RRH075P03TB1 Application Field and Working Principle

The RRH075P03TB1 is a type of Field Effect Transistor (FET) designed for high-speed switching applications in automotive, industrial, and consumer applications, among others. It has a wide drain-source breakdown voltage range, making it increasingly popular in various applications. The transistor is made up of two main components: a gate oxides and a field-effect gate oxide layer. It is manufactured using semiconductor wafers. This specific type of transistor is called a n-channel enhancement-mode field-effect transistor (MOSFET). Additionally, it can be subdivided into three types: Depletion-Mode FETs, Enhancement-Mode FETs and Bi-Polar Field-Effect Transistors (FETs). The RRH075P03TB1 belongs to the Enhancement-Mode FETs.

Understanding the working of field-effect transistors is essential for engineers as it provides a potential for creating power-efficient, high performance electronic switches. The gate of the transistor serves as a voltage-controlled switch, which can be turned on and off. To understand the mechanism better, we will discuss how the transistor works when a negative gate-source voltage is applied:

When no voltage is applied, there is no electric field in the MOSFET region. In other words, the gate is in the ‘off’ state, and no current flows through the source and drain electrodes. Therefore, when a negative gate-source voltage is applied, the electrons in the substrate would move back and away from the gate, creating a depletion region. The presence of the depletion region leads to the formation of an electric field, which creates an electrical potential barrier between the drain and the source. This potential barrier is known as the pinch-off voltage. Since current cannot flow through the depletion region, the drain and source currents remain zero.

The electric field created by the negative gate- source voltage induces a large number of electrons (electron-hole pairs) are created. This increases the concentration of free electrons in the channel region between the source and drain and enables the transistor to carry more current. This feature is known as the storing effect.

When the drain-source voltage is greater than the pinch-off voltage, current flows through the channel and the transistor is said to be in the \'on state\'. This current is referred to as drain current (ID). When the drain voltage is decreased, the electric field created by the negative gate-source voltage depletes, thus reducing the ID.

The gate-source voltage of the transistor acts as the control input in the transistor. In other words, the current flowing through the transistor can be controlled by the voltage applied to the gate. This enables engineers to design transistors that can be used in power electronics applications like power converters, motor control, and power switching devices.
