MASPOWER · MOSFETs · TO-220
MS8N120FT from MASPOWER, in a TO-220. 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; gate-source voltage is ±20 V DC (±30 V transient) with threshold VGS(th) of 3.0 to 5.5 V at ID = 250 µA. |
| 2 | D | passive | Drain, also connected to the tab; drain-source voltage is 1200 V max and continuous drain current is 8 A at TC = 25 °C. |
| 3 | S | passive | Source; source-drain diode continuous current is 8 A typical and pulsed is 22 A typical. |
