With a clamping voltage of 165 V at 9.5 A peak pulse current, the device limits the transient to a level that a 150 V-rated MOSFET or controller can survive, provided the PCB trace inductance and TVS placement keep the loop tight. ## Package and board integration The DO-214AB footprint is standard for 1500 W TVS diodes — the copper pad area under the cathode tab directly sets the thermal resistance to ambient, so the PCB layout must allocate enough copper to dissipate the pulse energy without exceeding the 150°C junction limit.","metaTitle":"1.5SMC120AHR7G TVS, 1500W, 102V Standoff, DO-214AB","metaDescription":"Taiwan Semiconductor 1.5SMC120AHR7G Zener TVS, 1500W peak pulse, 102V standoff, AEC-Q101 automotive grade.
