This unidirectional device is suited for protecting 400V nominal DC buses in automotive systems — think EV traction inverters, on-board chargers, or DC-DC converters where the bus sees load-dump or inductive kickback transients. The 1500W rating means it absorbs a single high-energy pulse without failing short, but the 2.28A peak pulse current (at 10/1000µs) sets the energy ceiling: higher surge currents call for a larger TVS or a series resistor to limit the pulse.","metaTitle":"1.5SMC480AHE3_AIH Vishay TVS, 1500W, DO-214AB, AEC-Q101","metaDescription":"Vishay 1.5SMC480AHE3_AIH Zener TVS diode, 1500W peak pulse, 408V standoff, AEC-Q101 automotive.
