The DO-214AB (SMC) surface-mount package suits reflow assembly and keeps the thermal path short to the PCB copper for heat spreading. ## Clamping voltage and standoff margin The 190 V minimum breakdown voltage (VBR) provides a 19 V guard band above the rail — enough to ride through normal line ripple without nuisance triggering. That 274 V is the hard limit the protected circuit sees; the designer sizes the downstream capacitor voltage rating and the DC-DC converter input range against this ceiling. Operating temperature spans -65°C to 150°C junction, covering cold-start automotive and hot industrial cabinet environments. Power derating above 25°C follows the standard exponential curve — at 150°C the device handles roughly 20% of the 1500 W rating.","metaTitle":"Vishay 1.5SMC200A-M3/57T TVS, 1500W, 274V Clamp, DO-214AB","metaDescription":"Vishay 1.5SMC200A-M3/57T Zener TVS diode, 1500W peak pulse, 171V standoff, 274V clamp.
