No power line protection rating is assigned, confirming this is a signal- or low-power-rail TVS rather than an AC mains protector.","metaTitle":"Vishay 1.5SMC12A-E3/57T TVS Diode, 1500W, DO-214AB","metaDescription":"Vishay 1.5SMC12A-E3/57T Zener TVS diode, 1500W peak pulse power, 10.2V standoff, DO-214AB SMC.
