Pinout Description for IRLML6344TRPBF (SOT-23 package)

The SOT-23 package typically has 3 pins for this type of MOSFET.

Pin Number Pin Name Pin Function Description Pin 1 Gate (G) The Gate terminal controls the on/off state of the MOSFET. A positive voltage is applied to turn the MOSFET on, and a zero or negative voltage turns it off. Pin 2 Drain (D) The Drain is where the current flows from when the MOSFET is on. It’s connected to the load side of the circuit. Pin 3 Source (S) The Source is the terminal through which the current flows into the MOSFET. In an N-channel MOSFET like this, it is typically connected to ground or a lower potential.

Schematic and Working Principle

Gate (G): When a voltage is applied to the gate, it creates an electric field that allows current to flow between the Drain and Source. The MOSFET operates as a switch, either allowing current to pass (when gate voltage is sufficiently positive) or stopping current flow (when gate voltage is zero or negative). Drain (D): The current flows out of the Drain when the MOSFET is conducting. It is the connection point to the load. Source (S): The current enters the Source when the MOSFET is conducting. It typically connects to the ground or the negative side of the circuit in an N-channel configuration.
