Working Principle of IRF9610 MOSFET

As a P-Channel enhancement-mode MOSFET, the IRF9610 remains OFF when the gate and source voltages are equal. When a sufficiently negative voltage is applied to the gate relative to the source, the device turns ON, allowing current to flow from source to drain. This behavior makes it suitable for high-side switching arrangements. Its smooth transfer characteristics and low gate charge also make it advantageous for analog audio stages where signal linearity is critical.
