A TVS, or Transient Voltage Suppressor, is a type of voltage regulating device used to protect sensitive electronic components from power surges. TVSs, or voltage protecting diodes, are commonly used in a variety of applications, including communication, automotive, industrial, and lighting, to protect vulnerable circuits and semiconductors from over- and under-voltage conditions.

The ROV05-391K-S-2 is a type of TVS, known as a metal oxide varistor (MOV). The MOV is a special form of voltage regulating device that uses a special metal oxide material, called a varistor, to absorb electric energy from a surge or spike. This process works by creating a short circuit between two layers of metal oxide material during an overvoltage event, thus allowing excess current to be dissipated safely. This eliminates the risk of electrical fires or damage to associated components.

The ROV05-391K-S-2 has several advantages over other types of TVSs, such as lower cost, higher current-handling capacity, and increased EMI filtering. In addition, the ROV05-391K-S-2 has a higher peak pulse power rating, a lower maximum peak value which helps protect against surges in both low and high frequencies, and a longer life due to the improved capacitance. All of these factors contribute to the increased safety and reliability of the ROV05-391K-S-2.

The applications for the ROV05-391K-S-2 are broad. It is commonly used in industrial and medical equipment, automotive systems, consumer electronics, and communication products to protect from surges. In addition, it is also used in telecommunications systems, data centers, and off-grid energy systems. However, it is not suitable for protecting against line-connected equipment since it is highly sensitive to overvoltage and cannot operate above the voltage rating.

The working principle of the ROV05-391K-S-2 is fairly straightforward. When an overvoltage event occurs, the electrical current is directed through the varistor, where it is absorbed and dissipated as heat. The varistor then acts as a short circuit, allowing a large amount of current to quickly dissipate through its contacts. This absorption and dissipation process helps to protect the vulnerable electronic components of the system from damage.

In summary, the ROV05-391K-S-2 is a type of metal oxide varistor, or TVS, which is used to protect sensitive electronic components from power surges. It has a peak pulse power rating, a higher current-handling capacity, and increased EMI filtering, allowing it to be used in a variety of applications. Its working principle is to absorb and dissipate excess current during an overvoltage event, thus protecting the vulnerable components of the system.
