**miracle** · MOSFETs · TO-220F

MPF20N50 from miracle, 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, pin 1 of the TO-220F; gate-source voltage is limited to ±30 V and the gate threshold voltage is 2 V to 4 V at VDS = VGS, ID = 250 µA. |
| 2 | D | passive | Drain, pin 2 of the TO-220F; drain-source voltage is rated at 500 V with 20 A continuous drain current at TC = 25°C. |
| 3 | S | passive | Source, pin 3 of the TO-220F; the body diode from source to drain carries up to 20 A continuous and 80 A pulsed. |
