Surface-mount DO-214AB (SMC) package with a standard footprint — the same pad pattern used across the 1.5SMC family, so a BOM change to a different standoff voltage requires no board layout revision.","metaTitle":"1.5SMC30CAHM3/I TVS Diode, 1.5kW, AEC-Q101, DO-214AB","metaDescription":"Vishay 1.5SMC30CAHM3/I bidirectional TVS, 1.5kW peak pulse, 25.6V standoff, AEC-Q101 qualified.
