IRLB8748PBF

Infineon Technologies · MOSFETs · TO-220AB

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.
