AEC-Q101 qualification means this part has passed the automotive-grade stress tests: high-temperature reverse bias, temperature cycling, and ESD robustness per the JEDEC standard. For an ECU or telematic control unit that must survive load-dump and inductive kickback, the AEC-Q101 lot traceability is the audit trail a component engineer needs for PPAP submission. ## Clamping voltage and surge current — the protection envelope This sets the upper bound for the voltage stress on the protected IC — a 60V-rated DC-DC converter on the same rail sees a 17V margin below its abs-max, which is comfortable for a 48V system. The bidirectional channel (single device) clamps both polarities symmetrically, so a single DO-214AB footprint protects a signal pair or a bipolar supply without needing two antiparallel unidirectional diodes. ## Active lifecycle — no end-of-life pressure Sourced per RFQ through independent and authorized distribution.","metaTitle":"Vishay 1.5SMC56CAHM3/H TVS Diode, 1500W, 77V Clamp, AEC-Q101","metaDescription":"Vishay 1.5SMC56CAHM3/H bidirectional Zener TVS, 1500W peak pulse, 77V clamp, AEC-Q101 qualified.
