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. ## Sourcing posture for this active part Listed as active in production.","metaTitle":"1.5KE20AHA0G TVS Diode, 1500W, 17.1V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE20AHA0G Zener TVS, 1500W peak pulse, 17.1V reverse standoff, AEC-Q101 qualified.
