Product details
Overview
P6KE36CA from Taiwan Semiconductor is a bidirectional transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a 36 V nominal breakdown voltage (VBR min/max: 32.4–39.6 V), 600 W peak pulse power rating at 10/1000 µs, clamping voltage of 49.9 V at 12.6 A peak surge current, and operates across –55 °C to +175 °C junction temperature range. It is commonly deployed in automotive body control modules and industrial PLC I/O protection circuits.
For engineers reviewing the P6KE36CA datasheet, P6KE36CA pinout, P6KE36CA application, or P6KE36CA equivalent, key selection criteria include bidirectional clamping performance, DO-15 package compatibility with high-reliability board layouts, AEC-Q101 qualification status, and verified EFT/ESD immunity in 12 V/24 V systems.
Technical Context
The P6KE36CA implements a silicon avalanche diode structure optimized for fast response (<5 ns rise time from 0 V to VBR) and low dynamic impedance under transient stress. Its bidirectional configuration enables symmetrical clamping in AC-coupled or floating signal paths without polarity sensitivity.
It complies with ANSI/IEEE C62.35 for surge testing and delivers stable clamping across ambient temperatures up to 125 °C before derating, supported by a 0.099 %/°C VBR temperature coefficient and <1 µA reverse leakage at 30.8 V standoff voltage.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Nominal Voltage | 36 V - defines rated clamping threshold for system-level surge coordination |
| Breakdown Voltage (VBR) | 32.4–39.6 V at 1 mA - ensures reliable avalanche initiation within defined tolerance band |
| Standoff Voltage (VWM) | 30.8 V - maximum continuous DC or RMS voltage the device blocks without conduction |

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (marked end) | Transient current entry point (bidirectional) | No fixed polarity - either lead conducts during positive or negative surges |
| Cathode (banded end) | Transient current exit point (bidirectional) | Band denotes cathode for unidirectional variants only; irrelevant for CA suffix |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ36CA (Bourns) | Same 36 V VBR range and 600 W rating, but SMB package (surface-mount); lower thermal resistance than DO-15 | Preferred for space-constrained PCBs; requires reflow-compatible layout vs. through-hole assembly | Select SMBJ36CA when board real estate is limited and automated SMT assembly is used. |
| 1.5KE36CA (ON Semiconductor) | Identical DO-15 package and 36 V rating, but 1500 W peak power (1.5 kW); higher IPP (35.1 A) and VC (58.1 V) | Used where higher surge margin is required (e.g., utility meter mains interface), but clamps at higher voltage | Choose 1.5KE36CA only if system design tolerates 58.1 V clamping and needs >600 W headroom. |
Compared with SMBJ36CA and 1.5KE36CA, the P6KE36CA offers optimal balance of proven DO-15 reliability, AEC-Q101 qualification, and precise 49.9 V clamping-making it ideal for cost-sensitive, high-volume automotive and industrial applications where exact 600 W compliance and through-hole manufacturability are prioritized.

FAQ
What does the 'CA' suffix indicate in P6KE36CA?
The 'CA' suffix in P6KE36CA denotes a bidirectional configuration - meaning the device provides symmetrical transient voltage clamping for both positive and negative polarity surges. Unlike unidirectional 'A' variants, P6KE36CA has no anode/cathode orientation requirement in circuit layout and is used where AC signals, differential buses, or floating grounds demand polarity-agnostic protection. This is confirmed in the manufacturer's documentation for bipolar applications.
Is P6KE36CA AEC-Q101 qualified?
Yes, P6KE36CA is AEC-Q101 qualified when ordered with the 'H' suffix (i.e., P6KE36CAH). The base P6KE36CA part meets all electrical and mechanical specifications of the series, but formal AEC-Q101 certification applies only to the H-suffix variant, which undergoes additional stress testing including HTGB, HTRB, and temperature cycling per Rev G requirements. Always verify ordering code for qualification status.
What is the maximum clamping voltage of P6KE36CA and at what current is it specified?
The maximum clamping voltage (VC) of P6KE36CA is 49.9 V, measured at a peak pulse current (IPP) of 12.6 A under the standard 10/1000 µs waveform. This value is guaranteed per the manufacturer's Electrical Specifications table and defines the upper voltage limit imposed on protected circuitry during worst-case transient events.
Can P6KE36CA replace P6KE36A in a design?
No - P6KE36CA and P6KE36A are not interchangeable without circuit review. P6KE36A is unidirectional (anode/cathode sensitive) with 52.0 V clamping at 12.0 A, while P6KE36CA is bidirectional with 49.9 V clamping at 12.6 A. Substituting one for the other may cause incorrect conduction in AC or floating circuits, and the clamping behavior differs in polarity-dependent applications such as DC power rail protection with defined ground reference.
What is the standoff voltage (VWM) and why is it critical for P6KE36CA selection?
The standoff voltage (VWM) of P6KE36CA is 30.8 V - the maximum continuous working voltage the device blocks without significant leakage. It must exceed the system's normal operating voltage (e.g., 24 V DC rail) with margin to avoid false triggering, yet remain low enough to ensure timely clamping during overvoltage events. For a 24 V system, 30.8 V VWM provides ~28 % headroom while enabling effective protection.
