Clamping voltage and pulse current for a 376 V rail
The 1.5KE440CA B0G: With 1500 W of peak pulse power handling in a DO-201AA axial-lead package, this part is sized for industrial power supplies, motor-drive DC buses, and telecom rectifiers where a single high-energy surge must be shunted without the diode failing short.
Temperature range and package fit
The junction temperature range spans -55°C to 175°C, covering the full industrial and automotive under-hood ambient envelope. 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.
