TVS - Varistors, MOVs

Varistor and Metal Oxide Varistor (MOV) are two major types of Transient Voltage Suppressors (TVS). These TVSs are designed to protect electronic devices by clamping transient voltages developed during the voltage surge events. A common example of these components is the ROV05-301K-S model.

Application Field

The ROV05-301K-s belongs to the MOV’s family. Its application fields include telecommunication systems, ICT/ICT-X systems, automotive supply systems, aeronautical systems, and power supplies for electronic devices. Here, the ROV05-301K-s is used for lightning and transient surge protect in the form of a TVS. As electrical surges can significantly damage electronic components, MOVs are a suitable protection solution.

Working Principle

Metal Oxide Varistors are nonlinear variable resistors that reduce instantaneous overvoltages within systems. It is composed of press ceramic disc with metal oxide material. When an overvoltage surge occurs in a circuit, the MOV offers a low-resistance path, allowing the surge current to flow through the MOV. This action diverts the current away from the sensitive semiconductor components and ensures the safety of the circuit.

Characteristics

One of the key benefits of the ROV05-301K-S is its low capacitance, which makes it well-suited for placing in circuits with higher signal speeds such as high-speed data lines. These components are also available with an optional integral transient filter for added protection. In addition, they are designed using state-of-the-art materials with superior reliability and performance. This allows them to have extended life cycles and a maximum working voltage of 5,000V.

Conclusion

The ROV05-301K-S model is a popular MOV that has a variety of applications in electronics and industrial systems. It is capable of providing fast and reliable protection when overvoltage surges occur in the circuit. Its various characteristics, such as low capacitance and extended life cycles, make it an excellent choice for many industrial and electronic applications.
