Product details
Overview
P6KE15CH from Taiwan Semiconductor is a unidirectional 600W transient voltage suppressor (TVS) diode designed for primary-side overvoltage clamping in DC power rails and signal lines. It features a 15V nominal breakdown voltage (VBR min/max: 13.5V–16.5V), 12.1V stand-off voltage (VWM), 22.0V maximum clamping voltage at 28A peak surge current, and operates across –55°C to +175°C junction temperature range. It is AEC-Q101 qualified and housed in DO-204AC (DO-15) package for automotive power supply protection.
For engineers reviewing the P6KE15CH datasheet, P6KE15CH pinout, P6KE15CH application, or P6KE15CH equivalent, this device serves as a fast-response, low-leakage (≤1μA @ 12.1V), high-surge-capability TVS for ESD and lightning-induced transients in 12V/24V automotive subsystems, industrial I/O interfaces, and LED driver input stages.
Technical Context
The P6KE15CH employs a planar silicon junction structure optimized for low dynamic impedance and sub-nanosecond response (<1.0ps from 0V to VBR). Its unidirectional configuration enables asymmetric clamping-blocking reverse conduction while clamping positive transients above VBR with minimal overshoot.
It complies with ANSI/IEEE C62.35 for transient suppression and supports 10/1000μs surge waveforms up to 600W. The device's 0.084%/°C VBR temperature coefficient ensures stable clamping threshold across wide ambient ranges, critical for under-hood automotive environments.
Key Specifications

|---|---|
| VWM | 12.1 V - Maximum continuous reverse operating voltage before leakage exceeds 1 μA; defines safe DC rail margin below clamping onset. |
| VBR (min/max) | 13.5 V / 16.5 V - Breakdown occurs within this band at 1 mA test current; sets precise overvoltage trip window. |
| VC @ IPP | 22.0 V @ 28 A - Clamped voltage during 10/1000μs surge; determines maximum stress imposed on downstream ICs. |
| PPK | 600 W - Peak pulse power handling per single 10/1000μs event; enables robust protection against ISO 7637-2 Pulse 1/2a/5a transients. |
| IR @ VWM | <1 μA - Ultra-low reverse leakage ensures negligible standby power loss and no measurable loading on 12V sensor rails. |
| TJ max | +175 °C - Extended junction temperature rating supports placement near heat sources (e.g., engine control units, power converters). |
| AEC-Q101 | Qualified - Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114. |

