Pinout for IRLL014NTRPBF: Pin Number Pin Name Pin Function Pin 1 Drain (D) The drain pin is connected to the external circuit where the power or load is managed. This pin carries the output current from the device. Pin 2 Gate (G) The gate controls the switching of the MOSFET. A voltage applied to the gate relative to the source controls whether the MOSFET is on or off. Pin 3 Source (S) The source pin is typically connected to the lower side of the load or to ground. This is where current flows into the MOSFET. Pin 4 Drain (D) This is the second drain pin (same as Pin 1). It is used for enhanced power handling and is typically connected to the power line or load. Detailed Pin Function Explanation: Drain (D): This is where the current exits the MOSFET. The voltage drop across the MOSFET is controlled by the gate-source voltage. In power applications, the drain is often connected to the power supply or load. Gate (G): The gate pin is the input for controlling the MOSFET. A positive voltage (relative to the source) turns the MOSFET on, allowing current to flow from drain to source. A voltage of zero or negative relative to the source turns the MOSFET off, blocking current flow. Source (S): The source is connected to the reference voltage (often ground) in the circuit, providing a return path for the current. Drain (D) (Secondary Pin): The additional drain pin allows the component to handle more current and manage power more efficiently. This is useful for applications requiring high current handling. Circuit Principle:The MOSFET operates as a switch. When a voltage is applied to the gate (greater than the threshold voltage relative to the source), the MOSFET turns on, allowing current to flow from the drain to the source. When the gate voltage is removed (or reversed), the MOSFET turns off, and current flow is blocked. This switching mechanism is essential in power regulation, such as in power supplies and motor control circuits.
