FDD8780 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 25V N-channel MOSFET; the absolute maximum gate-to-source voltage is ±20V (VGS). |
| 2 | D | passive | DRAIN terminal of the 25V N-channel MOSFET; the absolute maximum drain-to-source voltage is 25V (VDS). |
| 3 | S | passive | SOURCE terminal of the 25V N-channel MOSFET; it is the reference for the gate-to-source rating (VGS ±20V). |
