This gap ensures the diode does not conduct during normal rail ripple or steady-state overvoltage within the design tolerance. The wide temperature range does not derate the peak pulse power at the extremes — the 1500 W rating holds across the full range per the 1.5KE series datasheet. ## Through-hole DO-201 package and sourcing Housed in a DO-201AA (DO-27) axial leaded package, the 1.5KE400CA B0G is a through-hole part suited for point-to-point wiring or PCB mounting where the axial leads are bent and soldered. The bulk packaging means it ships loose in a bag or tube, not on tape and reel — a detail to confirm if your pick-and-place line expects reeled parts.","metaTitle":"1.5KE400CA B0G TVS Diode, 1500W, 342V Standoff, DO-201","metaDescription":"1.5KE400CA B0G bidirectional TVS from Taiwan Semiconductor, 1500W peak pulse power, 342V standoff, 548V clamp.
