UMW · MOSFETs · TO-220
FDP8440 from UMW, 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 terminal; gate-to-source voltage is rated ±20 V (VGSS), and the gate is the input for switching the 40 V N-channel MOSFET. |
| 2 | D | passive | DRAIN terminal; drain-to-source voltage is rated 40 V (VDSS) and continuous drain current is rated 277 A at TC=25°C (silicon limited). |
| 3 | S | passive | SOURCE terminal, the MOSFET source reference for gate drive and the drain-source rating. |
