Breakdown starts at 20.9 V minimum, and the clamping voltage is held to 30.6 V at 49 A peak pulse current. For a 24 V truck system, that clamp keeps the downstream electronics within a 36 V absolute-max rating typical of many ECUs and sensors. The SMC footprint is larger than the SMA/SMB siblings, offering better thermal dissipation for the 1500 W pulse — the copper pad area under the cathode tab should follow the Vishay application note for optimal RthJA.","metaTitle":"Vishay 1.5SMC22CAHE3/9AT TVS, 1.5kW, 18.8V, DO-214AB","metaDescription":"Vishay 1.5SMC22CAHE3/9AT bidirectional TVS diode, 1500W peak pulse, 18.8V standoff, AEC-Q101 qualified.
