Working Principle of IRFZ34
The IRFZ34 operates by applying a positive gate-to-source voltage that creates a conductive channel between the drain and source. Once the gate voltage exceeds the threshold level, the MOSFET turns ON and allows current flow. Removing or lowering the gate voltage switches the device OFF, enabling efficient high-speed power control.
