IRF3808PBF from Infineon Technologies, in a TO-220AB. 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-to-source voltage is limited to ±20 V, with a gate threshold of 2.0 V min to 4.0 V max at VDS = 10 V, ID = 250 µA. |
| 2 | D | passive | Drain (also connected to the mounting tab); VDSS is 75 V, with 140 A continuous drain current at TC = 25°C (package limited to 75 A) and 550 A pulsed. |
| 3 | S | passive | Source; carries the same current as the drain, and the body diode continuous source current is 140 A. |
