Active automotive TVS with 1500 W peak pulse capacity
The 1.5KE36AHA0G: Its 30.8 V reverse standoff voltage means it sits across the supply without conducting under normal operation, then triggers at a minimum breakdown of 34.2 V and clamps to 49.9 V at the rated 31 A peak pulse current.
1500 W pulse derating and the 175 °C junction ceiling
The DO-201AA axial package (DO-27 footprint) is a through-hole format that suits point-of-entry protection on a PCB or terminal block. Power line protection is not supported — this is a unidirectional Zener-type clamp for DC rails, not AC mains.
Sourcing and compliance posture
Listed as Active on the manufacturer's status — no NRND or EOL flag. The AEC-Q101 qualification is the automotive-grade reliability standard, covering temperature cycling, ESD, and PPAP documentation.
