P6KE400A

DOWO · TVS · DO-15

P6KE400A from DOWO, in a DO-15. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 K passive Cathode lead, marked by the color band on the unidirectional P6KE400A (VBR 380-420 V, VRWM 342 V, 600 W peak pulse power at 10/1000 µs).
2 A passive Anode lead at the end opposite the color band; the unidirectional P6KE400A clamps at 548 V max at IPP 1.09 A.
