Transient Voltage Suppressors (TVS) are one of the most important protective electronic components in electronic circuits. In most applications, TVSs provide voltage protection and can help protect devices from high reverse transient voltages and instantaneous large surges and spikes. Desco manufactures a wide range of transient voltage suppression devices, including Varistors, Metal Oxide Varistors (MOVs), and Polymer PTCs. Of these, the V20E275PL2B7 is one of Desco\'s most popular Varistor products. This article explains the application fields of and working principles behind this Varistor.

Application Field

The V20E275PL2B7 is a Varistor with a self-restoring capacitance technology and a rated clamping voltage of 275 Volts (DC). This Varistor is designed to meet the highest quality standards, making it ideal for use in a wide range of industrial and consumer applications. It can be used in circuit boards and power supplies, automotive electronics, security systems, UPS systems, home appliances, and portable electronics. In most applications, the V20E275PL2B7 provides reliable power protection and can help devices operate more efficiently while also being more resistant to damage caused by transient voltage spikes.

Working Principle

The working principle of the V20E275PL2B7 is relatively straightforward. This Varistor is designed to detect and suppress voltage spikes. When an overvoltage occurs, the Varistor intakes a voltage and limits its amplitude to a safer, more manageable level. This works by creating a blocking effect, in which the Varistor acts as a high-resistance conductor. This way, it can limit excessive current flow as well as reduce voltage levels without creating a large voltage drop. The V20E275PL2B7 also has a self-resetting capacitance technology, which helps it to quickly and reliably reset itself after a spike is detected and dissipates. This helps to ensure that it remains effective and efficient.

In summary, the V20E275PL2B7 is an effective and reliable Varistor designed to provide effective power protection. It has a wide range of applications, including automotive electronics, circuit boards, and other consumer products, and it\'s self-resetting capacitance technology ensures it functions reliably and quickly. Its popularity continues to grow, as more and more industrial and consumer applications are in need of surge protection.
