TVSs (Transient Voltage Suppressors) are MOVs (Metal Oxide Varistors) which are used to protect sensitive electronic components against ovdervoltages. The V140LA5PX1347 is one such device which can be used in commercial, industrial and residential applications. It is an cost effective, reliable and easy to install suppressor, ideal for transient voltage protection. In this article, we will look at the application field and working principle of the V140LA5PX1347.

Application Field

The V140LA5PX1347 is a versatile device that can be used for a variety of applications. It offers reliable protection against transient voltage imposed on sensitive electronic components in industrial, commercial and residential environments. It can handle large levels of surge voltage without damage, and is fast to react to surges. The device is suitable for a wide range of processes, from simple motor switching to complex microprocessor-based industrial control systems.

In particular, it is suitable for protecting digital logic circuits against transiences on I/O ports, and can also be used to provide protection against spikes caused by external sources such as lightning. Additionally, it is ideal for protecting power supplies, such as those found in cell phone chargers and other consumer electronics.

Working Principle

The V140LA5PX1347 is a non-directional MOV (Metal Oxide Varistor), which works based on its electrical characteristics. The device is constructed out of a surface-mounted ceramic package which contains two conductive electrodes. The electrodes are interconnected via a semiconductor material which exhibits a non-linear resistance in response to an applied voltage.

When there is no applied voltage, the resistor remains in a high-resistance state, and the current flow is directed away from the terminals of the device. However, once a certain threshold voltage is passed, the resistor changes state and the current can flow freely from one terminal to other. This allows for a surge or transient voltage to be clamped to an acceptable level.

The device also features a noise filter in order to suppress any interference caused by the transients. Furthermore, the ceramic package ensures that the device is resistant to degradation from external environmental factors such as temperature changes.

Conclusion

The V140LA5PX1347 is an ideal choice for transient voltage protection in commercial, industrial and residential environments. It is an cost effective, reliable and easy to install device which offers fast and reliable protection against transient voltage imposed on sensitive electronic components. Its non-directional MOV technology ensures effective suppression of voltage spikes, while the noise filter and ceramic package aid in protecting against interference and environmental influences.
