Product details
Overview
P6KE36 from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 36 V, maximum clamping voltage of 52.0 V at 12.0 A peak surge current, and stand-off voltage of 29.1 V - enabling robust ESD and lightning-induced surge suppression in automotive and industrial control circuits.
For engineers reviewing the P6KE36 datasheet, P6KE36 pinout, P6KE36 application, or P6KE36 equivalent, key selection criteria include its DO-204AC (DO-15) axial package, 175 °C junction temperature rating, low dynamic impedance, and AEC-Q101 qualification option (P6KE36H), critical for automotive body electronics and power supply input stages.
Technical Context
The P6KE36 operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its specified breakdown range (32.4–39.6 V at 1 mA test current). Its clamping action limits transient energy to ≤52.0 V under 10/1000 µs waveform surges up to 600 W, with sub-nanosecond response time (<1.0 ps from 0 V to VBR) ensuring protection before downstream IC damage occurs.
Thermal performance is defined by a 175 °C maximum junction temperature and derated pulse power above 25 °C ambient per Fig.2. The device exhibits <1 µA reverse leakage at 29.1 V and a temperature coefficient of VBR of 0.099 %/°C, supporting stable operation across extended industrial temperature ranges.
Key Specifications
| Parameter | Value and Actual Design Meaning |

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 SMAJ36A | Same DO-214AC (SMA) package; 36 V nominal, 58.1 V clamping at 10.3 A; 400 W rating | Lower power rating and higher clamping voltage reduce margin for high-energy surges | Select when board space constraints favor surface-mount and surge threat level is ≤IEC 61000-4-5 Level 3 |
| ON Semiconductor 1.5KE36A | Same DO-201AD (DO-201) package; 36 V nominal, 58.1 V clamping at 10.3 A; 1500 W rating | Higher surge capability but larger footprint and higher leakage (5 µA @ 29.1 V) | Select when legacy designs require drop-in replacement with enhanced surge headroom and thermal mass |
Compared with P6KE36, SMAJ36A offers SMT compatibility at reduced surge robustness, while 1.5KE36A provides higher power handling in a larger through-hole package - choice depends on PCB layout, thermal management, and required immunity level.

FAQ
What is the maximum clamping voltage of the P6KE36 under surge conditions?
The P6KE36 has a maximum clamping voltage (VC) of 52.0 V when subjected to a 12.0 A peak pulse current with a 10/1000 µs waveform. This value is measured per ANSI/IEEE C62.35 and defines the upper voltage limit imposed on protected circuitry during transient events - a critical parameter for ensuring downstream ICs remain within their absolute maximum ratings.
Is the P6KE36 unidirectional or bidirectional, and how is polarity identified?
The P6KE36 is a unidirectional TVS diode, intended for DC line protection where polarity is fixed. Polarity is marked by a cathode band on the DO-204AC (DO-15) package body - the banded end connects to the protected line, while the anode connects to ground. Bidirectional variants use "CA" suffixes (e.g., P6KE36CA), which the P6KE36 does not carry.
Does the P6KE36 meet automotive qualification standards?
The base P6KE36 is not AEC-Q101 qualified; however, the P6KE36H variant - identifiable by the "H" suffix in the ordering code - is fully AEC-Q101 qualified and tested for automotive applications including temperature cycling, high-temperature reverse bias, and ESD. Always verify the full part number suffix when selecting for automotive use.
What is the reverse leakage current specification for the P6KE36 at its stand-off voltage?
At its maximum stand-off voltage of 29.1 V and ambient temperature of 25 °C, the P6KE36 exhibits a maximum reverse leakage current (ID) of 1 µA. This low leakage ensures minimal power loss and avoids unintended loading of sensitive 24 V or 36 V monitoring circuits in always-on systems such as automotive ECUs or smart meters.
Can the P6KE36 be used in parallel for higher surge current handling?
No - the P6KE36 is not recommended for parallel operation due to mismatch in breakdown voltage (32.4–39.6 V range), which causes uneven current sharing and potential thermal runaway. For higher surge capability, select a higher-rated device like the 1.5KE36A or implement staged protection with upstream fusing and downstream low-capacitance TVS arrays instead of paralleling P6KE36 units.
