IRFB7434PBF 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 terminal; the datasheet limits the gate-to-source voltage VGS to ±20 V. |
| 2 | D | passive | Drain terminal; continuous drain current is 317 A (silicon limited) and 195 A (wire-bond limited) at TC = 25°C, with VDSS of 40 V. |
| 3 | S | passive | Source terminal; continuous source current IS is 317 A and pulsed source current ISM is 1270 A. |
