AUIRFB8405 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; controls the MOSFET, with a maximum gate-to-source voltage of ±20 V. |
| 2 | D | passive | Drain, connected internally to the mounting tab; VDSS is 40 V and continuous drain current is 185 A silicon limited and 120 A package limited. |
| 3 | S | passive | Source; the current return path of the MOSFET. |
