TVS (Transient Voltage Suppressor) and MOVs (Metal Oxide Varistor) are widely used in various applications to protect against electrical surge. The ROV14H820K-S TVS is one such device that is popular due to its actively efficient surge protection. This article will provide an overview of the ROV14H820K-S application field and working principle.

The ROV14H820K-S is a metal oxide varistor (MOV) that is specifically designed for protecting against high-energy surges. It is rated for single-line applications, meaning it can protect against a single high-energy surge on a single power line. The MOV’s high surge capabilities allow it to provide better protection than most other MOVs. Additionally, the MOV features low capacitance, allowing it to be more effective for use with digital equipment.

The ROV14H820K-S is mainly used for protecting against lightning surges, such as direct lightning strikes or indirect surge currents that occur when lightning systems dissociate in close proximity. This makes it well-suited for outdoor applications, including applications such as residential, commercial, and industrial power distribution systems. The device is also designed for applications with a high surge current, such as lightning induced ground potential rise areas. In such cases, the MOV is effective in protecting against the destructive voltage surge generated by the ground potential rise.

The ROV14H820K-S is also ideal for power supply systems in critical settings such as medical devices or communications systems. In such applications, surges should be prevented from damaging sensitive internal components that could cause system malfunctions. The MOV’s high rated current capability and its ability to dissipate high-energy surges make it well-suited for such applications.

The ROV14H820K-S works on the principle of a Zener diode. When an overvoltage is applied to the MOV, it acts as a Zener diode and diverts the excess voltage to ground. This allows the surge current to be safely diverted, thus reducing the risk of damage to the device or its surroundings. Additionally, the MOV’s highly efficient thermal dissipation ensures that the MOV can handle high-energy surges without becoming damaged.

The ROV14H820K-S is a highly efficient device for protecting against high-energy surge events. Its low capacitance makes it an ideal choice for digital applications, while its high surge capabilities make it well-suited for outdoor use. Furthermore, its Zener diode-based working principle provides efficient diverting of excess overvoltage away from the device without the need for an external fuse. Overall, the ROV14H820K-S is an excellent TVS for providing effective surge protection for various applications.
