This is a unidirectional device (one channel), so it protects a single rail against positive-going transients relative to ground. ## AEC-Q101 qualification and temperature range This part carries AEC-Q101 automotive qualification, meaning it has passed the stress tests (temperature cycling, high-temperature reverse bias, ESD) required for use in under-hood and chassis-mounted electronics. The TransZorb® designation is Vishay's trademark for their silicon-avalanche TVS process, which offers tighter clamping ratios and faster response times than standard Zener-based suppressors. No power line protection is claimed — this is a signal or DC rail protector, not a mains surge suppressor. The supplier device package matches the case code — DO-214AB (SMC) — so the land pattern is consistent across the series. Supplied in Tape & Reel, it is compatible with automated pick-and-place assembly.","metaTitle":"Vishay 1.5SMC220AHM3/I TVS, 1500W, 185V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC220AHM3/I Zener TVS diode, 1500W peak pulse power, 185V reverse standoff, AEC-Q101 qualified.
