IRFI9540GPBF-VB

VBsemi Elec · MOSFETs · TO-220F

IRFI9540GPBF-VB from VBsemi Elec, in a TO-220F. 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; the gate-source voltage is rated at ±20 V, with gate threshold voltage VGS(th) between -1 V and -2.5 V.
2 D passive Drain terminal; the drain-source voltage is rated at -100 V, with continuous drain current of -12 A at TC = 25 °C.
3 S passive Source terminal; it is the reference for the ±20 V gate-source rating and the body diode continuous current is -8.8 A.
