Working Principle of IRFZ44ZSPBF

The IRFZ44ZSPBF is an enhancement-type power MOSFET, which uses electrical charge to control a low-resistance path for current to flow through. The device consists of a gate, drain and source. When a negative voltage is applied to the Gate, it turns the MOSFET ON and allows current to flow from the source to the drain. When the voltage is removed from the gate, the MOSFET is OFF and no current flows. The current-carrying capacity of the IRFZ44ZSPBF depends on the amount of the applied gate voltage. The higher the gate voltage, the higher the current-carrying capacity.
