20N50 from HXY MOSFET, in a TO-220F. 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 | G | input | Gate terminal of the 20N50 N-channel MOSFET; the datasheet gives a gate-to-source voltage rating of ±30 V and VGS(TH) of 2.0 to 4.0 V. |
| 2 | D | passive | Drain terminal of the 20N50; the datasheet gives a drain-to-source voltage VDSS of 500 V and continuous drain current ID of 20 A. |
| 3 | S | passive | Source terminal of the 20N50; the datasheet gives RDS(ON) below 0.3 Ω at VGS=10V and ID=10A, referenced to this pin. |
