Product details
Overview
P6KE11CA from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in DC power rails and signal lines. It features a nominal breakdown voltage of 11 V, clamps transients to ≤16.2 V at 38 A peak surge current (10/1000 µs), and operates with <1 µA reverse leakage at its 8.92 V stand-off voltage. It is commonly deployed in automotive body control modules and industrial I/O interfaces requiring AEC-Q101-qualified surge immunity.
For engineers reviewing the P6KE11CA datasheet, P6KE11CA pinout, P6KE11CA application, or P6KE11CA equivalent, key selection criteria include its bidirectional configuration, DO-204AC (DO-15) package compatibility, 175°C maximum junction temperature, and compliance with IEC 61000-4-2/4-4/4-5 ESD/EFT/surge immunity standards.
Technical Context
The P6KE11CA implements a silicon avalanche diode structure optimized for fast clamping response - typically under 5.0 ns from 0 V to VBR in bidirectional mode. Its low dynamic impedance ensures minimal voltage overshoot during high-current transients, while its 10/1000 µs waveform-rated 600 W peak pulse power supports repetitive surge events up to 4 pulses per minute at 25°C ambient.
Thermal derating follows a linear curve above 25°C, maintaining 5 W steady-state dissipation at 75°C with 9.5 mm lead lengths on 5×5 mm copper pads. The device's ±0.075 %/°C VBR temperature coefficient enables stable clamping across -55°C to +175°C operating range without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Pulse Power (10/1000 µs) | 600 W - sustains single high-energy surges common in ISO 7637-2 Load Dump and IEC 61000-4-5 Level 4 testing |
| Breakdown Voltage VBR | 9.90–12.1 V @ 1 mA - defines precise avalanche initiation threshold for reliable overvoltage triggering |
| Stand-Off Voltage VWM | 8.92 V - maximum continuous DC or RMS voltage the device blocks without conduction |
| Clamping Voltage VC | ≤16.2 V @ 38 A - limits downstream circuit voltage during worst-case surge, protecting 12 V logic and analog ICs |
| Reverse Leakage ID | <1 µA @ 8.92 V - negligible standby power loss and no measurable loading on protected signal/power lines |
| Junction Temperature Range | -55°C to +175°C - supports under-hood automotive, industrial motor drives, and outdoor power supply applications |
| Package | DO-204AC (DO-15) - industry-standard axial-leaded package with tin-plated leads compliant to J-STD-002 solderability |
Pinout & Package
DO-204AC (DO-15) axial-leaded package with cathode band marking for polarity identification. Bidirectional operation means both terminals are functionally symmetric; no anode/cathode distinction applies in circuit use.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode / Cathode (symmetrical) | Bidirectional avalanche junction | Either terminal serves as input/output for transient energy; no directional bias required in PCB layout |
| Leads (both) | Thermal and electrical interface | Provide mechanical mounting, heat conduction to PCB copper, and low-inductance path for surge current return |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS sensor interfaces |
| Fast 5.0 ns response time | Clamps transients before sensitive ICs experience damaging overvoltage stress |
| UL 94V-0 molded compound | Self-extinguishing encapsulation meets flame-retardant safety requirements for enclosed systems |
| Halogen-free per IEC 61249-2-21 | Complies with environmental regulations for RoHS-compliant manufacturing and end-of-life disposal |
| Low dynamic impedance | Minimizes clamping voltage rise under high di/dt conditions, improving protection margin |
Applications
| Automotive Body Control Module | Industrial PLC Digital Input |
|---|---|
|
Use Scenario: Protecting microcontroller GPIOs and CAN transceiver power rails from load dump and jump-start surges. IC Role / Device Role: Primary overvoltage clamp on 12 V supply line upstream of LDO regulators.

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ11CA (Bourns) | Same 11 V nominal, 600 W rating, but SMB package (surface-mount); lower thermal resistance (35°C/W vs. 50°C/W) | Requires PCB rework for SMT assembly; unsuitable for through-hole legacy designs | Select when board space is constrained and automated assembly is used. |
| 1.5KE11CA (ON Semiconductor) | Identical DO-204AC package and 11 V rating, but rated for 1500 W peak power (10/1000 µs); higher clamping voltage (17.5 V) | Over-spec for most 12 V systems; may allow excessive voltage stress on downstream 15 V-tolerant ICs | Choose only where legacy 1.5KE footprint reuse is mandatory and 17.5 V clamping is acceptable. |
Compared with SMBJ11CA and 1.5KE11CA, the P6KE11CA offers optimal balance of through-hole manufacturability, 16.2 V clamping headroom for 12 V systems, and AEC-Q101 qualification - making it the preferred choice for new automotive and industrial designs requiring proven reliability in axial-leaded form.

FAQ
What does the 'CA' suffix indicate in P6KE11CA?
The 'CA' suffix in P6KE11CA denotes a bidirectional configuration - meaning the device functions identically in both polarities and has no designated anode or cathode. This allows it to protect AC-coupled signals or dual-polarity DC rails without orientation constraints during PCB placement. Unlike unidirectional variants (e.g., P6KE11A), the P6KE11CA provides symmetrical clamping behavior essential for RS-485, CAN, and other balanced interfaces.
Is P6KE11CA AEC-Q101 qualified?
Yes, P6KE11CA is AEC-Q101 qualified per the manufacturer's ordering code documentation - specifically indicated by the 'H' suffix variant (e.g., P6KE11CAH). While the base P6KE11CA part number itself is not automatically qualified, Taiwan Semiconductor explicitly lists P6KE11CAH as AEC-Q101 compliant in its ordering information, confirming suitability for automotive applications including under-hood ECUs and body electronics where reliability under thermal and mechanical stress is critical.
What is the maximum clamping voltage of P6KE11CA at rated surge current?
The maximum clamping voltage (VC) of P6KE11CA is 16.2 V at 38 A peak pulse current (IPP) under the standard 10/1000 µs waveform. This value is guaranteed across the full operating temperature range and represents the upper limit of voltage seen by protected circuitry during worst-case surge events - a key parameter for ensuring compatibility with 12 V system components rated for ≤16.5 V absolute maximum input.
Can P6KE11CA be used in place of P6KE11A?
No, P6KE11CA cannot directly replace P6KE11A without circuit review: P6KE11A is unidirectional (anode/cathode marked), while P6KE11CA is bidirectional (no polarity marking). Substituting them risks incorrect biasing in DC-only applications and may compromise protection in AC or floating-ground scenarios. Layout changes and functional verification are required if swapping between these configurations - they are not pin-compatible alternatives.
What is the thermal resistance (RθJA) of P6KE11CA in DO-204AC package?
Taiwan Semiconductor specifies a junction-to-ambient thermal resistance (RθJA) of 50°C/W for the P6KE11CA in DO-204AC (DO-15) package, measured with 9.5 mm lead lengths mounted on 5×5 mm copper pads. This value assumes natural convection cooling and defines the temperature rise per watt of steady-state power dissipation - critical for calculating safe operating area during repetitive surge events or elevated ambient conditions.
