Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE43CAHA0G mounts through-hole and is supplied in Tape & Box format. The DO-201 footprint is standard across the 1.5KE family, so the pad layout and lead spacing are consistent with other 1500 W TVS diodes in this package. For reflow assembly, the axial leads require a wave-solder or hand-solder process — this part is not intended for surface-mount reflow ovens.
Yes, the 1.5KE43CAHA0G carries AEC-Q101 qualification, making it suitable for automotive-grade applications requiring controlled reliability and stress screening.
