IRFB7430PBF 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 channel, with VGS rated at ±20V maximum and a gate threshold of 2.2V to 3.9V. |
| 2 | D | passive | Drain (also connected to the tab); VDSS is 40V and continuous drain current is 195A package limited (409A silicon limited). |
| 3 | S | passive | Source; the body diode runs from source to drain, with continuous source current of 394A. |
