No stock-holding claim; availability verified per inquiry. ## 1500W peak pulse — what the rating means for protection At 2.28A peak pulse current, the device clamps at 658V max. For a 400V nominal DC bus, this provides margin for transients without interfering with normal operation. ## DO-214AB SMC — surface-mount board fit This is a standard surface-mount TVS package, compatible with reflow soldering. Single unidirectional channel — intended for DC rail protection where polarity is fixed. No power line protection, meaning it is not rated for AC mains surge suppression; it is a secondary-side transient clamp for sensitive electronics.","metaTitle":"1.5SMC480A-E3/57T Vishay TVS, 1500W, 408V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC480A-E3/57T TransZorb TVS, 1500W peak pulse, 408V reverse standoff, 658V clamp.
