ROV05H221K-S-2 application field and working principle

ROV05H221K-S-2 (hereinafter referred to as "TVS") is a kind of circuit protection device, widely used in vehicles, equipment, and electrical and electronic systems. It belongs to the category of TVS - Varistors, MOVs.

TVS is based on a silicon diode between line and ground to create a series voltage clamp for overvoltage protection. Its main function is to reduce over-voltage problems, providing an additional level of protection for devices and sensitive components.

TVS is designed to shunt and overwrite voltage spikes, such as waves, transients and ESDs. It not only helps protect systems, especially sensitive electronic components, from excessive voltage, but also helps safeguard against other potential problems caused by over-voltage, such as noise or long duration damage.

TVS is an important component in system protection, and it needs to be selected carefully according to the voltage form, surge current strength and pulse width in the system to be protected. The surge current through the transient voltage suppressor depends on the external circuit configuration. When the third electrostatic discharge (ESD, CDM, etc.) or transient pulse is applied to the system, the TVS will clamp the voltage and clamp the current.

TVS takes advantage of avalanche breakdown characteristics of high-voltage pn junctions, which can effectively suppress inrush current without causing continuous conduction. During the transient state, the avalanche breakdown is used to release the over-voltage energy to the ground, thus protecting the corresponding device.

Moreover, the reverse breakdown voltage for ROV05H221K-S-2 is rated at 5.3V. It offers a lower working voltage than many other products, making it suitable for a range of applications such as12V power systems and AC/DC connectors. It also provides excellent ESD protection with low clamping voltages. The TVS also features high surge current capabilities with a maximum clamping voltage of 22V.

As one of the most widely used protection components, the ROV05H221K-S-2 is widely used in automotive systems, mobile devices, and power supplies. It is also a useful tool to protect industrial control systems, power systems, telecommunication networks, LED lighting systems, and other applications.

In conclusion, ROV05H221K-S-2 provides an extra layer of protection for sensitive components, reduces the vulnerability of devices to over-voltages, and is suitable for a wide range of applications. Its lower working voltage and higher surge current capabilities makes it a reliable and effective option for application.
