    Hello friends, I am working on a circuit, and i have got a part number FDW9926A which a dual n channet power trench MOSFET.
    But i am unable to know that how it works?
    If anyone know then please explain the working of that part.

    Do you know how N channel MOSFET work?

    Take a look at the datasheet, check for the pin 1 position.

    If you connect Drain(pin 8,1) to your load, Source (7,6,2,3) to ground and apply a voltage of 4.5volts to Gate(5,4) , you will get a RDS(ON) of 0.032ohm.

    If you check the datasheet, with 4.5volts at the Gate you will be able to supply 4.5amps to your load.

    Note that the power dissipation will be of 0.648Watts

    datasheet

    looks like two transistors in an 8pin dil package

    i don't know exactly how it is working, becoz when i power up the left side (1,2,3,4) then i m getting output at the 2nd side ( 5,6,7,8).

    so i m confused about the working of n-channel mosfet to due to this propoerty, it is working like an opto-isolator.
