Pinout and Pin Function Specifications for FQP47P06 (TO-220 Package)
The FQP47P06 is a P-channel MOSFET with the following pinout for the TO-220 package:
Pin Number Pin Name Pin Function 1 Gate (G) Controls the switching of the MOSFET. A negative voltage relative to the source is required to turn the MOSFET on. 2 Drain (D) The drain is where the current flows out of the MOSFET. This pin is typically connected to the load in most applications. 3 Source (S) The source is the input terminal for current. For a P-channel MOSFET, it is typically connected to a negative power rail. 4 (Tab) Drain The metal tab at the back of the package is internally connected to the drain pin (pin 2), allowing heat dissipation.Functionality of Each Pin
Gate (Pin 1): Function: The gate controls the conductivity of the MOSFET. The MOSFET operates as a switch. To turn it "on," a negative voltage relative to the source pin must be applied. If the gate-to-source voltage exceeds a certain threshold, the MOSFET will conduct and allow current to flow from drain to source. Use: This pin is typically controlled by a gate driver circuit that ensures the correct voltage is applied to switch the MOSFET on and off. Drain (Pin 2): Function: The drain is the output terminal of the MOSFET. In a switching application, this is where the load is connected. The current will flow from the drain to the source when the MOSFET is turned on. Use: When using the FQP47P06 in power regulation, this pin would typically be connected to the load side of the circuit. Source (Pin 3): Function: The source is where current enters the MOSFET. For a P-channel device like the FQP47P06, the source will typically be connected to a negative voltage rail. Use: In most applications, the source pin is connected to the high-side power supply in a power switching configuration. Tab (Pin 4): Function: The metal tab is connected internally to the drain pin. It serves as a thermal connection for heat dissipation to help manage the power dissipation of the device. Use: It is typically attached to a heat sink to improve heat dissipation.MOSFET Circuit Principles
The FQP47P06 is a P-channel MOSFET. When used in a circuit, the current flows from the source to the drain. The gate controls whether or not current can flow between the source and drain.
Turning On: When a negative voltage is applied between the gate and source, the MOSFET will turn on, allowing current to flow from the source to the drain. Turning Off: When the gate-to-source voltage is zero or positive, the MOSFET will be off, preventing current from flowing from the source to the drain.The principle of operation relies on the formation of an inversion layer between the source and drain when the gate-to-source voltage is sufficiently negative.
