Transient Voltage Suppressor (TVS) is a protective device that is used in electrical and electronic circuits to limit overvoltage, also known as transient voltage, including both voltage spikes and ESD pulses. It acts by clamping or dissipating the excess voltage by blocking the transient voltages or reducing them to levels that can be safely handled by the protected circuitry. In order for the TVS to be effective, the current that it draws limits the current through the circuit and prevents the circuit from being damaged.

TVS- Varistors, MOVs are two important types of voltage protection devices used in electrical systems. A varistor is a voltage-dependent resistor made of either a network of diodes or of metal oxide semiconductor (MOS) technology. The varistor\'s resistance varies with changes in voltage, and this variation is relatively large. The MOV - Metal Oxide Varistor is a device that not only has a varying electrical resistance, but also has the ability to absorb and dissipate power in response to high voltage spikes, preventing damages to other components.

ROV05H820K-S is a type of TVS- Varistor, MOVs. It is used to protect circuits from voltage transients induced by lightning and other switching transient which can cause damage to electrical components.The rated working voltage of the device is 5.8V with surge current of 2000A (8/20us). It has excellent clamping characteristics and can reduce the effectiveness of overvoltage transients 20 times faster than other devices. The device is independent of temperature and has a resistance of 0.82 ohms in off state. The max leakage current is 0.50mA.The working principle of the ROV05H820K-S is that when a large voltage surge occurs, the resistance of the Varistor changes accordingly and allows a current to flow through it. The current is able to dissipate the energy, avoiding circuit damage. During normal operation, the Varistor process a low impedance, high voltage protection level and keeps the impedance low. This effective combination of low leakage current, fast response time and the highest available surge current makes the ROV05H820K-S an ideal component for voltage surge protection.

ROV05H820K-S most commonly used in electronic devices such as computer, printer, LCD display, power line, communication line, automotive and motor control industry. Its ability to protect against ESD, lightning and other transient events, make it an ideal choice in a number of applications. Specific application fields includes powering and controlling AC motors, motor speed controls, DC-DC supplies, transformers, PLCs, embedded logic, on/off relays and AC control modules.

In conclusion, ROV05H820K-S is an excellent device in TVS-Varistor, MOVs family, it can protect against voltage surges and other transient events. It has a wide range of practical applications, such as powering and controlling AC motors, motor speed controls, DC-DC supplies, transformers, PLCs, embedded logic, on/off relays and AC control modules. The device provides excellent clamping and high current surge protection in a cost effective package.
