IRFU7440PBF from Infineon Technologies, in a IPAK. 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 control input of the N-channel MOSFET, rated for a maximum gate-to-source voltage of ±20 V. |
| 2 | D | passive | Drain terminal, rated for 40 V minimum drain-to-source breakdown voltage (VDSS) and 180 A silicon-limited (90 A package-limited) continuous current, and connected to the mounting tab. |
| 3 | S | passive | Source terminal, carrying up to 90 A continuous current (wire-bond limited) and the body-diode current of up to 180 A. |
