WGU5N65SE

Wild Goose · MOSFETs · TO-251

WGU5N65SE from Wild Goose, in a TO-251. 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 Gate input Gate terminal of the MOSFET; the datasheet gives a gate threshold of 2 to 4 V at ID=250 μA and gate-body leakage tested at VGS=±30 V.
2 Drain passive Drain terminal of the MOSFET; rated for BVDSS of 650 V and drain current of 5.0 A at Tj=25℃, with RDS(on) of 2.50 Ω max at VGS=10 V.
3 Source passive Source terminal of the MOSFET, the reference for the gate and drain ratings; maximum diode forward current is 4 A and maximum pulsed forward current is 16 A.
