IPP026N04NF2S from Infineon Technologies, in a TO-220-3. 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 | Gate | input | Gate of the N-channel MOSFET, rated for VGS from -20 V to 20 V, with gate threshold VGS(th) of 2.1 V to 3.4 V at VDS=VGS and ID=81 µA. |
| 2 | Drain | passive | Drain of the MOSFET, rated for 40 V drain-source breakdown voltage (V(BR)DSS) and 121 A continuous drain current at TC=25°C with VGS=10 V. |
| 3 | Source | passive | Source of the MOSFET and reference terminal for VGS; the datasheet gives a body-diode continuous forward current IS of 94 A at TC=25°C. |
