The 13A peak pulse current rating at that clamping voltage tells you the surge the part can absorb before the junction temperature runs away. The reverse standoff voltage is 66.4V — this is the maximum DC or peak-AC voltage the TVS can sit across without conducting appreciably. Above that, breakdown starts at a minimum of 73.8V. The DO-201AA axial package (DO-27 equivalent) is through-hole, which means the leads carry the heat into the PCB copper; a 2oz copper pour on each side of the mounting hole improves the thermal impedance for repetitive surge events.","metaTitle":"1.5KE82H Taiwan Semiconductor Zener TVS, 1500W, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE82H automotive-grade Zener TVS diode, 1500W peak pulse power, 66.4V standoff, DO-201 axial.
