The AEC-Q101 qualification certifies this part for automotive-grade reliability — temperature cycling, high-temperature reverse bias, and ESD robustness per the standard. The wide-body SMC package handles the 1500W pulse without exceeding the junction temperature limit — the copper pad area under the cathode tab sets the thermal resistance to the board.","metaTitle":"1.5SMC22AHM3/I Vishay TVS, 1500W, 18.8V Standoff, DO-214AB","metaDescription":"Vishay 1.5SMC22AHM3/I automotive TVS diode, 1500W peak pulse, 18.8V reverse standoff, AEC-Q101 qualified.
