TVS (Transient Voltage Suppressor) devices, like the ROV05-181K-S, offer many benefits to solid-state electronics, from protection against voltage spikes or surges in circuits, to providing protection against thermal runaway. A combination of a diode and resistor, these devices are known as Varistors and MOVs (Metal Oxide Varistors and MOSFET Varistors).

The ROV05-181K-S application field is an UL 1449 approved device and is designed to provide overvoltage protection of audio, video, and data lines in office equipment, telecom and broadcast equipment, game console systems, home and automotive audio/video systems, and similar consumer digital equipment. This device is also used to provide Class I surge performance in applications where high current spikes occur.

The working principle of the ROV05-181K-S is fairly straightforward. When a surge or spike of voltage higher than the standard operating voltage of the device, flows through a circuit, the ROV05-181K-S operates as a miniature surge arrester, diverting the excess energy into the device, safely limiting the operating voltage of the equipment. This process is very similar to how a traditional surge protector operates, except in the case of Varistors and MOVs, the voltage limit is significantly lower, meaning they can protect against smaller spikes more effectively.

ROV05-181K-S Varistors and MOVs also have a clamping voltage of 100V (standoff voltage) (1.4V to 181K minimum), with a clamping voltage of 180V (1.4V to 181K minimum). The device is contained in an epoxy case, suitable for use in an enclosed assembly or device, and has an operating temperature range from -40°C to +175°C.

Varistors and MOVs, like the ROV05-181K-S offer protection for equipment such as computers, cell phones, and other sensitive electronics, against electrostatic discharge, surges, and spikes in voltage. This helps to keep sensitive components safe and protected, ensuring they operate properly over time. In addition to this, these Varistors and MOVs can also be used to provide protection in high current applications, such as those encountered in the automotive and aerospace industries.

In conclusion, Varistors and MOVs, such as the ROV05-181K-S help protect sensitive electronics from damaging high voltage events and thermal runaway. With an operating temperature range of -40°C to +175°C and a clamping voltage of 180V, the ROV05-181K-S provides a reliable and cost effective solution for both consumer and industrial applications.
