TVS (Transient Voltage Suppressor) devices are passive electronic components that protect circuits from short duration, high amplitude transients. MOV (Metal Oxide Varistor) is one type of TVS device. MOVs are specific components designed to reduce the voltage that is applied to a circuit while allowing the current to flow through the circuit. ROV20H22K-2 is a type of MOV. The device is mainly used to protect circuits from excessive voltage spikes, current pulses, electrostatic discharges, radio-frequency interruptions and lightning.

Applications of ROV20H221K-2

The ROV20H22K-2 is designed to be used in various applications that require protection from transient voltage or current spikes. This device is ideal for use in several industrial, computer, communication, and consumer electronics applications. It can also be used in data line protection. This device can be used to protect power supply rail lines, computer based systems, telecommunications line cards, and specific commercial and industrial applications.

Working Principle of ROV20H221K-2

The ROV20H22K-2 is a specific type of MOV (Metal Oxide Varistor) device that combines the principles of a power and a voltage regulator. It utilizes a non-linear resistor element made of zinc oxide which is connected between two terminals, the anode and the gate. When an external voltage is applied across these two active elements, a dissipative voltage-dependent capacitor is formed. This resulting voltage is dependent on the change of the two capacitance values: the total capacitance of the device and the capacitance of the resistor. When an overvoltage is applied across the device, the resistor element begins to absorb the excess energy and convert it into heat.

The device has overvoltage protection that triggers at a specific voltage level, and reduces the voltage to a safe level. The device is also capable of protecting internal circuit elements from electrical transients. The device is designed to limit any voltage pulse applied to it to a specified level. It also limits the start and maximum operating voltage. It has a fast response time that prevents possible damage to the internal circuit components and reliably protects from over-voltage spikes.

The ROV20H22K-2 is a popular device among manufacturers due to its high performance, speed, and reliability. It is also versatile and easy to implement, making it an ideal protection option for many applications.
