# MOT9N50F

**MOT** · MOSFETs · TO-220F

MOT9N50F from MOT, 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 | Gate | input | Gate terminal; the datasheet rates gate-source voltage VGSS at ±30 V. |
| 2 | Drain | passive | Drain terminal; the datasheet rates drain-source voltage VDSS at 500 V and continuous drain current ID at 9 A (TC=25°C). |
| 3 | Source | passive | Source terminal; it is the reference for the ±30 V gate-source rating and carries the body-diode maximum continuous current of 9 A. |
