At 114 V minimum breakdown, it starts conducting; the 165 V clamp at 9.1 A sets the maximum voltage the protected load sees during a surge. Power line protection is not specified — this is a signal- or DC-rail TVS, not an AC mains suppressor. ## Active production, sourced per RFQ Listed as Active by Vishay.","metaTitle":"1.5SMC120A-M3/9AT Vishay TVS, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC120A-M3/9AT Zener TVS diode, 1500W peak pulse, 102V standoff, 165V clamp.
