The 19 V minimum breakdown voltage ensures the diode stays off the line during normal operation while triggering before the downstream silicon sees damaging overvoltage. Operating junction temperature spans -65°C to 150°C, covering the under-hood and engine-bay thermal profile where ambient can reach 125°C with self-heating margin. The DO-214AB (SMC) surface-mount package mates with standard reflow profiles and provides the copper pad area needed to sink pulse heat into the PCB. Listed applications include Automotive and Telecom — the single unidirectional channel protects a single rail or signal line. The part carries no power line protection, meaning it is intended for DC power buses or low-impedance signal lines rather than AC mains.","metaTitle":"Vishay 1.5SMC20AHM3_A/H TVS Diode, AEC-Q101, 1500W","metaDescription":"Vishay 1.5SMC20AHM3_A/H Zener TVS, 1500W peak pulse, 17.1V standoff, AEC-Q101 qualified.
