It is a unidirectional Zener-type suppressor in the DO-214AB (SMC) package. ## Automotive-grade transient protection With a 1500W peak pulse power rating at 10/1000µs, the 1.5SMC300AHM3_A/H clamps transients like load-dump and inductive kickback on 24V or 48V vehicle buses. The 414V clamping ceiling keeps the downstream circuitry below its breakdown threshold during a surge event.","metaTitle":"1.5SMC300AHM3_A/H Vishay TVS, 1.5kW, 256V Standoff","metaDescription":"Vishay 1.5SMC300AHM3_A/H automotive TVS, 1500W peak pulse, 256V standoff, AEC-Q101, DO-214AB.

The 1.5SMC300AHM3_A/H is the AEC-Q101 qualified version — the standard 1.5SMC300 (without the 'A' suffix) is electrically identical but lacks the automotive-grade screening.
