The 165V clamp ceiling means downstream components rated for 200V or higher see a safe voltage during a surge event. ## Package and board integration Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE120A B0G is a through-hole device intended for point-to-point wiring or PCB mounting with lead forming. The DO-201 body handles the thermal pulse of a 1500W surge without requiring a heatsink, relying on the lead-frame and solder joints to conduct heat into the board copper. The wide range also supports applications that see cold starts or high-temperature soak-back. The bulk packaging suits high-volume assembly or bench stock for repair and prototyping.","metaTitle":"1.5KE120A B0G TVS Diode, 1500W, 102V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE120A B0G Zener TVS, 1500W peak pulse power, 102V reverse standoff, 165V clamp.
