Housed in a DO-214AB (SMC) package, the footprint matches the industry-standard SMCJ outline — a direct drop-in for existing board layouts using that package code.","metaTitle":"1.5SMC43CAHE3/9AT TVS Diode, 1500W, 36.8V, DO-214AB","metaDescription":"Vishay 1.5SMC43CAHE3/9AT bidirectional TVS, 1500W peak pulse, 36.8V standoff, AEC-Q101 qualified.
