TVSs, or transient voltage suppressors, are semiconductor devices designed to rapidly protect electronic circuits from dangerous voltage transients such as electrostatic discharge (ESD). Varistors, meanwhile, are a type of TVSs that suppress overvoltages by providing a low resistance path to ground. MOVs, or metal oxide varistors, act similarly to varistors, but feature a larger capacitance and leverage the nonlinear property of metal oxide layers to provide greater protection from fast transients.

ROV07-181K-S-2 is a varistor specifically designed for lightning surge protection of communication equipments, and is widely used in a variety of high-end communication products. It is an advanced product that has low clamping voltage and excellent surge-resistance characteristics for high-frequency transients. It has a wide operating temperature range (-40°C to +85°C), making it suitable for both indoor and outdoor applications.

The ROV07-181K-S-2 features a Multilayer Varistor (MLV) construction, which provides enhanced protection over the traditional Varistor Disk (VDR). MLVs feature additional layers of metal oxide semiconductors, which increase the transient current carrying capacity of the MOV. By increasing the number of layers, the MLV can absorb higher levels of transients without any leakage current. This makes the MLV particularly suited for use in applications that require high levels of surge protection performance.

The working principle of the ROV07-181K-S-2 can be divided into two steps. First, it detects an overvoltage event through its series-connected resistors and capacitors. Then, it forces the overvoltage current to travel through its nonlinear metal oxide layers. These layers act as a shunt, allowing the varistor to quickly and safely divert the over-voltage to ground. This reduces the voltage across the protected circuit, protecting it from potential damage.

The ROV07-181K-S-2 is primarily designed for shielding various communication equipment such as base stations and routers from transient overvoltages caused by lightning, surges, and ESD. It is also widely used in smart home applications such as data gateways, IP cameras, and access control panels. In addition, it provides protection for industrial control systems based on industrial Ethernet, fieldbus, and RS485-based communication standards. Finally, it can also be used in automotive applications such as Advanced Driver Assistance Systems (ADAS) and electric vehicle charging.

In summary, the ROV07-181K-S-2 is a varistor specifically designed for lightning surge protection of communication equipments. It features a MLV construction that increases the transient current carrying capacity of the MOV. The working principle of the ROV07-181K-S-2 works by detecting an overvoltage event through its series-connected resistors and capacitors, then forcing the overvoltage current to travel through its nonlinear metal oxide layers. It is widely used in a variety of high-end communication products, smart home applications, industrial control systems, and automotive applications.
