Product details
Overview
P6KE75CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage protection in power supplies and automotive electronics. It features a nominal breakdown voltage of 75 V, clamps transients to ≤108 V at 5.8 A peak surge current, and delivers sub-nanosecond response time (<1.0 ps) to protect downstream ICs from ESD and lightning-induced surges.
For engineers reviewing the P6KE75CH datasheet, P6KE75CH pinout, P6KE75CH application, or P6KE75CH equivalent, key selection criteria include its DO-204AC (DO-15) axial package, AEC-Q101 qualification, 60.7 V stand-off voltage, <1 μA reverse leakage above 10 V, and suitability for 12 V/24 V automotive power rail protection.
Technical Context
The P6KE75CH operates as a unidirectional avalanche diode with a single-die DO-204AC construction, optimized for high-energy 10/1000 µs waveform suppression. Its junction temperature range spans −55 °C to +175 °C, and it maintains stable clamping performance across ambient temperatures up to 75 °C with derated surge capability.
Electrical behavior is defined by a 1 mA test current, 0.105 %/°C temperature coefficient of VBR, and a maximum dynamic impedance derived from the 108 V clamping voltage at 5.8 A. Polarity is marked by a cathode band, and terminals are pure tin-plated per J-STD-002 solderability standards.

IC Role / Device Role: Unidirectional TVS placed between GPIO and ground near connector entry point. Use Value: Provides IEC 61000-4-2 Level 4 (±15 kV air, ±8 kV contact) immunity without adding capacitance that degrades signal rise time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ75A | Bidirectional; 75 V standoff; DO-214AA package; 600 W rating | Requires no polarity consideration but lacks AEC-Q101 qualification | Select when bidirectional protection is needed and automotive qualification is not required |
| 1.5KE75A | Same unidirectional function; DO-201AD package; 1500 W rating; higher clamping (121 V) | Higher surge capacity but larger footprint and slower thermal recovery | Select when system requires >600 W surge margin and board space permits larger package |
Compared with SMBJ75A and 1.5KE75A, the P6KE75CH offers AEC-Q101 validation in a compact DO-15 form factor with tighter clamping (108 V vs. 121 V), making it optimal for space-constrained automotive modules where reliability and voltage headroom are critical.

FAQ
What is the clamping voltage of the P6KE75CH under maximum rated surge current?
The P6KE75CH clamps to a maximum of 108 V when subjected to its rated peak pulse current of 5.8 A (10/1000 µs waveform). This value is measured at the device terminals and represents the upper voltage limit imposed on protected circuitry during transient events, ensuring downstream components remain within safe operating voltage margins.
Is the P6KE75CH suitable for automotive applications?
Yes, the P6KE75CH is AEC-Q101 qualified and explicitly rated for automotive use. Its −55 °C to +175 °C junction temperature range, DO-204AC mechanical robustness, and compliance with ISO 7637-2 pulse immunity requirements make it appropriate for engine control units, body electronics, and infotainment power rails where reliability under thermal and electrical stress is mandatory.
How does the P6KE75CH differ from the P6KE75A variant?
The P6KE75CH uses the "H" suffix to denote AEC-Q101 qualification and is manufactured to automotive-grade process controls, whereas the P6KE75A is an industrial-grade version with identical electrical specs (67.5–78.8 V VBR, 103 V clamping) but no automotive qualification. The "CH" variant also carries green compound marking and specific date-code formatting per TSC's automotive traceability requirements.
What is the maximum reverse leakage current for the P6KE75CH at its stand-off voltage?
At its rated stand-off voltage of 60.7 V, the P6KE75CH exhibits a maximum reverse leakage current of 1 µA at 25 °C. This low leakage ensures minimal power loss in always-on circuits and preserves signal integrity in high-impedance sensing paths, such as those found in battery monitoring or precision voltage reference designs.
Can the P6KE75CH be used in bidirectional configurations?
No - the P6KE75CH is a unidirectional TVS diode, identified by its cathode band marking and specified breakdown behavior only in reverse bias. For bidirectional protection, engineers must select the P6KE75CA variant (if available) or a dedicated bidirectional part like SMBJ75CA; using P6KE75CH in reverse-biased mode will not provide symmetrical clamping.
