Housed in the DO-214AB (SMC) package, also referred to as SMCJ, this is a surface-mount package with a standard footprint. The wide copper tab on the bottom side carries the heat to the PCB copper plane — the 1500 W rating assumes a good thermal connection to the board, so the layout should include a solid pad and thermal vias under the package.","metaTitle":"Vishay 1.5SMC120CAHE3/9AT TVS, 1500W, Bidirectional","metaDescription":"Vishay 1.5SMC120CAHE3/9AT Zener TVS diode, 1500W peak pulse, 102V standoff, bidirectional, AEC-Q101, DO-214AB.

A direct pin-compatible alternative would be another 1.5SMC series part in the same DO-214AB package with the same standoff voltage — for example, the unidirectional 1.5SMC120AHE3/9AT. Confirm the polarity (bidirectional vs unidirectional) before substituting."},{"question":"What compliance documentation does Vishay provide for 1.5SMC120CAHE3/9AT?","answer":"As an AEC-Q101 qualified part, it comes with automotive-grade PPAP documentation upon request.
