Product details

The 1.5KE30CAHE3/51: Reverse standoff voltage is 25.6 V, meaning the diode draws negligible leakage below that rail; breakdown triggers at a minimum of 28.5 V, so a 24 V automotive bus stays within the safe window.

Automotive grade and package fit

Through-hole DO-201AA (DO-27) axial package — the same footprint as the standard 1.5KE series, so a board already laid out for a 1.5KE30CA accepts this variant without a layout change.

Frequently asked questions

What does the AEC-Q101 rating mean for this TVS?

AEC-Q101 is the automotive discrete semiconductor qualification standard. It certifies the part for -55°C to 175°C operation, reliability stress testing, and PPAP documentation — required for Tier-1 automotive ECU builds.
