ROV05-680K-2

The ROV05-680K-2 is a transient voltage suppressor (TVS) designed to protect sensitive electronic equipment from transient overvoltages. It is a non-linear element that functions through a combination of capacitive and resistive elements. It is part of a larger family of transient voltage suppression devices known as varistors, or MOVs (Metal Oxide Varistors).

The ROV05-680K-2 is designed with a high surge current capability and a low maximum clamping voltage. It is rated at 5A surge current and the maximum peak pulse current is 10A. The maximum clamping voltage is 1.4V. The device is constructed from two ceramic plates separated by an oxide layer; during a transient voltage event, the oxide layer breaks down and conducts current, absorbing the surge energy.

In practice, a varistor should always be connected to a protective circuit. The varistor alone cannot dissipate energy; the protective circuit helps it absorb and dissipate the energy as heat. A typical circuit design consists of a varistor, a snubber circuit, and a fuse or thermal cutoff. The snubber circuit is designed to slow down any fast transients, while the fuse or thermal element isolates the varistor from the circuit if the surge current becomes too large.

The varistor can be used in a variety of applications, such as protecting off-line ac/dc converters, dc/dc converters, high-speed microprocessors, input and output lines of communication ports, power supplies, and lighting reprogrammable controllers. The ROV05-680K-2\'s low maximum peak pulse current and maximum clamping voltage make it suitable for protecting devices that require reduced energy absorption and protection from transient voltage.

In summary, the ROV05-680K-2 is an effective solution for protecting sensitive electronic equipment from transient overvoltages. Its low maximum peak pulse current and maximum clamping voltage together with its high surge current capability provide optimal protection in a wide variety of applications. With its excellent durability and reliable performance, it is an ideal choice for protection of equipment from transients.
