The unidirectional clamping action (single channel) means the cathode band on the DO-214AB package must face the positive rail. ## AEC-Q101 qualification and -65 to 150 °C operating range This part carries AEC-Q101 automotive qualification, meaning it has passed the stress tests (temperature cycling, high-temperature reverse bias, humidity, and ESD) required for under-hood and cabin electronics. The junction temperature range of -65°C to 150°C covers cold-crank and under-hood heat soak. ## Package and board-fit for DO-214AB (SMC) The supplier device package is listed as DO-214AB (SMCJ), which is the same mechanical outline. The copper pad area under the cathode tab on the PCB sets the thermal resistance — a larger pad improves heat sinking during repetitive surge events. The part ships on tape and reel (TR), compatible with standard pick-and-place assembly.","metaTitle":"Vishay 1.5SMC47AHE3/57T TVS, 1500W, DO-214AB","metaDescription":"Active Vishay 1.5SMC47AHE3/57T Zener TVS, 1500W peak pulse, 40.2V standoff, 64.8V clamp.
