FDD6680AS 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 30V N-channel MOSFET; the gate-source voltage is rated at ±20 V (VGSS). |
| 2 | D | passive | DRAIN terminal; the datasheet names the solder mounting surface of the drain pins as the thermal reference for RθJC (Note 1, page 4). |
| 3 | S | passive | SOURCE terminal of the MOSFET, the return path for the drain current. |
