FDD6685 from TECH PUBLIC, 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; gate-source voltage limit is ±20 V, with threshold VGS(th) of -1 V min to -3 V max at ID=-250 µA. |
| 2 | D | passive | Drain; drain-source voltage -30 V, continuous drain current -80 A at TC=25°C, pulsed -200 A (also connected to the tab per the package drawing). |
| 3 | S | passive | Source; RDS(ON) 8 mΩ max at VGS=-10 V, ID=-20 A and 11 mΩ max at VGS=-4.5 V. |
