The SI4620DY-T1-E3 is a high power single N-channel enhancement-mode power MOSFETs for use in low voltage, high current switching applications. In order to understand the application fields and working principle of the SI4620DY-T1-E3, it is important to understand the structure and operation of the MOSFET. Here we will look at what a MOSFET is and discuss the working principle of the SI4620DY-T1-E3.

What is a MOSFET?

A MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor) is a type of transistor used in a variety of electronic applications. It is a four-terminal device with three terminals grouped as the source (S), gate (G) and drain (D) and one terminal referred to as the body or substrate (B). A MOSFET works when a voltage is applied across the gate and source terminals, creating an electric field that is responsible for controlling the flow of current between the drain and source terminals.

Working Principle of the SI4620DY-T1-E3

The SI4620DY-T1-E3 is an enhancement-mode power MOSFET. In order for it to operate, a voltage must be applied to the gate terminal which then creates an electric field between the gate and source terminals. This electric field creates a conductive path between the source and drain by a process called impact ionization, which is when the electrons or holes created in the gate-to-source electric field are accelerated by this strong electric field and “impact” the SiO2-Silicon interface. This impact of electrons and holes on the interface creates a conductive path between the source and drain, allowing current to flow from the source to the drain.

This is the basic principle how the SI4620DY-T1-E3 works. In order to understand how this device can be applied, it’s important to consider how this device performs when it is used in various applications.
