TVS - Varistors, MOVs, is a type of electrical component that is capable of handling large voltage surges, providing transient electric current and also stabilizing line voltages. The ROV05H361K-2 is one of the most advanced products used in the industry and is suitable for a vast range of applications.

This device is particularly suited for protecting consumer electronics from ESD and surges with peak current ratings of 6.5 KA. It is typically used in LAN/Telecom and power supplies. It has an operational temperature range of -40°C to +125°C. The key features of ROV05H361K-2 are its fast response times and low-capacitance body, which makes it ideal for high speed data lines.

To understand the working principle of ROV05H361K-2, it is important to have a basic understanding of how varistors, MOVs or TVS components work. When a voltage surge is experienced, the component absorbs the extra voltage and thus limits the stress on the other components of the electrical circuit. The device works by exploiting the non-linear behavior of the zinc oxide-based varistor material that comprises its ceramic body. This material has a varistor voltage, which for ROV05H361K-2 is approximately 360V for a 10/1000μs waveform. This means that when the external voltage reaches 360V, the varistor absorbs the entire surge and clamping will occur.

The varistor voltage of the component is defined as the voltage at which it starts conducting and is determined by the size and type of material used. For example, the zinc oxide-based varistor material typically has a varistor voltage of 130 volts for a 10/1000μs waveform. As the external voltage increases, the body of the device becomes more conductive and thus more current can flow through it. When the voltage reaches the varistor voltage, the device begins to clamp the voltage and limit the current flowing through it.

Finally, the ROV05H361k-2 also has a back-to-back diode protection built-in, allowing it to absorb transient voltages of up to 150V above the varistor voltage. This ensures that the device can protect circuits from even large and potentially damaging voltage surges.

In conclusion, it is clear that the ROV05H361K-2 is a powerful and versatile TVS device that is capable of protecting circuits from a wide variety of causes, from ESD and surges to large transient voltages. Its fast response time and low-capacitance body make it ideal for use in high-speed data lines in LAN/Telecom and power supplies.
