TVS – Varistors, MOVs, are surge protection components used to protect electronic circuits and equipment from destructive transient overvoltage and high-energy impulses. With dampened high-energy impulses, these components provide electrical circuit protection as a critical part of the system.

A specific type of TVS – MOV, is the ROV07H820K-S. This component is commonly used in automotive applications such as starter motors, alternators, and contactors. Additionally, ROV07H820K-S protects various edge-connector interfaces in industrial automation, and in other industrial equipment, such as programmable logic controllers.

The ROV07H820K-S is a low-power, high-clamping, MOV (metal oxide varistor) with a maximum peak current of 8A. Additionally, the ROV07H820K-S features a working voltage of 500V and a peak-clamping voltage of 700V.

The ROV07H820K-S is constructed from a zinc-oxide-based ceramic material, mounted on an epoxy resin with a flame retardant. The epoxy resin acts as a protective coating over the MOV and dissipates the heat while protecting against moisture and other environmental factors.

The ROV07H820K-S is characterized by fast response time and a minimal height profile. Its small dimensions also add to its usability in tight-fit applications, such as those in an automobile.

The ROV07H820K-S is an ideal component for transient voltage surge protection in automobile applications. Its small size, low-power rating, and high-clamping-voltage make it indispensable, as it can be used in a variety of circuits in an automotive setting, across different applications.

In operation, the ROV07H820K-S functions to protect sensitive circuitry from transient overvoltage. When an overvoltage surge occurs, the device’s zinc-oxide-based ceramic material conducts and limits the overvoltage to a safe level. The device’s epoxy resin coating acts as a heat sink, while its small size ensures that it responds quickly to a transient overvoltage.

Finally, the device’s ability to safely absorb and disperse overvoltage provides necessary protection for sensitive equipment and circuits, and is necessary for the safe and reliable operation of modern electronic components.
