 V) with a temperature coefficient of 0.084 %/°C - critical for thermal stability across automotive under-hood temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W at 10/1000 µs - supports high-energy surge immunity in 12 V automotive systems |
| Breakdown Voltage VBR | 13.5–16.5 V @ 1 mA - defines precise clamping onset threshold for 15 V nominal rail protection |
| Clamping Voltage VC | ≤22.0 V @ 28.0 A IPP - ensures downstream ICs see no more than 22 V during worst-case surge |
| Stand-Off Voltage VWM | 12.1 V - allows reliable operation below clamping threshold with minimal leakage (<1 µA) |
| Response Time | 5.0 ns (bidirectional) - enables suppression of nanosecond-scale ESD/EFT transients |
| Junction Temperature | -55 °C to +175 °C - certified for under-hood automotive environments and industrial thermal cycling |
| AEC-Q101 Qualified | Yes - validated for automotive-grade reliability including temperature cycling, HTRB, and HTGB |
Pinout & Package

Applications
| Automotive Body Control Module (BCM) | Industrial PLC Digital Input Module |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA | Same 15 V nominal, 600 W rating, but SMB package (surface-mount); lower IFSM (100 A vs. P6KE15CAH's 100 A - identical), slightly higher VC (24.4 V vs. 22.0 V) | Requires PCB rework for SMT placement; better suited for space-constrained designs where through-hole is impractical | Select SMBJ15CA only if board real estate or automated assembly mandates SMT - verify thermal pad design for 5 W dissipation |
| 1.5KE15CA | Same DO-204AC package and 15 V rating, but 1.5 kW peak power (1500 W); higher VC (23.2 V), larger physical size, higher leakage (5 μA @ VWM) | Over-specified for 600 W use cases; introduces unnecessary cost and board area unless legacy 1.5 kW requirement exists | Choose 1.5KE15CA only when system-level surge testing exceeds 600 W - otherwise P6KE15CAH offers optimal cost/performance balance |
Compared with SMBJ15CA and 1.5KE15CA, the P6KE15CAH delivers the most balanced combination of AEC-Q101 qualification, compact DO-15 footprint, lowest clamping voltage (22.0 V), and verified 600 W capability - making it the preferred choice for new automotive and industrial designs targeting IPC Class 3 reliability without over-engineering.

FAQ
What does the "CA" suffix indicate in P6KE15CAH?
The "CA" suffix in P6KE15CAH denotes bidirectional configuration - meaning the device provides symmetrical clamping for both positive and negative transients without polarity dependence. This distinguishes it from unidirectional variants (e.g., P6KE15A), and is essential for protecting AC-coupled or floating signal lines. The P6KE15CAH maintains identical VBR (13.5–16.5 V) and VC (≤22.0 V) in both directions.
Is P6KE15CAH suitable for ISO 7637-2 Pulse 5a (load dump) protection?
Yes, the P6KE15CAH is rated for 600 W at the 10/1000 µs waveform and operates up to 175 °C - meeting key requirements for ISO 7637-2 Pulse 5a suppression in 12 V automotive systems. Its 22.0 V clamping voltage ensures downstream regulators remain within safe operating limits during 100 V/400 ms transients, provided proper PCB layout and thermal management are implemented for the P6KE15CAH.
How does the "H" suffix affect P6KE15CAH's qualification status?
The "H" suffix in P6KE15CAH explicitly indicates AEC-Q101 qualification - confirmed by Taiwan Semiconductor's certification documentation. This includes stress testing for temperature cycling, high-temperature reverse bias, and highly accelerated life testing. Unlike standard P6KE15CA parts, the P6KE15CAH is fully qualified for automotive under-hood applications per AEC-Q101 Rev D.
What is the maximum continuous power dissipation for P6KE15CAH at 75°C ambient?
The P6KE15CAH has a steady-state power dissipation (PD) rating of 5 W at TA = 75 °C when mounted on 5 × 5 mm copper pads per terminal. This value is derated linearly above 75 °C and must be respected in thermally constrained layouts. Exceeding this limit risks thermal runaway or premature failure - especially critical in sealed automotive enclosures where the P6KE15CAH operates near its 175 °C TJ max.
Can P6KE15CAH replace P6KE15A in an existing design?
No - P6KE15CAH is bidirectional while P6KE15A is unidirectional, so direct substitution requires circuit review. The P6KE15CAH clamps in both directions with symmetrical VBR and VC, whereas P6KE15A only protects against reverse-polarity transients. Replacing P6KE15A with P6KE15CAH may cause unintended conduction in DC-biased rails; verify polarity requirements and clamping behavior before redesigning with P6KE15CAH.
