IRFB4020PBF-JSM

JSMSEMI · MOSFETs · TO-220-3L

IRFB4020PBF-JSM from JSMSEMI, in a TO-220-3L. 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; gate-source voltage is rated ±20 V maximum, with a threshold of 2.0 V min to 4.0 V max at VDS = VGS, ID = 250 µA.
2 D passive Drain, which is also connected to the TO-220 tab; rated for 200 V VDSS and 18 A continuous drain current (72 A pulsed).
3 S passive Source; connected to the body diode anode, which has a continuous current of 18 A and a forward voltage of 1.4 V max at ISD = 9 A.
