The 70.1V clamp ensures downstream components rated for 75V or higher see a safe voltage during a surge event. The supplier device package is listed as DO-214AB (SMCJ), which is the standard JEDEC outline for this power level. The device does not include power line protection features — it is a general-purpose transient suppressor for signal or low-power DC buses.","metaTitle":"Littelfuse 1.5SMC51A TVS Diode, 1.5kW, 70.1V Clamp","metaDescription":"Littelfuse 1.5SMC51A Zener TVS, 1500W peak pulse, 70.1V clamping, 43.6V standoff.
