N Mosfet Schaltung. If the mosfet is a p channel or pmos fet then the source and drain are p regions and the body is a n region. N channel mosfet are available at mouser electronics.
Small signal mosfet 200 mamps 60 volts n channel to 92 features aec qualified ppap capable this is a pb free device maximum ratings rating symbol value unit drain source voltage vdss 60 vdc drain gate voltage rgs 1 0 m vdgr 60 vdc gate source voltage continuous non repetitive tp 50 s vgs vgsm 20. Depending on the voltage quantity and type negative or positive determines how the transistor operates whether it turns on or off. To turn the mosfet on we need to raise the voltage on the gate.

About irf840 the irf840 is an n channel power mosfet which can switch loads upto 500v. An n channel mosfet is made up of an n channel which is a channel composed of a majority of electron current carriers. Then the p channel mosfet is used to switch the positive supply to the motor for forward direction high side switching while the n channel mosfet is used to switch the negative supply to the motor for reverse direction low side switching. To turn it off we need to connect the gate to ground.
