ROV05-820K is one type of TVS - Varistors, MOVs. It is one kind of two voltage sensitive components for ESD protection, applied in different applications for surge suppression. It is important to understand the working principle of ROV05-820K and its application field before you decide to use the device in your project.ROV05-820K is a voltage-dependent resistor (VDR), also known as Voltage Dependent Resistor (VDR). It contains a zener diode connected to a capacitor with passivation. The combination of these components provides an effective protection circuit against transient voltage surges and transients. Its main characteristic is that when the voltage across the device exceeds a certain threshold, the internal diode begins to conduct, directing current to the capacitors, thus clamping the transient voltage surge.The typical application field of ROV05-820K is mainly used in systems and equipment that need to protect against ESD, EFT and other surge events. Typical application areas include computers, networking equipment, telecommunications equipment, automobiles, medical systems, consumer electronics and industrial control systems.The working principle of ROV05-820K is relatively straightforward. The device starts to conduct current when a transient voltage surge is detected. The device then places a resistor and capacitor in series, allowing current to flow from the external power source to the capacitor. The capacitor helps to reduce the voltage spike and the resistor helps to limit the total current delivered to the capacitor. This helps to protect the device from the voltage surge and reduce the risk of damage from the transient voltage transients. Due to its unique design, ROV05-820K offers a wide range of protection characteristics. It can be used to protect circuits from ESD and EFT surges with a wide variety of voltage thresholds and pulse rise times. It also offers excellent protection against lightning strikes and line transients.ROV05-820K is a reliable, cost-effective solution for providing ESD and EFT protection in systems. Its simple design and simple implementation makes it an ideal choice for a wide range of applications. It is also relatively low cost compared to other surge protection devices.In conclusion, ROV05-820K is a voltage-dependent resistor (VDR) that provide reliable protection from ESD and EFT surges at a cost-effective price. Its simple design and simple implementation makes it an ideal choice for a wide range of applications, such as computers, automotive systems, consumer electronics, medical systems, telecommunications equipment, industrial control systems and more.
