Working Principle of FQP24N08
The FQP24N08 operates by applying a positive voltage to the gate relative to the source. When this voltage exceeds the threshold level, a conductive channel forms between drain and source, allowing current to flow. Removing the gate voltage turns the MOSFET off, making it highly efficient for fast and repetitive switching tasks.
