Pin Function Specifications and Circuit Principle Instructions
Below is the detailed explanation of the pins, their functions, and usage.
Pin Number Pin Name Pin Function Description Pin 1 Gate (G) Gate Terminal The Gate pin controls the switching of the MOSFET. It is used to turn the MOSFET on and off by applying a voltage relative to the Source terminal. The Gate is insulated from the rest of the device, making it voltage-controlled. In an enhancement-mode MOSFET like the IRF7820, a positive voltage turns the device on, while 0V (or negative voltage) turns it off. Pin 2 Drain (D) Drain Terminal The Drain pin is where the current exits the MOSFET, and it is typically connected to the load in a switching application. The Drain is where the MOSFET switches on or off, depending on the voltage applied to the Gate pin relative to the Source. This pin allows for high power to be transferred when the MOSFET is conducting, and its voltage can vary based on load conditions. Pin 3 Source (S) Source Terminal The Source pin is the reference terminal of the MOSFET. It is typically connected to ground in low-side switch configurations, or the positive supply in high-side switches. The Source serves as the input for current that flows through the MOSFET to the Drain. In this configuration, the Source is where the current enters the device when it's on.Detailed FAQ for IRF7820TRPBF Pin Functions
