Product details

Peak pulse power and clamping for 12V/24V automotive rails

The 1.5KE20AHA0G is a 1500W peak pulse power Zener TVS diode in the 1.5KE series from Taiwan Semiconductor. Its 17.1V reverse standoff voltage and 27.7V maximum clamping at 56A (10/1000µs waveform) make it a fit for protecting 12V and 24V automotive power rails against load-dump and inductive kickback transients.

AEC-Q101 qualification and temperature envelope

The qualification covers the reliability stress and PPAP requirements that procurement teams need for automotive BOMs.

Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE20AHA0G mounts through-hole. The DO-201 footprint is a standard across the 1.5KE series, so a single PCB layout serves the full voltage range from 6.8V to 440V standoff.
