The 77.8V standoff rating defines the working voltage the circuit runs at continuously without the TVS conducting — the gap between 77.8V and 125V is the protection headroom. Junction temperature rating extends to 150°C, which gives margin in enclosed or thermally challenging environments. The -65°C low end covers cold-start and outdoor equipment — the die doesn't see damage at cold extreme the way some lower-rated parts do.","metaTitle":"Vishay 1.5SMC91CA-M3/9AT TVS Diode, 125V Clamping","metaDescription":"Vishay 1.5SMC91CA-M3/9AT bidirectional Zener TVS, 77.8V standoff, 125V clamping, 1.5kW peak pulse, DO-214AB SMC.
