Working Principle of IRF9510 MOSFET

The IRF9510 operates as a P-Channel enhancement-mode MOSFET, meaning it conducts when a sufficiently negative voltage is applied to the gate relative to the source. When this gate-source voltage reaches the threshold, the channel forms and allows current to flow from source to drain. This behavior makes the device useful for high-side switching, voltage regulation, and load-control applications where negative gate drive is preferred.
