**miracle** · MOSFETs · TO-220F

MPF18N50 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 control input with a gate-source voltage rating of ±30 V and a threshold of 2 V to 4 V at VDS = VGS, ID = 250 µA. |
| 2 | D | passive | Drain terminal with a drain-source voltage rating of 500 V and continuous drain current of 18 A at TC = 25°C (72 A pulsed). |
| 3 | S | passive | Source terminal and current return path, carrying up to 18 A continuous at TC = 25°C. |
