IRLB8748PBF 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 of the HEXFET; gate-to-source voltage is limited to ±20 V per the absolute maximum ratings. |
| 2 | D | passive | Drain terminal; the device is rated for a 30 V drain-to-source voltage (VDSS) and carries the continuous drain current. |
| 3 | S | passive | Source terminal; the reference for gate-to-source voltage and the return path for drain current. |
