The TransZorb® construction delivers low clamping factor and fast response to transients, which is critical for protecting sensitive ECU, sensor, and infotainment bus lines from load-dump and inductive kickback events. ## Package and board-fit considerations The copper pad area under the cathode tab sets the thermal resistance — for the full 1500 W pulse, the PCB copper area should follow the Vishay application note derating curve.","metaTitle":"Vishay 1.5SMC39AHM3/H Zener TVS, 1.5kW, DO-214AB","metaDescription":"Vishay 1.5SMC39AHM3/H Zener TVS diode, 1500W peak pulse, 33.3V standoff, AEC-Q101 qualified.
