CMF20N50 from Cmos, 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; the gate-source voltage is rated at ±30 V maximum, with a threshold of 2 V to 4 V at ID=250 uA. |
| 2 | D | passive | Drain; the drain-source voltage is rated at 500 V, and the continuous drain current for the TO-220F (CMF20N50) is 20 A at TC=25°C and 12 A at TC=100°C. |
| 3 | S | passive | Source; the continuous source (body diode) current is 20 A maximum and the pulsed source current is 60 A maximum. |
