TVS - Varistors, MOVs are voltage-dependent devices used for protection in various applications. The ROV20E201K-2 is a common device in this category due to its high tolerance to thermal and mechanical shocks, as well as its low capacitance. The ROV20E201K-2 device has an operating temperature range of -55°C to +150°C, an leakage current of 0.2mA max at 90VAC, and a capacitance of 0.2pF max at 1MHz.

The ROV20E201K-2 was developed for use in sensitive electronic applications. The device incorporates a high peak power voltage degradation mechanism which provides superior surge and transient protection as compared to standard varistors. The device also has an arc less positive characteristics and does not contain PTC elements. As a result, lower power surges are not cut off and due to the low capacitance, faster switching is achieved.

The working principle of the ROV20E201K-2 is based on its construction. It utilizes a stack of PTC elements, metal oxide layers, and a dielectric layer in order to form a voltage-dependent device. The dielectric layer provides a large capacitance value at low applied voltages, while the PTC elements allow for a dynamic resistance shift due to temperature or applied voltage changes. This variable resistance in combination with the dielectric capacitance gives the ROV20E201K-2 its wide voltage range, high peak power handling capabilities, and low capacitance values.

The ROV20E201K-2 is ideal for protection from overvoltage surges in a variety of applications. It can be used in automotive, consumer electronics, and industrial applications. In automotive applications, it can provide protection from transient surges caused by engine noise, ignition sources, and alternator diodes. It can also provide protection to consumer electronics such as DSL modems, LCD televisions, and video game consoles. In industrial applications, the ROV20E201K-2 can provide protection against transients caused by ESD, lighting, or similarly generated sources.

The ROV20E201K-2 is also well suited for use in solar tracking and high voltage environments due to its thermal and mechanical shock tolerance and low capacitance. The device is able to withstand temperatures up to +150°C and is also resistant to mechanical shocks and vibrations in excess of 25G. Additionally, its low capacitance makes it suitable for use in high voltage environments where overvoltage protection is required.

In conclusion, the ROV20E201K-2 is a versatile device and is an ideal choice for high power surge and transient protection. Its low profile, thermal and mechanical shock tolerance, and low capacitance make it well-suited for a variety of applications. In addition, its peak power voltage degradation feature and wide range of operating temperatures make it a reliable protection device for sensitive electronic systems.
