Breakdown occurs at 28.5 V minimum, and the clamping voltage is held to 41.4 V at the rated 38 A peak pulse current — this 13 V window between breakdown and clamp defines the energy absorbed during a transient; a downstream 60 V-rated MOSFET or capacitor sees a safe voltage even under a full 1.5 kW strike. The 1500 W peak pulse rating is tested with a 10/1000 µs waveform per the TVS industry standard — a shorter pulse (e.g. 8/20 µs) allows a higher peak power, but the 1.5 kW figure is the conservative anchor for a 24 V rail protection budget. ## Package and board-fit for the DO-201 axial form Supplied in a DO-201AA (DO-27) axial-lead package, the 1.5KE30AHB0G mounts through-hole — the lead diameter and body length are standard for 1.5 kW TVS diodes, so the PCB footprint matches existing DO-201 land patterns without a layout change. The bulk packaging means parts ship loose in a bag or tube — no tape-and-reel, so hand-insertion or wave-solder assembly is the expected process; for automated lines, verify the lead forming and cut length against your insertion machine's feeder.","metaTitle":"1.5KE30AHB0G TVS Diode, 1.5kW, 25.6V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE30AHB0G Zener TVS, 1500W peak pulse, 25.6V reverse standoff, AEC-Q101 automotive qualified.
