Product details
Overview
P6KE16CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in DC power rails and signal lines. It features a 16V nominal breakdown voltage (VBR min/max: 14.4V–17.6V), 12.9V stand-off voltage (VWM), clamps to ≤23.5V at 26A peak surge current, and uses DO-204AC (DO-15) package with AEC-Q101 qualification for automotive-grade reliability.
For engineers reviewing the P6KE16CH datasheet, P6KE16CH pinout, P6KE16CH application, or P6KE16CH equivalent, key selection criteria include its 10/1000μs 600W surge rating, sub-1ps response time from 0V to VBR, <1μA reverse leakage above 10V, and suitability for ESD/inductive switching transient suppression in automotive body electronics and industrial control I/O interfaces.
Technical Context
The P6KE16CH operates as a silicon avalanche diode with unidirectional polarity, triggered when reverse voltage exceeds its 14.4–17.6V breakdown range at 1mA test current. Its low dynamic impedance ensures rapid clamping during fast transients such as ISO 7637-2 pulse 1/2a/5a or IEC 61000-4-5 surges.
Thermal design relies on junction-to-ambient derating per Fig.2: full 600W rating applies only at TA = 25°C, decreasing linearly to ~300W at 75°C ambient. The device sustains 100A non-repetitive forward surge (IFSM) for 8.3ms half-sine, supporting inductive load switching in relay drivers and solenoid controls.
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 |
|---|---|---|---|
| Littelfuse SMAJ16A | Same DO-214AC package, 16V nominal, but 400W rating (vs. 600W); slightly higher clamping voltage (26.0V @ 17.4A) | Lower surge capacity suits cost-sensitive consumer electronics; not AEC-Q101 qualified | Select when automotive qualification is unnecessary and board space allows SMA footprint |
| Vishay 1.5KE16A | Higher power (1500W), same 16V rating, DO-201AD package - larger footprint and higher thermal mass | Better suited for high-energy industrial surge environments (e.g., motor drives), less ideal for compact automotive PCBs | Choose when system-level surge testing requires >600W margin and layout accommodates larger case |
Compared with Littelfuse SMAJ16A and Vishay 1.5KE16A, the P6KE16CH delivers optimal balance of AEC-Q101 compliance, 600W surge capability, and DO-15 form factor - making it preferred for space-constrained automotive and industrial control designs requiring certified reliability.

FAQ
What is the maximum clamping voltage of the P6KE16CH under surge conditions?
The P6KE16CH has a maximum clamping voltage (VC) of 23.5V when subjected to its rated peak pulse current of 26A using the 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream circuitry remains below destructive voltage thresholds during transient events.
Is the P6KE16CH suitable for bidirectional transient protection?
No - the P6KE16CH is a unidirectional TVS diode, indicated by the "H" suffix denoting AEC-Q101 qualification and absence of "C" or "CA" in the part number. For bidirectional protection, select P6KE16CH's counterpart P6KE16C or P6KE16CA, which provide symmetrical clamping in both polarities.
Does the P6KE16CH require a heatsink for 600W surge handling?
No heatsink is required for single-event 600W surge handling, as the energy is dissipated within the silicon junction during the short 1000μs pulse. However, sustained power dissipation must remain below 5W (derated from 75°C ambient), so continuous operation relies on PCB copper thermal mass, not external heatsinking.
How does the P6KE16CH compare to standard Zener diodes for overvoltage protection?
Unlike standard Zeners, the P6KE16CH is optimized for transient suppression - offering faster response (<1ps vs. nanoseconds), higher surge power (600W vs. typically <1W), lower dynamic impedance, and guaranteed clamping performance under standardized 10/1000μs pulses. It is not intended for voltage regulation.
What packaging options are available for the P6KE16CH?
The P6KE16CH is supplied in DO-204AC (DO-15) package with two packing formats: 3,500 units per tape-and-reel (P6KE16CH) and 1,500 units per ammo box (P6KE16CHA0G). Both meet JESD 201 Class 2 whisker resistance and J-STD-002 solderability standards.
