**Minos** · MOSFETs · TO-263

MPT045N08S from Minos, in a TO-263. 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; drive with VGS up to ±20 V, with threshold VGS(th) of 2.0 to 4.0 V at ID=250µA and RDS(on) specified at VGS=10V. |
