The breakdown voltage range starts at 11.4 V minimum, ensuring the device remains non-conductive below the rail voltage and triggers only when a transient pushes the line above that threshold. ## Through-hole DO-201 axial — board-fit note Housed in a DO-201AA (DO-27) axial-lead package, the part is supplied in bulk and mounts through-hole. The DO-201 footprint is common across the 1.5KE family, so a single PCB layout accepts the full voltage range from 6.8 V to 440 V standoff variants. The axial leads carry the surge current into the copper pad area — keep the trace width to the pad at least equivalent to the lead diameter to avoid a fuse effect under peak pulse.","metaTitle":"1.5KE12A B0G TVS Zener, 1500W, DO-201, Active","metaDescription":"Taiwan Semiconductor 1.5KE12A B0G Zener TVS diode, 1500W peak pulse, 16.7V clamp, 10.2V standoff, DO-201 axial.
