4080K from Shenzhen Fuman, 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 limited to ±20 V, with threshold VGS(th) of 1.1 V min to 2.4 V max at VDS=VGS, ID=250 μA. |
| 2 | D | passive | Drain (also the exposed tab); rated 40 V VDSS and 80 A continuous at TC=25℃, 210 A pulsed. |
| 3 | S | passive | Source; body diode from source to drain is rated 80 A continuous and 210 A pulsed. |
