P6KE51A

DOWO · TVS · DO-15

P6KE51A 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 end of the unidirectional TVS, marked by the color band; for P6KE51A VBR is 48.45 to 53.55 V at 1 mA, VRWM 43.6 V, and VC max 70.1 V at IPP 8.56 A.
2 A passive Anode end of the unidirectional TVS (the lead opposite the color band); rated for 600 W peak pulse power with a 10/1000 µs waveform.
