IRFB4310ZPBF

Infineon Technologies · MOSFETs · TO-220-3

IRFB4310ZPBF from Infineon Technologies, in a TO-220-3. 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; the datasheet limits gate-to-source voltage to ±20 V (absolute maximum rating).
2 D passive Drain terminal rated for VDSS 100 V, with continuous drain current of 127 A (silicon limited) at TC = 25°C and 120 A (package limited).
3 S passive Source terminal; the body diode is rated for 127 A continuous source current and 560 A pulsed source current.
