Product details
Overview
P6KE15CA from Taiwan Semiconductor is a bidirectional 600W transient voltage suppressor (TVS) diode designed for robust overvoltage protection in power and signal lines. It features a nominal breakdown voltage of 15 V, clamps transients to ≤22.0 V at 28.0 A peak surge current, and operates with low dynamic impedance and sub-nanosecond response time - ideal for automotive ECU input protection against ISO 7637-2 pulses.
For engineers reviewing the P6KE15CA datasheet, P6KE15CA pinout, P6KE15CA application, or P6KE15CA equivalent, key selection criteria include its bidirectional DO-15 package, 12.1 V stand-off voltage, <1 μA leakage at 12.1 V, ±175°C junction rating, and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
The P6KE15CA is a silicon avalanche diode configured as a bidirectional TVS, enabling symmetrical clamping in both polarities without external polarity management. Its 10/1000 μs surge rating of 600 W and clamping voltage of 22.0 V at 28.0 A define its energy-handling capability under standardized lightning and switching transient waveforms.
It exhibits a temperature coefficient of VBR of 0.084 %/°C and maintains stable performance across –55 °C to +175 °C operating range. The device uses a single-die DO-204AC (DO-15) package with pure tin-plated leads compliant with J-STD-002 solderability and JESD201 Class 2 whisker resistance.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar transient voltage suppression applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SMBJ15CA (Bourns) | Same 15 V nominal, 600 W rating, but SMB package (surface-mount); lower thermal resistance than DO-15. | Preferred for space-constrained PCBs; requires reflow-compatible layout and lacks axial lead mechanical robustness. | Select when board area is limited and automated assembly is used; verify thermal pad design for sustained surge duty. |
| 1.5KE15CA (ON Semiconductor) | Identical DO-15 package and electrical specs (15 V, 600 W, bidirectional); minor VBR tolerance difference (13.5–16.5 V vs. 13.7–16.3 V). | Drop-in replacement in legacy designs; same footprint, lead form, and AEC-Q101 qualification status. | Choose for second-source assurance where Taiwan Semiconductor supply continuity is constrained; no layout or test changes needed. |
Compared with SMBJ15CA and 1.5KE15CA, the P6KE15CA offers identical protection performance in a through-hole DO-15 package optimized for manual assembly, high-vibration environments, and legacy automotive harness interfaces - making it preferred where mechanical reliability and serviceability outweigh miniaturization needs.

FAQ
What is the clamping voltage of P6KE15CA and how is it measured?
The P6KE15CA has a maximum clamping voltage (VC) of 22.0 V at a peak pulse current (IPP) of 28.0 A, tested using the standardized 10/1000 μs double-exponential surge waveform. This value represents the highest voltage the device allows across its terminals during a transient event, directly protecting downstream components from overvoltage stress. The specification is guaranteed across the full operating temperature range and forms the basis for safe margining in circuit design.
Is P6KE15CA suitable for automotive applications?
Yes, P6KE15CA is AEC-Q101 qualified and explicitly rated for automotive use. Its –55 °C to +175 °C operating junction temperature range, robust surge handling (600 W at 10/1000 μs), and DO-15 mechanical construction meet requirements for engine bay, chassis, and body electronics. Taiwan Semiconductor's documentation confirms qualification for load dump, jump start, and ISO 7637-2 pulse testing - making P6KE15CA a validated choice for automotive power rail protection.
How does P6KE15CA differ from the unidirectional P6KE15A?
P6KE15CA is bidirectional, providing symmetrical clamping for both positive and negative transients, while P6KE15A is unidirectional and requires correct polarity orientation during placement. The CA suffix denotes bidirectional functionality, eliminating need for polarity-aware routing. Electrically, P6KE15CA has identical VBR (13.5–16.5 V), VC (22.0 V), and PPK (600 W) ratings as P6KE15A, but differs in leakage behavior and application flexibility - especially critical in AC-coupled or floating systems.
What is the maximum steady-state power dissipation for P6KE15CA?
The P6KE15CA has a steady-state power dissipation (PD) of 5 W at TA = 75 °C with 9.5 mm lead lengths mounted on 5 × 5 mm copper pads. This rating applies only to continuous DC or low-frequency reverse-bias conditions - not transient surges. In normal operation, leakage current remains below 1 μA at 12.1 V, resulting in negligible static power loss. The 5 W rating supports thermal design margins during abnormal fault conditions or elevated ambient temperatures.
Does P6KE15CA have UL recognition and RoHS compliance?
Yes, P6KE15CA carries UL Recognition under File #E-326243 and is fully RoHS compliant and halogen-free per IEC 61249-2-21. These certifications are documented in Taiwan Semiconductor's official P6KE series datasheet (Version P2203) and verified on authorized distributor listings. UL recognition validates safety for end-product certification in North America, while RoHS/halogen-free status ensures compliance with global environmental directives for industrial and automotive manufacturing.
