CMF20N50B

Cmos · MOSFETs · TO-220F

CMF20N50B from Cmos, 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; maximum gate-source voltage is ±30 V and the gate threshold voltage is 2 V min to 4 V max at VGS=VDS, ID=250uA.
2 D passive Drain; maximum drain-source voltage is 500 V and continuous drain current is 20 A (marked 20* for the CMF20N50B) at TC=25°C.
3 S passive Source; continuous source (body diode) current is 20 A max and pulsed source current is 60 A max.
