TVS - Varistors, MOVs, such as ROV20-911K-S, are two-terminal, non-linear, voltage dependent components often used to protect circuits from transient overvoltage or high-energy electrical pulses. They are commonly used on both the input and output of power supplies. ROV20-911K-S is an ultra-high-peak-power transient voltage suppressor that provides up to 8.5kA of peak protection for high-energy high-frequency pulse applications.

Application fields of ROV20-911K-S

ROV20-911K-S is designed to work in a wide variety of applications including industrial, automotive, military and telecommunications applications. Its use in these various areas, due to its ultra-high-peak power handling, allows it to protect a variety of equipment from damage caused by transient overvoltages. It is often used to provide protection against voltage transients that can damage sensitive electronic equipment or cause it to malfunction. In automotive applications, ROV20-911K-S is usually used to protect the vehicle from voltage spikes that can occur during start-up or shut-down. It can also be used in military and telecommunications applications where it provides a high level of protection from voltage transients.

Working principle of ROV20-911K-S

ROV20-911K-S mainly uses the principle of clamping. Clamping is an instantaneous voltage dependent phenomenon that occurs when an external voltage source is applied to the device. It is essentially the result of a rapid re-distribution of stored charge amongst the device junction layers. When an overvoltage is applied, the device responds with a current flow. This current flow causes the voltage across the device to decrease and stabilize immediately across the junction layers. This act limits the peak pulse current to the junction layers and basically “clamps” it, thus preventing damage.

ROV20-911K-S also features overvoltage protection, which is a process that monitors and limits the peak voltage levels in a circuit. It is essentially a programmable voltage clamp that provides protection from overvoltages. This helps to prevent permanent damage and to preserve the reliability of the circuit. The device limits the peak voltage to a safe level and thus reduces the risk of device failure.

The ROV20-911K-S can provide up to 8.5kA of peak protection for high-energy high-frequency pulse applications. It is designed to offer a wide variety of protection solutions for all kinds of high-voltage, high-energy applications. This device is ideal for use in areas where space is limited and operational environment is high, such as automotive applications.
