IRFB7430PBF

Infineon Technologies · MOSFETs · TO-220AB

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.
