The 38V gap between standoff and breakdown gives margin for normal line ripple without the TVS clipping prematurely. The 150°C TJ ceiling means the TVS can absorb repetitive pulses in a hot enclosure without derating the peak power below the 1500W headline figure, provided the average power stays within the thermal limit of the DO-214AB package. No official successor or cross-reference is listed, so the 1.5SMC400A-M3/57T is the current production variant for new builds and BOM replenishment.","metaTitle":"1.5SMC400A-M3/57T Vishay TVS, 1500W, 342V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC400A-M3/57T Zener TVS diode, 1500W peak pulse, 342V reverse standoff, 548V clamp, DO-214AB SMC package.
