The 58.1 V reverse standoff Typ places the working rail just below the minimum breakdown of 64.6 V; any overvoltage event exceeding that threshold causes the Zener channel to avalanche and clamp, routing the surge current to ground before the protected node sees damage. ## Automotive temperature and qualification grade Surface-mount DO-214AB is the standard SMC package for this series; the foot pattern lands on the board with the same thermal pad practice as other SMC-bodied TVS parts in the same family, so a replacement pin-compatible part in the same series shares the same pad layout. ## Sourcing and availability Vishay lists the 1.5SMC68AHE3/57T as Active; it carries the full series base number 1.5SMC68, confirming it sits within an active family with continued automotive production support. Sourced through independent distribution and quoted to order — availability and lead time confirmed at RFQ against your BOM quantity.","metaTitle":"Vishay 1.5SMC68AHE3/57T TVS Diode, 1500W, 58.1V","metaDescription":"Vishay 1.5SMC68AHE3/57T automotive Zener TVS diode, 1500W peak pulse, 58.1V standoff.
