Product details

The 1.5KE180AHA0G: The 1500W peak pulse rating (10/1000µs waveform) is the energy-handling capacity per event — for a 24V automotive system, this absorbs the surge from an alternator load-dump without the TVS failing short.

Package and board-fit — DO-201 axial through-hole

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE180AHA0G mounts through-hole — the leads are formed for axial insertion, and the body is suited for point-to-point wiring or PCB mounting with adequate copper pad area for heat sinking during the pulse.
