Transient voltage suppressors (TVSs) are active components which protect electrical circuits from others transient events, most notably electro-static discharge (ESD). TVSs are made upon diode technology with or without avalanche diode (AV); the latter being less sensitive to environmental parameters which highly improves their robustness. TVSs have existed for decades now, from simple rectifying voltage protectors to highly integrated ESD networks spreading all over printed circuit boards (PCBs). TVSs are usually classified according to their functionality, either as varistors, MOVs or TransZorbs.

ROV07-101K-S is one of the most popular components of TVSs. It is a bi-directional transient voltage suppressor with a breakdown voltage rated at 8.2V (Vbrm=8.2V) and is designed to protect up to 5.5 Volts (VRMS=5.5V) applications. The transient current is rated at 10A and the clamping voltage is rated at 16V (VC=16V). Its working range encompasses operational temperature ranging between -55° and 150° Celsius for industrial applications.

ROV07-101K-S belongs to the family of the Varistors, and the name corresponds to MOV - Varistor. It is a specialized form of the ZnO (Zinc Oxide) type Varistors and is also well-known as a MOV –Metal Oxide Varistor. Comparing with other Varistor types, ROV07-101K-S is known as low voltage transientVaristor. It is a bi-directional component for low, medium, and high-voltage transient suppression applications.

The main advantage of the ROV07-101K-S is its bidirectional functionality, which ensures that no matter whether the transient voltage is positive or negative, it can be clamped. Its encapsulation ensures robustness and immunity to environmental parameters such as humidity and vibration, making them ideal for industrial applications. Additionally, the ROV07-101K-S is packaged with leads that make a single, integrated assembly, which helps in reducing overall cost in installation.

The working principle of ROV07-101K-S is based on the principle of Zinc Oxide varistor. When the transients come, the Zinc Oxide particles in the Varistor become electrically conductive and destabilize the region of transition between the N-Type and P-Type materials. This creates a low impedance path from anode to the cathode of the Varistor, which short-circuits the supply voltage and protects the device or circuit from the over-voltage transient. In this way, the ROV07-101K-S acts as a surge protector and can protect the connected electrical devices from over-voltage transients.

ROV07-101K-S is a perfect choice for applications that look for robustness, immunity to environmental parameters, high surge ability, low clamping voltage, cost-effectiveness, as well as bidirectional protection. Its Varistor properties enable it to address a wide-range of over-voltage protection problems, from industrial, automotive to telecommunication applications.
