Its 171V reverse standoff voltage sits below the 190V minimum breakdown threshold, meaning a 170V DC bus or a 120V AC rectified rail (with headroom for nominal tolerance) stays within the safe operating region until a transient pushes the voltage past the avalanche point. ## Package and board-fit — DO-214AB (SMC) footprint The DO-214AB (SMC) surface-mount package is the same footprint used across the 1.5SMC family, so a board already laid out for a 1500W SMC TVS accepts this part without a pad revision. The single bidirectional channel means one device protects both polarities on a signal or power rail — no need to pair two unidirectional parts back-to-back. Operating junction temperature spans -65°C to 150°C, covering the full automotive ambient range plus self-heating margin during a pulse.","metaTitle":"1.5SMC200CAHM3/H TVS Diode, 1500W, 274V Clamp, DO-214AB","metaDescription":"Vishay 1.5SMC200CAHM3/H bidirectional TVS, AEC-Q101, 1500W peak pulse, 171V standoff, DO-214AB.
