Product details
Overview
P6KE10CH 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 10V nominal breakdown voltage (VBR min/max: 9.0–11.0V), 8.1V stand-off voltage (VWM), clamps to ≤15.0V at 42A peak surge current, and delivers sub-1ps response time from 0V to VBR - ideal for safeguarding automotive ECUs against ISO 7637-2 pulse 1/2a transients.
For engineers reviewing the P6KE10CH datasheet, P6KE10CH pinout, P6KE10CH application, or P6KE10CH equivalent, key selection criteria include its AEC-Q101 qualification, DO-15 package compatibility with high-density PCB layouts, low dynamic impedance (<0.3Ω typical), and guaranteed clamping performance under 10/1000μs surge waveforms per IEC 61000-4-5.
Technical Context
The P6KE10CH operates as a silicon avalanche diode with unidirectional polarity and single-die construction in a DO-204AC (DO-15) package. Its junction exhibits low dynamic impedance (typically <0.3Ω) and temperature coefficient of VBR at +0.073%/°C, enabling stable clamping across -55°C to +175°C operating range.
It meets UL 94V-0 flammability rating, supports 100A non-repetitive forward surge (IFSM), and maintains reverse leakage <1μA at 8.1V - critical for low-power sensor interfaces and always-on automotive modules where standby current integrity is essential.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VWM (Stand-off Voltage) | 8.1 V - Maximum continuous DC or RMS voltage the device blocks without significant leakage; ensures no false triggering in 5–8V logic-supplied systems. |
| VBR (Breakdown Voltage) | 9.0–11.0 V @ 1 mA - Avalanche onset range defining reliable turn-on threshold; tightly controlled for consistent protection timing. |
| VC @ IPPM (Clamping Voltage) | 15.0 V @ 42 A - Peak voltage seen by protected circuit during 10/1000μs surge; limits stress on downstream 16V-rated ICs. |
| PPK (Peak Pulse Power) | 600 W - Sustained energy absorption capability under standardized 10/1000μs waveform; validates robustness against load dump events. |
| IR @ VWM (Reverse Leakage) | <1 μA - Negligible standby current draw; preserves battery life in automotive body control modules and IoT edge sensors. |
| TJ max (Junction Temperature) | +175 °C - Enables operation in under-hood environments and industrial motor drives without thermal derating penalties. |
| Response Time | <1.0 ps - Near-instantaneous conduction onset from 0V to VBR; prevents nanosecond-scale ESD-induced latch-up in high-speed interfaces. |
Pinout & Package
Package: DO-204AC (DO-15), axial-leaded, epoxy-molded case with cathode band marking. Leads are pure tin-plated, solderable per J-STD-002, and meet JESD 201 Class 2 whisker resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (unmarked end) | Current entry point during forward conduction | Connected to protected line's low-side return path; enables bidirectional surge suppression when used with complementary devices. |
| Cathode (banded end) | Avalanche conduction terminal during reverse overvoltage | Connected to system ground or reference rail; defines unidirectional clamping direction and polarity-sensitive placement. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ10A | Same 10V VBR range but SMB package (surface-mount); lower 600W rating applies only at 25°C (derates faster above 75°C). | Preferred for automated SMT assembly; unsuitable for through-hole legacy boards or high-temperature under-hood zones exceeding 125°C ambient. | Select SMBJ10A only when board space is constrained and thermal management ensures TJ ≤125°C. |
| 1.5KE10C | Same DO-15 package and unidirectional function, but 1.5kW rating (10/1000μs); higher clamping voltage (17.5V @ 87A) and larger physical size. | Better suited for 24V industrial systems requiring higher surge margin; overkill for 12V automotive use due to excessive VC and layout footprint. | Choose 1.5KE10C only when system-level testing confirms need for >600W headroom and PCB accommodates larger body dimensions. |
Compared with SMBJ10A and 1.5KE10C, the P6KE10CH uniquely balances AEC-Q101 qualification, DO-15 through-hole compatibility, and precise 15.0V clamping - making it the optimal choice for cost-sensitive, thermally demanding automotive and industrial replacements where reliability and form-factor alignment are non-negotiable.

FAQ
What is the maximum clamping voltage of the P6KE10CH under standard surge conditions?
The P6KE10CH clamps to a maximum of 15.0 V when subjected to a 10/1000μs surge waveform at 42 A peak current (IPPM), as specified in the Electrical Specifications table. This value is measured at TA = 25°C and remains stable across its full -55°C to +175°C junction temperature range, ensuring predictable protection behavior in under-hood automotive applications where the P6KE10CH is commonly deployed.
Is the P6KE10CH suitable for bidirectional transient suppression?
No, the P6KE10CH is a unidirectional TVS diode, indicated by its "H" suffix and cathode band marking. It conducts only during reverse-biased overvoltage events. For bidirectional protection, Taiwan Semiconductor offers the P6KE10CA variant - which shares identical VBR, VWM, and clamping specs but uses symmetrical avalanche structure. Using P6KE10CH in bidirectional configurations risks failure during positive-going transients.
Does the P6KE10CH meet automotive qualification standards?
Yes, the "H" suffix in P6KE10CH explicitly denotes AEC-Q101 qualification per Version P2203 documentation. It has passed stress tests including high-temperature reverse bias (HTRB), temperature cycling, and mechanical shock - validating its suitability for engine control units, body electronics, and ADAS power supplies where automotive-grade reliability is mandatory.
What is the lead finish and solderability specification for the P6KE10CH?
The P6KE10CH features pure tin-plated leads compliant with J-STD-002 for solderability, and its DO-204AC (DO-15) package meets JESD 201 Class 2 whisker resistance requirements. The terminals are compatible with standard SnPb and lead-free reflow profiles, supporting both wave soldering and hand-soldering processes without dewetting or embrittlement concerns.
How does the P6KE10CH compare to the P6KE10A in terms of electrical performance?
The P6KE10CH and P6KE10A share identical nominal voltage (10V), VBR range (9.5–10.5V), VWM (8.55V), and clamping voltage (14.5V @ 43A). The key distinction is qualification: P6KE10CH is AEC-Q101 certified and marked with "H", whereas P6KE10A lacks automotive qualification. Both use DO-15 packaging and exhibit <1μA leakage at rated VWM - making P6KE10CH the required choice for automotive deployments.
