That 1500 W rating means it can absorb a single 10/1000 µs surge up to that power level without failing short — the scorch mark tells you if the energy exceeded the part's capability. For a 24 V or 48 V automotive bus, this device sits on the higher-voltage side, typically used on the secondary side of an isolated DC-DC or on a 120 V nominal intermediate bus. ## Package and board-fit: DO-214AB (SMC) Housed in the DO-214AB (SMC) package, the same footprint as the SMCJ suffix. Surface-mount, with the cathode band marking the orientation for unidirectional parts — but this is a bidirectional channel, so polarity does not matter. The package sits low-profile on the board, and the copper pad area under the tab sets the thermal resistance for repetitive pulse handling. Operating junction temperature range is -65°C to +150°C, covering the full automotive under-hood and cabin ambient.","metaTitle":"Vishay 1.5SMC150CAHE3/9AT TVS, 1500W, DO-214AB","metaDescription":"1.5SMC150CAHE3/9AT 1500W bidirectional TVS diode, AEC-Q101 qualified, 128V standoff, 207V clamp.
