TVS - Thyristors: TVB140NSB-L Application Field and Working PrincipleThyristor is a type of electronic component which belongs to the category of power semiconductor devices. It is a solid state device with four p-n junctions, which allows electrical current to flow only in one direction. The TVB140NSB-L is a voltage-controlled thyristor designed to provide a reliable solution for AC power control. This device has a wide applications range and can be used in a variety of applications such as power conditioning, current and voltage sensing, etc. In this article, we will discuss the application fields and working principles of TVB140NSB-L. TVB140NSB-L Application Fields The TVB140NSB-L thyristor is an excellent choice for a variety of power control applications. It offers a simple, effective and efficient power solution. It offers a wide range of current ratings from 20A to 600A with surge current capabilities up to 6kA. This device is primarily used in AC power control applications, such as the control of motors, heating elements, and lighting circuits. It is also widely used in the construction of power supplies, instantaneous power control, and static switching applications.Working Principle The TVB140NSB-L is a voltage-controlled thyristor that is activated when the control voltage reaches a certain level. It consists of four p-n junctions connected in the form of a bridge. When the control voltage reaches the turn-on level, the thyristor conducts with minimum voltage drop across its terminals. The device is then in the on-state and allows current to flow through the external circuit. The device can be turned off manually or by applying a reverse bias voltage across its terminals. The reverse bias voltage must be higher than the turn-off level, in order to turn the thyristor off.Advantages The TVB140NSB-L thyristor offers several advantages when compared to other power switches. It has a high thermal stability and offers good isolation from high dV/dt transients. It also offers fast and reliable switching, with low dynamic and static losses. Furthermore, this device has a long life and is designed for a wide range of more severe AC power systems. ConclusionIn conclusion, the TVB140NSB-L is an excellent choice for power control applications. It offers excellent electrical characteristics, fast and reliable switching, low dynamic and static losses, and a long life. This device is used in a variety of power control applications, such as the control of motors, heating elements, and lighting circuits. It is also widely used in the construction of power supplies, instantaneous power control, and static switching applications.
