1500 W bidirectional transient suppressor for 342 V rails
The 1.5KE400CA B0G: The bidirectional channel makes it suitable for AC lines or DC rails where the polarity is not fixed — the device clamps symmetrically in both directions, so installation orientation does not matter.
Clamping voltage and breakdown margin
The minimum breakdown voltage is 380 V, which sits 38 V above the 342 V standoff rating. 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.
