Product details
Overview
P6KE15A 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 15V nominal breakdown voltage, 12.8V stand-off voltage, 21.2V maximum clamping voltage at 29A peak surge current, and low dynamic impedance for effective ESD and lightning-induced transient suppression in automotive and industrial control systems.
For engineers reviewing the P6KE15A datasheet, P6KE15A pinout, P6KE15A application, or P6KE15A equivalent, key selection criteria include clamping voltage margin relative to protected IC VDD, leakage current at operating voltage, surge current capability under 10/1000μs waveform, and AEC-Q101 qualification status for automotive use.
Technical Context
The P6KE15A operates as a unidirectional avalanche diode with fast response time (<1.0ps from 0V to VBR) and low junction capacitance (typ. <100pF at 0V). Its DO-204AC (DO-15) package supports through-hole mounting and meets UL 94V-0 flammability rating with pure tin-plated leads.
It delivers 600W non-repetitive peak pulse power per 10/1000μs waveform, with thermal derating above 25°C ambient and a maximum junction temperature of 175°C. The device exhibits a temperature coefficient of VBR of 0.084%/°C and maintains <1μA reverse leakage at 12.8V.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A | DO-214AA package; 600W rating; 15V nominal; 24.4V clamping at 24.5A | Surface-mount alternative with higher clamping voltage and lower surge current rating | Select when board space constraints require SMD packaging and clamping margin allows 3.2V higher VC |
| 1.5KE15A | DO-201AD package; 1500W rating; same 15V nominal; 23.2V clamping at 64.5A | Higher-power through-hole option with larger footprint and greater surge headroom | Select when system-level surge testing exceeds 600W or requires extended thermal endurance |
Compared with SMBJ15A and 1.5KE15A, the P6KE15A offers optimal balance of axial-leaded manufacturability, 600W surge capability, and tight 21.2V clamping-making it preferred for cost-sensitive, high-volume automotive and industrial power rail designs where DO-15 compatibility and AEC-Q101 qualification (via P6KE15AH) are critical.

FAQ
What is the maximum clamping voltage of the P6KE15A under standard surge conditions?
The P6KE15A has a maximum clamping voltage (VC) of 21.2 V when subjected to a 10/1000μs surge waveform at its rated peak pulse current of 29 A. This value is measured per ANSI/IEEE C62.35 and ensures protected circuits remain within safe operating limits during transient events. The P6KE15A maintains this performance across its full operating temperature range up to 175°C junction temperature.
Is the P6KE15A suitable for automotive applications?
Yes-the P6KE15A is available in an AEC-Q101 qualified version (P6KE15AH) that meets stress test requirements for automotive powertrain and body electronics. While the base P6KE15A part is not automatically qualified, its construction, materials, and electrical parameters align with automotive-grade reliability expectations. Engineers should specify P6KE15AH for production automotive designs requiring formal qualification evidence.
How does the P6KE15A differ from the P6KE15 (non-A) variant?
The P6KE15A features tighter breakdown voltage tolerance (14.3–15.8 V) versus P6KE15 (13.5–16.5 V), resulting in more consistent clamping behavior and improved design margin control. Both share identical package (DO-204AC), power rating (600W), and thermal specs. The P6KE15A also exhibits slightly lower clamping voltage (21.2 V vs. 22.0 V) and higher surge current rating (29 A vs. 28 A), enhancing protection performance in precision 12V systems.
What is the reverse leakage current of the P6KE15A at its stand-off voltage?
The P6KE15A specifies a maximum reverse leakage current (IR) of 1 μA when biased at its rated stand-off voltage of 12.8 V. This ultra-low leakage ensures minimal power loss in always-on 12V systems such as automotive body control modules or industrial sensors operating continuously. Measured at 25°C, leakage remains well below 5 μA even at 100°C junction temperature.
Can the P6KE15A be used in bidirectional configurations?
No-the P6KE15A is a unidirectional TVS diode intended for DC rail protection with defined anode/cathode polarity. For bidirectional protection (e.g., AC lines or differential signals), the P6KE15CA variant must be used. That part shares identical voltage ratings and surge capability but is internally configured as two opposing diodes in series, enabling symmetrical clamping in both directions without polarity sensitivity.
