The breakdown threshold of 8.65 V minimum is where the device begins to conduct, which is where the clamping action starts. This 7.78 V standoff / 13.4 V clamping window targets 12 V automotive rails where load-dump transients can spike well above the supply rail — the TVS clamps the overvoltage before the protected ECU input sees it. ## AEC-Q101 grade and automotive deployment Junction temperature rating is -65 to 150 °C, which covers the under-hood ambient band with margin — an ECU in a sealed engine bay that hits 125 °C still has 25 °C of Tj headroom before the TVS derates. ## DO-214AB package and board assembly Tape & Reel packaging is the default for high-volume assembly; the part mates with standard SMT pick-and-place tooling at the DO-214AB package height.","metaTitle":"Vishay 1.5SMC9.1CAHE3/57T TVS Diode, 1500W, 7.78V","metaDescription":"AEC-Q101 qualified bidirectional TVS Zener in DO-214AB. 7.78V standoff, 8.65V breakdown, 13.4V clamping at 112A peak pulse.
