The DO-201 (DO-27) axial body is a through-hole form factor that suits point-to-point wiring on terminal strips or PCB mounting with the lead bend formed to the hole pitch. The bulk packaging means the parts ship loose in a bag or tube, not on tape-and-reel, so the handling profile matches low-volume or prototype builds.","metaTitle":"1.5KE440CA B0G TVS Diode, 1500W, 376V Standoff, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE440CA B0G bidirectional TVS, 1500W peak pulse power, 376V reverse standoff, 602V clamp.
