    can any one tell me the exact voltage at which irfz44n gets fully on.

    It is guaranteed to turn on well when its gate-source voltage is 10V. Some graphs in the datasheet show that a "typical" one needs less gate-source voltage but you cannot buy a typical one.

    The datasheet lists its max on-resistance to be 0.028 ohms when its gate-source voltage is 10V and it is cool.
    It is barely turned on with a current of at least 0.25mA when its threshold gate-source voltage is only 4V.
