The operating junction temperature range spans -65°C to 150°C, so it survives cold-crank dips and under-hood heat soak without derating the peak pulse power. ## Where it fits — automotive and telecom transient protection Listed for Automotive and Telecom applications, this unidirectional Zener TVS is suited for clamping positive transients on DC power rails, signal lines, and low-voltage bus interfaces in engine control units, infotainment, telematics, and base-station power supplies. The 1.5SMC series is a standard 1500 W platform with a wide breakdown voltage range; the '18' in the base number 1.5SMC18 identifies the 15.3 V standoff variant, which is a common choice for protecting 12 V battery-fed circuits against load-dump and inductive kickback.","metaTitle":"Vishay 1.5SMC18AHM3/H TVS, 1500W, DO-214AB, AEC-Q101","metaDescription":"Active Vishay 1.5SMC18AHM3/H Zener TVS, 1500W peak pulse, 15.3V standoff, AEC-Q101 automotive grade.
