AUIRFP4568 from Infineon Technologies, in a TO-247AC. 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 channel, with VGS rated at ±30 V maximum and a gate threshold of 3.0 V to 5.0 V at ID = 250µA. |
| 2 | D | passive | Drain; VDSS is 150 V and continuous drain current is 171 A at TC = 25°C. It is also connected to the mounting tab (package outline lists 4 - Drain). |
| 3 | S | passive | Source; carries the continuous source (body diode) current up to 171 A and is the return for the gate drive. |
