Working Principle of IRF1404
The IRF1404 operates by applying a positive voltage between the gate and source terminals. Once the gate voltage exceeds the threshold, a low-resistance channel forms between drain and source, allowing very high current to flow. Removing the gate voltage turns the MOSFET OFF, enabling efficient high-speed power switching.
