Cmos · MOSFETs · TO-252

CMD25N20A from Cmos, in a TO-252. 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 of the MOSFET; the gate-source voltage must stay within ±30 V (VGS rating).
2 D passive Drain of the 200 V N-channel MOSFET; continuous drain current is rated at 20 A at TC=25℃ (11.3 A at TC=100℃).
3 S passive Source of the MOSFET; continuous source current is rated at 20 A and pulsed source current at 80 A.
