The reverse standoff voltage of 376V means the protected line should never exceed this during normal operation; above that the diode starts conducting leakage current. The clamping voltage of 602V at 2.5A is the voltage the downstream circuit sees during the surge — make sure your load's abs-max rating sits above 602V. ## Package and rework — DO-214AB (SMC) in the field It's a standard two-pad outline — no exposed paddle, no thermal pad to worry about. On a rework station with hot air, you can swap it in under a minute; the body is large enough to grip with tweezers, and the polarity band is clearly marked on the top.","metaTitle":"1.5SMC440A-M3/57T TVS Diode, 1500W, 602V Clamp, DO-214AB","metaDescription":"Vishay 1.5SMC440A-M3/57T Zener TVS, 1500W peak pulse, 376V standoff, 602V clamp.
