TVS - Varistors, MOVs are from a family of semiconductor devices specially designed to protect electrical circuits from electrical transient that may cause damage to the circuits. ROV05-270K-S is a type of TVS - Varistors, MOVs with a rated current of 270 kA and clamping voltage of 5V. It is mostly used in systems with medium/high voltage applications where a high pulse current is expected.

The device offers a shunt-type configuration for protection. It consists of two electrodes, one connected to the power supply and the other connected to the system or load, so that once the power supply voltage reaches the rated clamping voltage, the device absorbs the excess energy from the overload and safely dissipates it away from the circuit.

The device has a low equivalent series resistance and low leakage current, which makes it suitable for medium/high voltage applications. It also has a very low self-inductance, which allows it to respond quickly to transients. Its high maximum current rating makes it ideal for high power applications, and its wide operating temperature range makes it suitable for high temperature applications.

The device is designed for robust operation and its all-metal construction ensures a long lifetime. It is also ESD and EMI friendly, which means that it can be used in applications that require protection from electrostatic discharge or electromagnetic interference.

The operation of ROV05-270K-S is fairly simple. The device is clamped to the power supply voltage when the voltage reaches the rated clamping voltage, and then absorbs the excess energy from the overload and safely dissipates it away from the circuit. If there is no surge, the device will remain in a quiescent state and not dissipate any energy.

The device is typically used in applications such as motor drives, switch-mode power supplies, solid state relays, AC/DC converters, automotive systems, and lighting systems. In these applications, it helps protect the circuits from damage due to transients or overvoltages.

In summary, ROV05-270K-S is a type of TVS - Varistors, MOVs designed for medium/high voltage applications where a high pulse current is expected. It has a rated current of 270 kA and clamping voltage of 5V, and its all-metal construction ensures a long lifetime. The device is mostly used in motor drives, switch-mode power supplies, solid state relays, automotive systems, and lighting systems to protect the circuits from damage due to transients or overvoltages.
