Working Principle of FQP22N30
The FQP22N30 operates by applying a positive voltage to the gate relative to the source. When the gate voltage exceeds the threshold level, an internal conduction channel forms, allowing current to flow from drain to source. Removing the gate voltage turns the MOSFET off, making it suitable for efficient high-speed switching applications.
