TVSs (transient suppression devices), MOVs (metal oxide varistors) and ROV (radial lead overvoltage) protection components are popular components employed in industrial and manufacturing applications. The ROV07H681K-2 belongs to the ROV family and is used in applications involving protection against transient voltage spikes and surges. In this article, we’ll discuss the application field and working principle behind the ROV07H681K-2, as well as its advantages over other components.

Application Field of ROV07H681K-2

The ROV07H681K-2 is a radial lead overvoltage protection component with an identical form factor as the MOV, making it suitable for replacements in applications originally using MOV component. It works to protect users against damages due to overvoltage and overcurrent conditions. This includes overvoltage protection of devices such as TV sets, monitors and other consumer electronic equipment, in addition to industrial and power conversion applications. It can also be used for protecting against transient voltage surge like lightning strike and switching surge. Due to its ability to protect against transient surge, the ROV07H681K-2 is used in automobiles which require emergency power when voltage overload occurs. Generally, the applications which require overvoltage protection and pulse energy absorption will benefit from choosing the ROV07H681K-2.

Working Principle of ROV07H681K-2

The working principle behind the ROV07H681K-2 is rather simple. It employs non-linear elements to reduce the voltage level of high side of the circuit when it is exposed to overvoltage. When the voltage reaches a critical point, the ROV07H681K-2 will activate its overvoltage protection; that is, it will allow the current to flow through and reduce the load voltage to a safe level. Truly, this is done through non-linear current-voltage characteristics, which allow current to pass through the device in one direction when the voltage reaches a set value. Once this initial set value is passed, the voltage can no longer increase due to the non-linear current-voltage characteristic.

Aside from protection from transient voltage spikes and surges, the ROV07H681K-2 provides other features as well. This includes a high current rating, which is several orders of magnitude larger than other protection components. Moreover, the ROV07H681K-2 also provides self-healing properties, in which it will reset itself after being exposed to an overvoltage surge or transient voltage spikes. This makes it a useful tool in protecting against transient voltage surges in high-voltage applications.

Advantages of ROV07H681K-2

Overall, the ROV07H681K-2 provides several advantages compared to other protection components. Firstly, it provides superior protection against transient voltage surges and spikes compared to other similar components like the MOV. Secondly, it has a very high current rating, which is several orders of magnitude higher than that of most MOV components. Additionally, it also provides self-healing properties, which allow it to reset after being exposed to overvoltage. Lastly, its compact form factor makes it ideal for use in location with limited space.

Conclusion

In conclusion, the ROV07H681K-2 is an ideal protection component for applications which require overvoltage protection and pulse current absorption. In addition to providing superior protection against transient voltage surge, the ROV07H681K-2 also offers features like high current rating and self-healing properties. With its compact form factor, the ROV07H681K-2 is a highly effective protection component which is suitable for use in a variety of industrial and consumer applications.
