Thyristors - SCRsThyristors, also commonly known as Silicon Controlled Rectifiers (SCRs), are three-lead power semiconductor devices with a wide range of applications. This article provides an overview of C158N thyristors and will discuss their field of use as well as their working principles.C158N thyristors are widely used in various electronic circuits and systems. They are suitable for a variety of power applications, such as commutating motor drives, regulated power supplies, and motor speed control systems. C158N thyristors are also used for temperature and power control in heating systems, such as industrial furnaces, ovens, water heaters and boilers. In addition, they are often found in various audio amplifiers and low- frequency power supply designs.To understand the working principle of C158N thyristors first requires an understanding of how a basic thyristor normally works. Generally, thyristors are controllable solid-state switches used to control the flow of electric current in an electrical circuit. They are controlled by applying a voltage to their gate terminal, which causes them to switch on or off depending on the applied voltage.The C158N thyristor is similar to a basic thyristor in its operation, with a few key differences. It has two additional electrodes, the gate and auxiliary terminals. The gate terminal is used for controlling its switching state, while the auxiliary electrode helps to regulate its working voltage. Additionally, its forward voltage drop is dramatically reduced compared to a basic thyristor. This makes it suitable for applications with higher voltages and currents.In operation, the control of the C158N thyristor is dependent on its gate voltage. When the gate voltage is below 0.7V, the thyristor is off and no current flows. Conversely, when the voltage exceeds 0.7V, the thyristor switches on and the current starts to flow. It is important to note that the current only flows for the period of time that the applied voltage remains in excess of 0.7V. Once the voltage drops below 0.7V, the thyristor switches off.The C158N thyristor is a powerful device with a wide range of applications. It is suitable for use in commutating motor drives, regulated power supplies, motor speed control systems, audio amplifiers, industrial heating systems, and low-frequency power supply designs. Its ability to respond quickly to gate voltage changes makes it a useful device for controlling current in a wide variety of electronic applications. The simplicity and reliability of the C158N thyristor make it a popular choice for a number of applications. Additionally, its forward voltage drop is significantly lower than a standard thyristor, making it suitable for higher voltage and current applications. Its gate terminal also allows it to be easily controlled, making it suitable for a variety of power control applications. In conclusion, the C158N thyristor is a reliable, efficient, and versatile power device. Its wide range of applications and simple operation make it a popular choice for many circuit designs. Its ability to respond quickly to gate voltage changes and its low forward voltage drop make it suitable for a variety of power control applications. With its stability, efficiency, and reliability, the C158N thyristor is an ideal choice for any power application.
