That clamp voltage tells you the downstream silicon must survive at least 64.5 V for the duration of the surge — a 60 V-rated MOSFET or 63 V capacitor is marginal here; 75 V or 100 V parts give proper margin. ## Package, temperature, and board-fit The SMC footprint is larger than the smaller SMA/SMB packages, which helps spread the transient heat into the PCB copper — important for repetitive surge events where the junction temperature accumulates. No power line protection feature is claimed — this is a signal- or low-power-rail TVS, not a mains-grade protector.","metaTitle":"SMCJ40A-13 TVS Diode, 1500W, 40V Standoff, DO-214AB","metaDescription":"Diodes Inc SMCJ40A-13 Zener TVS, 1500W peak pulse, 40V reverse standoff, 64.5V clamp, DO-214AB.
