Power line protection is not supported — this is a unidirectional device for DC rails, not AC mains. The single-channel design protects one line per package; for bidirectional or multi-line protection, pair two devices or choose a bidirectional variant from the same family. ## Package and board integration Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE220AHA0G mounts through-hole. The DO-201 footprint is standard across the 1.5KE series — the same board layout accepts any voltage variant, simplifying BOM consolidation for different rail protection levels. Supplied in Tape & Box (TB) format, suitable for hand-insertion or selective soldering. The axial leads require manual or wave-solder assembly; no reflow profile applies.","metaTitle":"1.5KE220AHA0G TVS Diode, 1500W, 185V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE220AHA0G automotive TVS, 1500W peak pulse, 185V reverse standoff, AEC-Q101 qualified.
