Product details

The P6KE12CA-T: The clamping voltage at that peak current is 16.7V max, so a 12V rail sees the spike held under 17V. Reverse standoff voltage is 10.2V typical — the TVS draws negligible leakage below this level, making it suitable for protecting 12V nominal supply lines. Breakdown voltage starts at 11.4V min, ensuring the device does not conduct during normal operation.

Package and deployment context

Through-hole mounting suits point-to-point wiring or prototype boards where rework access is needed. No power line protection (internal construction is not designed for continuous overvoltage) — intended for transient suppression only, not as a shunt regulator.

Frequently asked questions

Where can I buy the P6KE12CA-T?

The P6KE12CA-T is obsolete but available through independent surplus channels.

What is the closest pin-compatible alternative to the P6KE12CA-T?

No official pin-compatible successor is listed by Diodes Incorporated for this part. For a functional equivalent, a TVS with the same package (DO-15), 600W rating, and 10.2V standoff in a bidirectional configuration would be the closest parametric match — confirm the breakdown and clamping voltages against the BOM requirement.
