Product details

What the 1500W rating means for your rail

The 1.5KE15CA-B: Reverse standoff voltage of 12.8V means it sits across a 12V bus without conducting in normal operation; the breakdown starts at 14.3V min, so a 12V rail with 10% tolerance stays below the trigger threshold.

Package and temperature envelope

Housed in a DO-201AA / DO-27 axial-lead through-hole package (supplier device package DO-201), the diode mounts into a standard 0.100-inch pitch hole pattern — no reflow profile needed, just a wave or hand-solder step.

Frequently asked questions

What is the closest pin-compatible alternative to 1.5KE15CA-B in this Circuit Protection family?

No official successor or pin-compatible cross-reference is recorded from the manufacturer. The 1.5KE series includes many bidirectional 1500W parts at different standoff voltages, but a direct replacement would require matching the 12.8V standoff, 14.3V breakdown, and 21.2V clamp — a board spin may be needed if the original part is unavailable.
