It clamps transients on a single polarity rail, shunting surge energy away from downstream circuitry before the clamped voltage reaches a damaging level. ## What the voltage ratings mean for your design The reverse standoff voltage of 70.1 V typ marks the rail the diode watches without conducting — it sits idle on a 48 V or 54 V supply without leakage loading. That 113 V clamp is the number the downstream silicon sees during a surge event — a TVS selected close to the rail standoff with a clamp well below the IC abs-max survives the transient without failing itself. This rating tells you the diode handles sustained transients without thermal runaway, which matters in AC-line-adjacent or industrial power-path applications even though this specific variant is not classified as a power-line protection device. ## Thermal and physical integration Junction temperature rating runs to 150 °C, and the operating range bottoms out at -65 °C — the diode handles cold-surge events in outdoor or vehicle-adjacent environments without the thermal margin collapsing. Tape-and-reel packaging suits automated pick-and-place on the production line.","metaTitle":"1.5SMC82A-M3/57T TVS Diode, 113V Clamping, 1.5kW","metaDescription":"Vishay 1.5SMC82A-M3/57T unidirectional TVS diode, DO-214AB SMC, 1500W peak pulse, 113V max clamping at 13.3A.
