The unidirectional channel (single) biases with the cathode toward the positive rail — correct orientation matters for the clamping path. ## AEC-Q101 — the automotive pedigree This part carries AEC-Q101 qualification, the automotive discrete semiconductor stress test standard. No power line protection (it is a transient suppressor, not a crowbar circuit). ## DO-214AB SMC — the board footprint Surface-mount DO-214AB (SMC) package, also known as SMCJ. The copper pad area under the cathode tab sets the thermal resistance to the board — a larger pad lowers the junction temperature rise for a given surge duty cycle.","metaTitle":"1.5SMC43AHE3/9AT Vishay TVS, 1500W, DO-214AB, AEC-Q101","metaDescription":"Vishay 1.5SMC43AHE3/9AT unidirectional Zener TVS, 1500W peak pulse, 36.8V standoff, 59.3V clamp, 25.3A Ipp. AEC-Q101 qualified.
