IRFB4110PBF

Infineon Technologies · MOSFETs · TO-220

IRFB4110PBF from Infineon Technologies, in a TO-220. 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 of the HEXFET; gate-to-source voltage is rated ±20 V (VGS), and the gate threshold is 2.0 V to 4.0 V.
2 D passive Drain of the MOSFET, electrically connected to the metal mounting tab; rated VDSS 100 V with continuous drain current of 180 A (silicon limited) or 120 A (package limited) at TC = 25°C.
3 S passive Source of the MOSFET and reference for VGS; the body diode continuous source current is rated 170 A at TJ = 25°C.
