AEC-Q101 qualification confirms the device meets automotive-grade reliability screening — junction temperature range of -65°C to 150°C covers under-hood and cabin environments. The single unidirectional channel is polarity-specific; the cathode band on the DO-214AB (SMC) package must align with the protected rail. ## Clamping performance and board-level integration The 64.8 V clamping ceiling keeps the voltage stress on downstream FETs and ICs within their BVdss and V(BR) ratings for a 48 V bus. Surface-mount DO-214AB (SMC) footprint — the same pad layout as standard SMC diodes. The 1500 W rating assumes a copper pad area matching the datasheet's recommended pattern; smaller pads increase thermal resistance and reduce the effective pulse-handling margin. No power line protection means this is a signal/transient clamp, not a mains surge protector.","metaTitle":"Vishay 1.5SMC47AHM3_A/I TVS, 1500W, 40.2V, DO-214AB","metaDescription":"Vishay 1.5SMC47AHM3_A/I Zener TVS diode, 1500W peak pulse, 40.2V reverse standoff, DO-214AB SMC, AEC-Q101 qualified.
