Circuit Principle Instructions for FDMS86200

The FDMS86200 is a MOSFET transistor, which means it has three main components: Drain, Source, and Gate.

Drain (D): This is the terminal where the current flows out of the MOSFET when it is on. The Drain is typically connected to the load in a circuit.

Source (S): The Source pin is where the current enters the MOSFET. This is generally connected to the ground or the lower potential side of the load in a switching configuration.

Gate (G): The Gate is the control terminal. When a voltage is applied between the Gate and Source (Vgs), it determines whether the MOSFET is on or off. When Vgs exceeds a certain threshold, the MOSFET switches on, allowing current to flow from the Drain to the Source.
