TVS devices are well-known components used in a variety of systems for both performance and safety reasons. They are used in power supplies, cable modems, AC adapters and much more. The ROV10-390K-S is an example of a TVS device and it can be used for various applications. In this article, the application field and working principle of the ROV10-390K-S will be discussed.

The ROV10-390K-S is a Varistor, which also known as a Voltage Dependent Resistor (VDR). Varistors or VDRs are non-linear two-terminal electronic components which exhibit a significant variation in their electrical properties when subjected to changes in voltage. In the case of the ROV10-390K-S, it has a breakdown voltage of 390V, a capacitance of 10pF, a dissipation factor of 1ms and a temperature coefficient of -0.08%.

One of the major applications of the ROV10-390K-S is in the protection of electrostatic discharge (ESD) and other transients on data and signal lines. It can be used to protect computers, peripherals, and other sensitive equipment from ESD by clamping the voltage to a safe level before it damages the device. This type of protection also helps to prevent the data corruption which can occur when high voltage spikes are not properly clamped.

The ROV10-390K-S can also be used to protect circuits from overvoltage conditions such as lightning or power surges. It works by attenuating the high voltages before they can cause damage to the device or the circuit. The ROV10-390K-S is also extremely effective at suppressing the electromagnetic interference which can cause unwanted noise interference in circuits.

The ROV10-390K-S uses a unique working principle which utilizes a highly non-linear characteristic to provide protection. When a voltage surge is applied to the device, it will start to conduct at a breakdown voltage of 390V. This will cause the voltage across the device to be clamped at a safe level, which will protect the sensitive components from being damaged.

Once the ROV10-390K-S has attenuated the voltage, it is very important that the device is able to reset itself back to the proper level. This is done by the internal capacitance of the device, which allows for the charge to be dissipated quickly. This ensures that the device does not remain in a conductive state, which can cause additional strain on the circuit.

The ROV10-390K-S is a very versatile device, which has many applications. It can be used to protect components from ESD, overvoltage conditions, and electromagnetic interference, making it an important part of most circuits. By understanding the application field and working principle of the ROV10-390K-S, you can make sure that your circuits are properly protected.
