FDD6776A from UMW, in a TO-252. 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 of the MOSFET; the datasheet rates gate-to-source voltage VGS at ±20 V. |
| 2 | D | passive | DRAIN terminal of the MOSFET; the datasheet rates drain-to-source voltage VDS at 25 V. |
| 3 | S | passive | SOURCE terminal of the MOSFET; it is the reference for the VGS and VDS ratings. |
