TVS (transient voltage suppressor) – Varistors, MOVs (Metal Oxide Varistors) are an important device used to protect vulnerable circuits against over-voltage transients. The V385LC40CPX2855 is an example of such a device.

It comprises a series of non-linear zinc oxide (ZnO) discs within an epoxy housing. When the normal DC operating voltage reaches above a predetermined level, the resistance of the ZnO discs drops rapidly, allowing a sudden flow of current. It is as if a series of resistors drop out.

The device provides an effective over-voltage protection since the series of resistors absorb any over-voltage transient energy with their fast switching response. The heat generated during the resulting current is radiated away by the epoxy casing.

The V385LC40CPX2855 is designed for use in a variety of applications and has a number of key features. It has a working voltage of 28V DC and a maximum continuous current rating of 15A. (It is also available in higher current capabilities if required). This makes it useful in industrial (such as automation) and consumer applications ranging from home appliances to car audio systems.

The device features a wide working temperature range (between -40°C and +85°C) and is capable of handling over-voltage transients up to 1000V. It is also resistant to salt mist as well as other environmental pollutants, making it suitable for many outdoor applications. Additionally, the V385LC40CPX2855 complies with UL/IEC60950-1 and GB/T20916.14-2009 safety standards.

In summary, the V385LC40CPX2855 is an effective over-voltage transient protection device suitable for a wide range of applications. It features excellent performance and environmental robustness, making it a reliable protection solution for sensitive electronics.
