The margin between the rail voltage and the clamp determines how much overvoltage the downstream circuitry must survive. Because this is a Zener-type TVS (not a punch-through or MOV), the clamping voltage is sharper and the leakage current at standoff is lower than an equivalent varistor — relevant for always-on automotive modules where quiescent draw matters. ## Active lifecycle — no LTB urgency, but confirm date codes That said, the 1.5SMC series has been in the market for years. If you are sourcing through independent channels, verify the date code against the manufacturer's last PCN to ensure the parts are not stale inventory approaching the solderability window for the DO-214AB termination finish.","metaTitle":"1.5SMC47AHM6G TVS Diode, 1500W, DO-214AB, AEC-Q101","metaDescription":"Taiwan Semiconductor 1.5SMC47AHM6G Zener TVS, 1500W peak pulse, 64.8V clamping, AEC-Q101 automotive grade.
