TVS (Transient Voltage Suppressors) and MOVs (Metal Oxide Varistors) are protective devices that are designed to limit the amplitude of voltage fluctuations in AC and DC lines. MOVs are one type of TVS, and ROV07-390K-2 is an example of a low-capacitance MOV device. In this article, we will explore the application fields and working principles of ROV07-390K-2.

ROV07-390K-2 Application Fields

ROV07-390K-2 can be used in a variety of industrial and commercial applications, including power supplies, isolated DC/DC converters, high-speed data lines, and telecom circuits. It is especially well-suited for circuits that experience frequent voltage spikes or surges, such as those found in automotive systems, lighting control systems, and other high-voltage, low-current applications.

ROV07-390K-2 has a peak pulse power of up to 390 kW, making it suitable for use in high-energy circuits. Its maximum operating voltage is 25 volts, allowing it to handle relatively low current applications. It also has a low leakage current (less than 10 A) and fast response time (typically less than 1 microsecond).

ROV07-390K-2 Working Principle

ROV07-390K-2 is a metal oxide varistor (MOV) device. This type of device uses a special semiconductor material to change its resistance in response to changes in voltage. When a voltage spike exceeds the MOV\'s rated peak power, current flows through the device and is diverted away from the circuit. This reduces the size of the voltage spike, preventing damage to the circuit and its components.

MOVs are typically constructed from a disk of zinc oxide in a ceramic matrix. When the voltage exceeds the device\'s rating, the electrons move quickly through the material, changing its resistance. This changes the current in the device, and the diverted current helps dissipate the voltage spike.

MOVs are usually used in conjunction with other protective devices, such as surge arresters, fuses, and over-voltage protection circuits. Together, these devices provide multiple layers of protection that ensure the proper operation of a circuit or system.

Conclusion

ROV07-390K-2 is a low-capacitance MOV device that can be used to protect circuits from voltage spikes and surges. It has a peak power of up to 390 kW and a maximum operating voltage of 25 volts, allowing it to handle relatively low current applications. Its low leakage current and fast response time make it well-suited for use in a variety of industrial and commercial applications. When used in conjunction with other protective devices, ROV07-390K-2 can provide an effective layer of protection against voltage spikes and surges.
