Working Principle of IRFZ48
The IRFZ48 operates by applying a positive voltage to the gate relative to the source. Once the gate voltage exceeds the threshold level, a conductive channel forms between the drain and source, allowing high current flow. Removing or lowering the gate voltage turns the MOSFET OFF, enabling efficient and fast power switching.
