TVS-Varistor, MOV is a common protection device used in power electronics systems. The varistor, also called Voltage Dependent Resistor (VDR) is made up of ceramics and metal materials. The purpose of using such devices are to protect the circuits and other devices from voltages and currents above their normal operating level. The V360RA8 series is a range of TVS-Varistor, MOVs designed to protect circuits and equipment from overvoltage conditions and provide excellent EMI/RFI attenuation strength and excellent surge absorption.

The V360RA8 series components use a multi-tab configuration, with each tab containing a reversed biased MOV device. The main difference between the V360RA8 series and conventional components is the number of tabs. The V360RA8 series components have 8 tabs, allowing for superior performance compared to other solutions with fewer tabs. The 8 tabs are spaced evenly, forming a 360-degree contact across the component. This configuration provides maximum contact with the tab and ensures more uniform voltage distribution and better absorption. This enhances the protection potential of the device, allowing it to absorb higher surges and spikes in voltage and current.

The working principle of the V360RA8 series is based on the idea of “clamping”. When an overvoltage event occurs, the clamping action of the 8 tabs creates an effective shield or “capacitor” against high voltage spikes. Once the voltage level exceeds the clamping level of the device, the 8 tabs contact with each other to form an electromagnetic field, momentarily protecting the components from the spike. This simple yet effective protection is especially useful in applications where fast response performance is desired, such as automotive circuits, audio systems, high-performance computing and communication systems, and LED lighting.

In addition to the superior performance, the V360RA8 series also offers a wide range of features. The devices are RoHS compliant and capable of operating over a wide range of temperatures. The series also features an isolation diode which helps to maintain the integrity of the device’s isolation protection. The series is also capable of operating in higher temperature environments, making it suitable for applications in extreme environments. The V360RA8 also offers several options for mounting, including panel mount, SMD and screw mount. These features combine to make the V360RA8 a valuable asset in the TVS-Varistor, MOV market.

The V360RA8 series is an ideal choice for applications where the need for high-efficiency and surge protection is paramount. The unique 8-tab design provides superior performance, and the device’s range of features makes it suitable for use in a variety of scenarios. Robust protection is ensured with the inclusion of an isolation diode, which helps maintain isolation protection over a wide range of temperatures. With its RoHS compliance and ability to mount in different ways, the V360RA8 is a reliable choice for power electronics applications.
