For a 24 V automotive system with a 28 V nominal alternator output, this provides margin before the TVS begins to avalanche. ## Package, mounting, and assembly integration Housed in the standard DO-214AB (SMC) surface-mount package, the part mates with the JEDEC footprint for this outline. The DO-214AB body is larger than the DO-214AA (SMA) sibling, which allows the 1500 W dissipation without exceeding the package thermal limits. ## Active lifecycle — sourcing posture for this part Production status is active per the manufacturer. There is no indication of NRND or EOL notice.","metaTitle":"Vishay 1.5SMC33CAHM3/I TVS, 1500W, 28.2V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC33CAHM3/I bidirectional TVS, AEC-Q101 qualified, 1500W peak pulse, 28.2V standoff, DO-214AB.
