ROV07H221K-2

TVS (Transient Voltage Suppressors) poles and MOV (Metal Oxide Varistor) poles are two distinct types of electronic components used in electric circuit boards. ROV07H221K-2 is a TVS-MOV combination which combines the capabilities of both devices in one package. It offers exceptional suppressor performance for overvoltage protection against transients, as well as an integrated MOV (Metal Oxide Varistor) for performance enhancement in surge and ESD (Electrostatic Discharge) protection.

The ROV07H221K-2 is an effective and smart solution for overvoltage or ESD protection applications in which a single part can provide both superior protection performance and high power gain. It is ideal for use in home appliances, communication devices, medical equipment, automotive electronics, and industrial machines, as well as many other commercial and consumer applications.

Application Fields

ROV07H221K-2 TVS-MOV combination is suitable for overvoltage and ESD protection applications. It is suitable for use in electronic circuits, particularly those circuits that are used in electrical & electronics consumer products such as home appliances, mobile phones, and industrial machines, as well as automotive electronics. This device is also suitable for use in medical equipment, such as defibrillators, respirators, and X-ray machines. It is also applicable in industrial control systems such as PLCs and HMIs.

Working Principle

The ROV07H221K-2 working principle is based on a unique combination of TVS (Transient Voltage Suppression) and MOV (Metal Oxide Varistor) capabilities. The TVS section protects the circuit from overvoltage transients, while the MOV section provides performance enhancement and prevents further voltage damage. The ROV07H221K-2 has an ESD protection rating of 14kV, and its transient voltage suppression capability has a tested peak pulse power rating of 400 watts. The total clamping voltage is 6.8V.

The TVS section works by clamping the voltage instantly and limiting the current to a safe level. The TVS section also acts as a voltage divider, allowing the MOV section to act effectively by absorbing the excess current within the circuit. The MOV section helps to reduce damage caused by surges, and also prevents further voltage build up in the circuit. The ROV07H221K-2 has a fast response time of less than 1ns, allowing it to react quickly to overvoltage and ESD issues.

The ROV07H221K-2 is a power efficient device that ensures the circuit is constantly protected from transient voltage, ESD, and surges. It is designed with robust protection features that ensure the circuit does not become damaged in the event of a power surge or ESD occurrence. This device also offers excellent value for money with a low purchase cost and high reliability.
