The 1.5KE15A-T is a 1500 W Zener TVS diode from Diodes Incorporated, designed to clamp transient overvoltage on a 12.8 V nominal rail. The 14.3 V minimum breakdown voltage means it starts conducting just above the normal operating voltage, and the 21.2 V maximum clamping voltage at 71 A peak pulse current (10/1000 µs waveform) limits the spike the downstream circuitry sees.

Availability and pricing are confirmed at RFQ against the required quantity and date-code window. Given the EOL status, date-code provenance matters — the stock on hand is genuine, but lot-specific.
DO-201 axial package — board-fit and thermal note
Housed in a DO-201AA / DO-27 axial-lead package (through-hole), the 1.5KE15A-T mounts into a standard 0.100-inch pitch hole pattern. The Tape & Reel packaging indicates it was originally supplied for automated insertion; loose axial parts are also available through surplus channels.
