The reverse standoff voltage is 185 V, meaning the diode stays off below that DC level and only starts conducting when the line voltage exceeds the breakdown threshold of 209 V min. This makes it a fit for 185 V nominal rails — think industrial DC buses or telecom supplies — where the TVS sits across the line and shunts transients without loading the rail during normal operation. The product status is Active per Vishay's lifecycle record — no phase-out or last-time-buy notice on file.","metaTitle":"1.5SMC220A-E3/57T Vishay TVS, 1500W, 185V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC220A-E3/57T Zener TVS, 1500W peak pulse, 185V reverse standoff, 328V clamp.
