IRF9383MTR1PBF Working Principle

IRF9383MTR1PBF works by using the unique characteristics of a MOSFET, a type of field effect transistor. To understand the working principle of this component, some information about the structure of a MOSFET is important. A MOSFET’s structure is composed of three terminals; the gate, the source and the drain. The gate terminal is used to control the current flow between the source and the drain, depending on the electric field created by the gate which determines the current flow. The range of electric field between the gate and the source-drain region is called the ‘threshold voltage’, which is the difference between the gate voltage and the source-drain voltage.

In IRF9383MTR1PBF, when the source-drain voltage is increased above the threshold voltage, the current flow between the source and drain increases while the gate voltage stays constant. The resulting current is an exponential function of the threshold voltage. This component is used to control large amounts of current anywhere in the range of 1A to 10A with a gate- source voltage of just 4.5V.

To summarise, the functioning of this component relies on the electric field created by the gate voltage to control the current flow between the source and drain. By controlling the current in this way, the component is able to generate specific steady currents that can be used for any number of applications.
