TVS varistors, MOVs (metal oxide varistors) are components used in electronic circuits to protect against transient voltage spikes, such as those caused by inductive kick or large pulses. They can also be used to limit inrush current in DC/DC converters, AC/DC converters and switching power supplies. The ROV05-470K-2 is one such device and has a wide range of applications.

The ROV05-470K-2 varistor is a two-terminal, surface-mount varistor in a TO-252 package. It is available in a variety of voltage ratings and is designed to provide protection from high voltage spikes. The device features an internal ESD (electrostatic discharge) protection diode, which prevents devices connected to it from being damaged by an over-voltage event.

The ROV05-470K-2 provides a wide operating temperature range from -40°C to +70°C, making it suitable for use in a wide variety of applications. The varistor has a minimum breakdown voltage of 340V and a maximum working voltage of 470V. The maximum peak current is limited to 5.6A, while the surge current rating is limited to 8.35A. Additionally, the device has an insulation resistance of >100MΩ, which ensures that it can operate safely in high-voltage applications.

The working principle of the ROV05-470K-2 is based on a two-terminal metal oxide varistor. The two terminals consist of two plates, one of which is made of a metal oxide material and the other of a zinc oxide material. When a transient voltage spike occurs between the two plates, the two materials form a varistor, which acts like a diode and limits the voltage spike.

The ROV05-470K-2 is ideal for a variety of applications, including AC/DC and DC/DC converters, solenoid drivers, battery chargers, LED lighting, audio power amplifiers, and many more. The device is capable of providing protection against over-voltage events, preventing damage to connected components or devices. It is also suitable for use in automotive applications, as it meets automotive grade standards.

The ROV05-470K-2 is an ideal device for a variety of applications and provides reliable protection against transient voltage spikes. Its wide operating temperature range and low leakage current make it suitable for use in a variety of applications, including automotive, AC/DC and DC/DC converters, LED lighting, and more.
