Product details
Overview
P6KE16A 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 16V nominal breakdown voltage, 13.6V stand-off voltage, 22.5V clamping voltage at 28A peak surge current, and low dynamic impedance for fast response to ESD and lightning-induced transients in automotive and industrial control systems.
For engineers reviewing the P6KE16A datasheet, P6KE16A pinout, P6KE16A application, or P6KE16A equivalent, this device is selected for robust transient immunity in 12V/24V embedded power supplies, I/O interface protection, and AEC-Q101-compliant automotive subsystems where sub-1ns response time and <1μA leakage above 10V are critical.
Technical Context
The P6KE16A operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its 15.2–16.8V breakdown range at 1mA test current. Its DO-204AC (DO-15) package supports lead-free soldering and meets JESD201 Class 2 whisker resistance.
It delivers 600W non-repetitive peak pulse power under 10/1000μs waveform, with clamping voltage limited to 22.5V at 28A IPP, enabling reliable protection of downstream MOSFETs, microcontrollers, and CAN transceivers without overstressing protected circuitry.

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 P6KE16A | Identical electrical specs and DO-15 package; UL E326243 certified; same 15.2–16.8V VBR range | No functional difference; validated in same AEC-Q101 test conditions | Drop-in replacement with identical thermal and mechanical footprint |
| ON Semiconductor 1.5KE16A | Same 16V nominal rating but 1.5kW peak power rating; larger DO-201AD package (5.2mm body length vs. DO-15's 4.2mm) | Higher surge margin for infrequent extreme events; requires PCB layout change due to longer body and different lead spacing | Select when 1.5kW surge headroom is required and board space allows larger package |
Compared with Littelfuse P6KE16A, the Taiwan Semiconductor P6KE16A offers identical performance and qualification in the same DO-15 footprint; versus ON Semiconductor 1.5KE16A, it trades peak power headroom for smaller size and lower cost in standard 600W applications.

FAQ
What is the clamping voltage of P6KE16A at its rated peak surge current?
The P6KE16A has a maximum clamping voltage (VC) of 22.5 V when subjected to its rated peak surge current of 28 A under the standard 10/1000 μs waveform. This value ensures protected circuits remain below critical overvoltage thresholds during transient events, and is measured per ANSI/IEEE C62.35 standards.
Is P6KE16A suitable for automotive applications requiring AEC-Q101 qualification?
Yes, the P6KE16A is AEC-Q101 qualified when ordered with the "H" suffix (e.g., P6KE16AH). The base P6KE16A part meets all electrical and reliability requirements of AEC-Q101, including temperature cycling, humidity bias, and mechanical shock testing, making it suitable for under-hood and cabin ECUs.
What is the standoff voltage (VWM) and why does it matter for P6KE16A placement?
The P6KE16A has a maximum standoff voltage (VWM) of 13.6 V, meaning it remains non-conductive up to this reverse voltage level. This allows safe integration on 12V nominal rails without leakage-related power loss, and ensures the device only activates during actual overvoltage events-not during normal operation or minor ripple.
How does the DO-204AC (DO-15) package of P6KE16A affect thermal performance?
The DO-204AC (DO-15) package of P6KE16A provides a thermal resistance (RθJA) of approximately 70°C/W when mounted on 5 × 5 mm copper pads per lead. This enables effective heat dissipation during repetitive surge events and supports continuous operation up to +175°C junction temperature, critical for engine bay and industrial control environments.
Can P6KE16A be used in bidirectional configurations?
No, the P6KE16A is a unidirectional TVS diode and must be used with correct polarity-cathode toward the protected line. For bidirectional protection, select the CA-suffixed variant (e.g., P6KE16CA), which uses a back-to-back diode configuration and exhibits symmetric breakdown in both directions.
