Working Principle of IRF1405
The IRF1405 operates by applying a positive voltage to the gate relative to the source. Once the gate threshold is exceeded, a conductive channel forms between the drain and source, allowing very high current to flow. Removing the gate voltage switches the MOSFET OFF, making it suitable for efficient high-speed power switching.
