TVS (Transient Voltage Suppressor), MOVs (Metal Oxide Varistor) and ROV07-621K-2 are three commonly used surge protection solutions employed in various industries. ROV07-621K-2 is a nonlinear multilayer transient voltage suppressor in the form of a dual cathode diode. Let\'s take an in-depth look at its application field and working principle.

The typical application area of ROV07-621K-2 is power line surge protection. In the communication and industrial control fields, it plays an important role of filter waves and protects the connected equipment from damage due to lightning and high surge transients. The device is also suitable for protecting the electric circuits of household appliances, switch power, UPS, communication networks and related equipment.

As for the working principle of ROV07-621K-2, it operates by absorbing the surge and clamping the voltage down to safe operating levels. There are two metal oxide dielectric layers (MOV), with each layer consisting of a series of layers of special layered metal oxides which are encased in a robust ceramic body. The two metal oxide dielectrics are arranged in series and provide series electrical connection for the device. This series connection allows the device to clamp the voltage down to a safe level. When a surge is applied, both metal oxide dielectrics charge up to their maximum permissible rated voltage and the excess current is diverted to the external circuit elements. The device thus provides effective protection from over-voltage transients.

In addition, the ROV07-621K-2 features a number of other important features such as high surge tolerance, low leakage current and resistance to over-voltage transients. It also offers excellent thermal shock characteristics, high reverse energy rating and low capacitance. This device also has an extended working temperature range from -40°C to +85°C, making it suitable for installation in both indoor and outdoor applications.

In conclusion, ROV07-621K-2 can provide effective protection against high voltage transients and serve as an effective surge protection solution in a variety of industries. Its ability to control voltage transients and its extended working temperature range make it an ideal choice for a wide range of applications.
