Pin Functions for IRFR9120NTRPBF (TO-220):

Pin Number Pin Name Pin Function Description 1 Gate (G) Gate Terminal This pin controls the switching of the MOSFET. A positive voltage at the gate turns the MOSFET on, allowing current to flow between the Drain and Source. A gate-to-source voltage of around 5V to 10V is typical for turning the device on. 2 Drain (D) Drain Terminal This is the output terminal of the MOSFET. Current flows from Drain to Source when the MOSFET is turned on. In a typical N-channel MOSFET configuration, the drain is connected to the load. 3 Source (S) Source Terminal This pin serves as the input terminal for current. For an N-channel MOSFET, the source is typically grounded, or connected to the negative side of the load. When the MOSFET is on, current flows from Drain to Source.
