TVB170MSB-L Circuit Protection

Thyristors, also called semiconductor controlled switches, are devices composed of four layers of alternately doped semi-conductive material, which conduct electricity in one direction only when triggered by a low current signal. Thyristors are used to control electrical currents in electrical equipment ranging from household appliances, to commercial and industrial machines, to lighting systems. The Jones TVB170MSB-L is a thyristor device designed to stabilize regulated voltages and control electrical current in the presence of significant noise levels. This article will discuss the application field and working principle of the TVB170MSB-L.

The Jones TVB170MSB-L is a three-terminal voltage regulator thyristor device—the term thyristor stands for a four-layer diode. It is a polarity-sensitive device that controls current and voltage, and can automatically detect, and switch current to the load, thus providing protection from hazardous voltage transients and power surges. The TVB170MSB-L can also be used inDC-DC chopper and unregulated AC power supply applications. It has a high surge current capability and low on-state voltage drop, and can be controlled by voltages as low as 1.2V.

The electrical principles behind the functioning of thyristors is based on the fact that the active layers of the semiconductor device have a resistance that changes dramatically with voltage, or in other words, a diode-like characteristics. When a voltage is applied across the thyristor, current flows in one direction. If the current is increased, the voltage across the active layer increases, and when it reaches the breakover or "trigger" voltage level, the thyristor switches and current can flow in both directions. The breakover voltage is determined by the characteristics of the materials used in the device. If the voltage decreases, the current will not flow and the device returns to its rest state.

The Jones TVB170MSB-L provides reliable voltage regulation, as well as high surge current capability, in the presence of significant levels of power line noise. It can handle overloads and irregular line transients without compromising its delicate circuitry, thus increasing its lifespan and reliability. The TVB170MSB-L is a perfect choice for a wide range of applications, including power supplies, DC-DC choppers, AC motor control, and lighting systems. It has a wide operating temperature range, as well as a low current leakage, and is capable of switching current quickly and efficiently.

In conclusion, thyristors are a cost-effective and reliable means of regulating current and voltage, and are widely used in a variety of electrical applications. The Jones TVB170MSB-L is a robust thyristor device that offers highly effective voltage regulation and current control. With its high surge current capability and low on-state voltage drop, the TVB170MSB-L is well suited to a variety of applications, including power supplies, DC-DC choppers, AC motor control, and lighting systems.
