The FDMC5614P is a Power MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) produced by Fairchild Semiconductor (now part of ON Semiconductor). This MOSFET is used in various power applications where efficiency and switching speed are crucial, such as power supplies, motor drivers, and other high-speed switching circuits.
Here’s a detailed breakdown of the requested information:
1. Package Type:
The FDMC5614P typically comes in a SOT-23 package, which is a small, surface-mount package with three terminals for the basic configuration, though the precise details for a specific version might differ.
2. Pin Function Specifications and Circuit Principle:
Pin Function Table (Example for a SOT-23 package, depending on specific variations) Pin Number Pin Name Pin Function Description 1 Gate (G) The gate terminal controls the switching of the MOSFET. It is used to apply a voltage to turn the MOSFET on or off. The gate-source voltage must be sufficiently positive to fully turn on the device. 2 Drain (D) The drain terminal is where the current flows when the MOSFET is on. This is the output of the switch, typically connected to the load or to the power supply in power applications. 3 Source (S) The source terminal is the common reference terminal, often connected to the ground or a lower potential. Current flows into the MOSFET through the source when the device is conducting.For a SOT-23 package, there are typically three terminals, but for other configurations, you might find more pins, with additional functionality such as heat dissipation, current sensing, or other specialized functions. Each package type (such as SO-8, TO-220) would have different pinouts and additional functions.
Circuit PrincipleIn simple terms, a MOSFET operates as a switch that controls current between the drain and source based on the voltage applied to the gate. When the gate-to-source voltage is sufficient, the MOSFET is "on," allowing current to flow from the drain to the source. When the gate-to-source voltage is low, the MOSFET is "off," and current does not flow.
For the FDMC5614P, the Drain is the output of the device, the Source is the reference (ground or a lower voltage), and the Gate is used to control the switching action.
