Product details
Overview
P6KE27CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-level overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 27 V, clamps transients to ≤39.1 V at 16 A peak surge current, exhibits <1 μA reverse leakage at 21.8 V stand-off voltage, and uses DO-204AC (DO-15) package for through-hole mounting in automotive and industrial power supply circuits.
For engineers reviewing the P6KE27CH datasheet, P6KE27CH pinout, P6KE27CH application, or P6KE27CH equivalent, key selection criteria include its AEC-Q101 qualification, 10/1000 µs waveform surge rating, low dynamic impedance, fast sub-nanosecond response time, and compatibility with high-reliability automotive ECU and body control module designs.
Technical Context
The P6KE27CH operates as a unidirectional avalanche diode, triggering conduction when reverse voltage exceeds its minimum breakdown voltage of 24.3 V (tested at 1 mA). Its clamping action limits transient energy to ≤39.1 V at 16 A peak pulse current under standardized 10/1000 µs waveform conditions, enabling robust protection of downstream MOSFETs, microcontrollers, and CAN transceivers.
Thermal performance is defined by a maximum junction temperature of +175 °C and derating above 25 °C ambient per Fig.2; it sustains 5 W steady-state dissipation at 75 °C with 9.5 mm lead length, and supports 100 A non-repetitive forward surge (8.3 ms half-sine) - critical for inductive load switching immunity in 12 V/24 V vehicle systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power | 600 W at 10/1000 µs waveform - defines maximum transient energy absorption without failure |
| Breakdown Voltage VBR | 24.3–29.7 V at 1 mA - ensures reliable turn-on before sensitive ICs exceed absolute maximum ratings |
| Clamping Voltage VC | ≤39.1 V at 16 A IPP - guarantees protected circuit sees no more than this voltage during surge event |
| Stand-Off Voltage VWM | 21.8 V - maximum continuous DC operating voltage before leakage exceeds 1 µA |
| Junction Temperature | −55 to +175 °C - supports operation in under-hood automotive environments and industrial enclosures |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with tin-plated leads, UL 94V-0 molding |
| AEC-Q101 Qualified | Yes (H suffix) - validated for automotive-grade reliability including temperature cycling, HTRB, and ESD |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002; polarity is unidirectional, with cathode indicated by band.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Ground reference terminal | Connected to system ground or low-side return path; conducts surge current to earth during clamping |
| Cathode | Protected line input | Connected to line being protected (e.g., battery rail, sensor supply); blocks normal operation, avalanches during overvoltage |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive electronics including engine control units and ADAS power domains |
| Low dynamic impedance | Enables tighter clamping voltage margin and faster voltage stabilization during fast-rising transients |
| Sub-1 ns response time | Typically <1.0 ps from 0 V to VBR - protects against ESD and EFT events before IC internal protection triggers |
| UL 94V-0 flammability rating | Molding compound meets safety standard for fire resistance in enclosed electronic assemblies |
| Halogen-free construction | Complies with IEC 61249-2-21 - supports RoHS-compliant manufacturing and end-of-life recycling |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ24A | Lower peak power (600 W same), but lower VBR (24–26.7 V), higher clamping (38.9 V), DO-214AA package | SMT-only layout; lacks AEC-Q101 qualification in standard grade | Select when board space is constrained and automotive qualification is not required |
| 1.5KE27C | Same DO-204AC package, but bidirectional configuration (±27 V), higher clamping (45.7 V), no AEC-Q101 option | Supports AC-coupled or floating signal lines where polarity reversal may occur | Choose only for bipolar signal paths; not suitable as direct replacement for unidirectional DC rail protection |
Compared with SMBJ24A and 1.5KE27C, the P6KE27CH uniquely combines AEC-Q101 qualification, unidirectional DO-204AC packaging, and optimized clamping for 12–24 V automotive power domains - making it the preferred choice where reliability, regulatory compliance, and through-hole manufacturability are jointly required.

FAQ
What does the "H" suffix in P6KE27CH signify?
The "H" suffix in P6KE27CH indicates full AEC-Q101 qualification - verified through temperature cycling, highly accelerated life testing (HALT), and ESD robustness tests per automotive reliability standards. This distinguishes it from non-H variants like P6KE27C, which lack formal automotive qualification despite identical electrical specs.
Is P6KE27CH unidirectional or bidirectional?
P6KE27CH is a unidirectional TVS diode, configured with anode and cathode terminals and marked with a cathode band. It protects against positive transients on the cathode side relative to anode (ground), and blocks reverse voltage during normal operation - unlike bidirectional types such as P6KE27CA.
What is the maximum clamping voltage for P6KE27CH at rated surge current?
The maximum clamping voltage VC for P6KE27CH is 39.1 V at 16 A peak pulse current (IPP), measured under the standardized 10/1000 µs double-exponential waveform. This value is guaranteed across the full operating temperature range and forms the basis for downstream IC voltage margining.
Can P6KE27CH be used in surface-mount designs?
No - P6KE27CH uses the DO-204AC (DO-15) axial-leaded through-hole package and is not compatible with SMT reflow processes. For surface-mount equivalents, consider SMBJ24A (DO-214AA) or SMCJ24A (DO-214AB), though neither carries AEC-Q101 certification in standard grades.
How does P6KE27CH handle repetitive surge events?
P6KE27CH is rated for non-repetitive surges per Fig.3; repetitive operation requires derating per Fig.2 - e.g., at 75 °C ambient, peak pulse power drops to ~400 W. For frequent transients, thermal design must ensure junction temperature remains ≤175 °C, and duty cycle must stay below 4 pulses/minute per datasheet Note 3.
