TVS - Varistors, MOVs (metal-oxide varistors) are essential components in many circuit designs. MOVs provide protection against high-energy voltage transients, while Varistors can be used as voltage regulating components, acting as either voltage dividers or to reduce the peak voltage before it reaches other components. These devices are also important for electrostatic discharge protection, as well as providing current-limiting capability. The V202CA60 is a versatile and highly reliable protection product, designed for low-voltage applications.

The V202CA60 is a general-purpose Varistor with a voltage coefficient of 2 volts (ΔV/V=2) and a capacitance of 60 picofarads (pF). It is a high-grade, low-power Varistor with a rated voltage of 48 volts (Vrms) and a rated current of 0.2 Amps (Imax). The device is constructed of a zinc-oxide (ZnO) varistor element, which is connected to twoABS plastic terminals for reliable connections. The Varistor has a flat termination on one side, which allows it to be easily and securely mounted onto a circuit board. The V202CA60 features a high power dissipation to ensure reliable long-term operation. The device is also designed to provide maximum protection against high-energy ESD events.

The V202CA60 can be used in a variety of applications. It is particularly suitable for low-voltage power circuits, where it performs the important role of protecting downstream components from potentially hazardous voltages. The Varistor can also be used in a circuit as a voltage regulator, providing a predictable voltage output. It is also ideal for providing electrostatic discharge (ESD) protection in systems such as data and audio equipment. Furthermore, the device is suitable for use in applications such as temperature measurement, where a precise voltage source is required.

The working principle of the V202CA60 is based on the physical properties of zinc-oxide (ZnO). ZnO is a non-polar material, which has an extremely high resistance to electric fields. When the Varistor is subjected to a voltage that is lower than its rated value, its resistance is extremely high, causing no current to flow through the device. However, when a higher voltage is applied, the ZnO structure breaks down. The breakdown generates a varying amount of charge carriers, which result in a decrease in device resistance. This process is known as the Zener breakdown, and it is the basis of Varistor operation.

Once the breakdown process has occurred, the Varistor will remain in its low-impedance state until the external voltage drops to a level that is lower than the device’s rated value. This reduces the risk of secondary transients due to the internal capacitance of the device. The V202CA60 is a suitable device for a range of applications, as it offers high-grade protection against high-energy voltage transients, as well as the ability to provide accurately regulated voltages.
