TVS (transient voltage suppressors), MOVs (metal-oxide varistors) and ROV (radial leaded overvoltage devices) are all components that are used for transient overvoltage protection. In particular, the ROV20E271K-2 is a commonly used ROV component, which is designed to protect sensitive electronic components from overvoltages caused by lightning, electrostatic discharge (ESD) and other electrical transients. This article will discuss the application field and working principle of the ROV20E271K-2.

Application Field: The ROV20E271K-2 is a widely used component in a variety of applications. It is commonly used to protect DC surges in automotive, audio, video, industrial and other electronic products from lightning and ESD. It is also used in solar module junction boxes, telecommunication equipment, video display applications, and smart home/IoT end devices. The device offers a highly stable and consistent performance over a wide temperature range, making it suitable for both indoor and outdoor use.

Working Principle: The ROV20E271K-2 device works in two distinct phases. In the first phase, it will reduce the amplitude of the surge voltage by clamping it down to its clamping voltage level. This will protect the sensitive components from the harmful effects of the transient overvoltage. In the second phase, it will absorb and dissipate the excess energy that has been clamped down by the first phase. This will prevent any further damage to the components and ensure the overall safety of the system.

The ROV20E271K-2 has a relatively low clamping voltage of 26.2V, making it suitable for applications that require lower surge protection. Additionally, the device is rated for up to 2.4J of energy dissipation, which is enough to provide protection against most transients. The device also has a relatively low capacitance of 20pF, meaning it won\'t degrade the performance of the circuit it\'s protecting.

The ROV20E271K-2 is also designed for easy installation and requires no soldering. It has a radial leaded design, meaning it can simply be plugged into a circuit board. This makes it an ideal choice for applications that need to be quickly and easily installed onto a board.

In summary, the ROV20E271K-2 is a wide-ranging component that is suitable for multiple applications. It offers low clamping voltage, high energy dissipation, and low capacitance, making it ideal for protecting sensitive components from transient overvoltages. Additionally, it is easy to install, making it a popular choice for many applications.
