For a 48 V nominal line (common in industrial 24-60 V power rails), 58.1 V standoff gives reasonable headroom above the steady-state peak. The 92 V clamping ceiling needs to sit below the absolute-max rating of whatever downstream IC or MOSFET it is protecting — if the downstream device can't take 92 V under a surge, the TVS won't save it. ## Thermal and mounting notes The junction temperature rating is -65°C to 150°C (TJ). The DO-214AB package thermal resistance to the board pad matters more than the headline junction rating — the clamping energy rating (1.5 kW) assumes the recommended pad geometry in the datasheet. Skimp on the solder pad and the part unclamps early under a real surge. Tape & Reel packaging suits automated SMT placement. The 1.5SMC68A base product number means the die and construction are consistent across the series — stepping up or down within the family (different standoff voltages) keeps the same footprint. Vishay lists this part as Active.","metaTitle":"Vishay 1.5SMC68A-M3/57T Zener TVS Diode, 1500W Peak","metaDescription":"Vishay 1.5SMC68A-M3/57T unidirectional Zener TVS in DO-214AB (SMC). 58.1V standoff, 92V clamping, 1500W peak pulse.
