WGP4N70SE from Wild Goose, in a TO-220. 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 (G)	input	Gate terminal; the absolute maximum rating table lists a ±30 V limit for the gate-source voltage, and VGS(TH) is specified at 2 V to 4 V for ID=250μA and VDS=VGS.
2	Drain (D)	passive	Drain terminal; the part is rated for a drain-source voltage VDSS of 700 V and a drain current ID of 4.0 A at Tj=25℃ (2.3 A at Tj=100℃).
3	Source (S)	passive	Source terminal; the body diode is rated for a maximum forward current of 4 A and a maximum pulsed forward current of 16 A.