Use Scenario: 12V battery feed to engine control unit (ECU) exposed to load dump (ISO 7637-2 Pulse 5a) and alternator ripple. IC Role / Device Role / Timing Role: Primary clamping element placed directly at ECU input connector to shunt surge energy before it reaches LDO regulators and MCU power pins. Use Value: Clamps transients to 22.0V, staying well below the 28V absolute maximum rating of common automotive MCUs and ensuring uninterrupted operation during cranking and load dump events. |
Use Scenario: 4–20mA current loop input of PLC analog module subjected to field-wiring ESD and inductive kickback from solenoid disconnects. IC Role / Device Role / Timing Role: Unidirectional TVS placed across loop terminals to clamp positive transients while allowing normal 24V loop bias to pass unaffected. Use Value: Sub-1.0ps response prevents ESD-induced latch-up in op-amp front-end circuitry; 12.1V VWM permits full 24V loop compliance with margin. |
| LED Driver Input Stage Protection | Automotive CAN Transceiver Protection |
|
Use Scenario: Input stage of constant-current LED driver for exterior lighting, exposed to jump-start surges and reverse battery connection. IC Role / Device Role / Timing Role: First-line defense on DC input rail, absorbing 600W pulses and limiting voltage to 22.0V to protect upstream MOSFET gate drivers and controller ICs. Use Value: Withstands 100A forward surge (IFSM) during reverse polarity events, eliminating need for separate series diode in cost-sensitive headlamp modules. |
Use Scenario: CAN_H/CAN_L lines of automotive infotainment gateway exposed to ESD (IEC 61000-4-2 ±15kV) and coupled transients from nearby high-power switching. IC Role / Device Role / Timing Role: Bidirectional clamping not applicable here-P6KE15CH used on 12V supply rail feeding CAN transceiver, not on data lines. Use Value: Ensures clean 12V VCC to CAN PHY by clamping supply rail transients to 22.0V, preventing transceiver reset or bus-off conditions during electrical fast transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15A (Bourns) | Same 15V nominal, bidirectional; 600W rating; SMB package (surface-mount); lower VC = 24.4V @ 24.7A. | Requires PCB rework for SMD layout; better suited for space-constrained modules where through-hole DO-15 is impractical. | Select SMBJ15A only if board real estate is constrained and automated assembly is preferred; P6KE15CH remains optimal for manual repair, high-reliability through-hole mounting, and AEC-Q101 traceability. |
| 1.5KE15A (ON Semiconductor) | Same DO-204AC package, 15V unidirectional, but rated for 1500W peak power; higher VC = 25.5V @ 59A; non-AEC-Q101. | Over-specified for most 12V automotive use cases; lacks automotive qualification and may introduce unnecessary cost and thermal mass. | Choose 1.5KE15A only for legacy industrial designs requiring >600W headroom; P6KE15CH delivers optimal balance of AEC-Q101 compliance, 600W capability, and compact DO-15 form factor. |
Compared with SMBJ15A and 1.5KE15A, the P6KE15CH uniquely combines AEC-Q101 qualification, DO-204AC through-hole reliability, and precisely matched 22.0V clamping for 12V automotive systems-making it the preferred choice where qualification, serviceability, and voltage margin are jointly critical.

FAQ
What is the clamping voltage of P6KE15CH at its rated surge current?
The P6KE15CH has a maximum clamping voltage (VC) of 22.0 V at 28 A peak pulse current (IPP) under the standard 10/1000μs waveform. This value is measured per ANSI/IEEE C62.35 and guarantees that downstream components see no more than 22.0 V during a full-rated 600W transient event, making P6KE15CH suitable for protecting 24V-tolerant ICs on 12V rails.
Is P6KE15CH unidirectional or bidirectional, and how does that affect circuit placement?
P6KE15CH is a unidirectional TVS diode, identified by the "H" suffix denoting AEC-Q101 qualification and unidirectional construction. It must be installed with the cathode band oriented toward the protected line (e.g., 12V rail) and anode to ground. This configuration blocks reverse conduction while clamping positive transients-ideal for DC power rails where polarity is fixed and forward surge immunity (e.g., reverse battery) is also required.
Does P6KE15CH meet automotive reliability standards?
Yes, P6KE15CH is AEC-Q101 qualified, having passed stress tests including high-temperature operating life (HTOL), temperature cycling (TC), and unbiased highly accelerated stress test (UHAST). This qualification confirms suitability for automotive under-hood and cabin applications, and the "H" in P6KE15CH explicitly denotes this certified grade-distinct from non-H variants like P6KE15A.
What is the maximum steady-state power dissipation for P6KE15CH at 75°C ambient?
The steady-state power dissipation (PD) of P6KE15CH is 5 W at TA = 75°C with 9.5 mm lead lengths mounted on 5 × 5 mm copper pads. This derated value reflects thermal limits under continuous DC stress and is distinct from its 600W peak pulse rating; designers must ensure average power in clamping scenarios remains well below 5 W to avoid thermal runaway.
How does the temperature coefficient of VBR impact P6KE15CH performance in automotive environments?
P6KE15CH has a VBR temperature coefficient of 0.084 %/°C, meaning its breakdown voltage increases by ~0.011 V/°C over its –55°C to +175°C operating range. This predictable positive drift ensures clamping remains effective at high under-hood temperatures (e.g., +125°C), avoiding premature triggering or insufficient protection-critical for reliable operation in automotive power systems where ambient extremes are routine.
