With a 13.6 V reverse standoff voltage, this TVS sits across a 12 V nominal battery line without conducting during normal operation. The 15.2 V minimum breakdown triggers clamping before the rail exceeds the downstream IC's abs-max rating. The 22.5 V clamping voltage at 66.7 A peak pulse current (10/1000 µs waveform) absorbs load-dump and inductive kickback events common in automotive and telecom power buses. The 1500 W peak pulse rating matches the 1.5SMC family's standard power envelope for this package. ## AEC-Q101 grade — what it means for underhood qualification The -65°C to 150°C junction temperature range covers underhood ambient and self-heating during a transient event. ## DO-214AB (SMC) package — board-fit note The copper pad area under the cathode tab sets the thermal resistance for pulse power dissipation; a 2-oz copper plane on the PCB improves the SOA during repetitive surges. Tape-and-reel packaging (per) supports automated pick-and-place for volume assembly. No special moisture sensitivity level is flagged — standard MSL handling applies.","metaTitle":"Vishay 1.5SMC16CAHM3/I TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC16CAHM3/I bidirectional TVS diode, 1500W peak pulse, 13.6V standoff, AEC-Q101 qualified.
