The V480LA7PX2855 is one of the most popular models of TVS (transient voltage suppression) Varistors, MOVs (metal oxide varistors). It is used to protect electronic circuits from voltage transients caused by electrical noise, thus making them more reliable, especially in situations where there is a large voltage difference between two different components. A TVS-MOV device provides an ideal solution when dealing with high power transients and is capable of surviving multiple events with minimal stress.

The V480LA7PX2855 operates with a working voltage of 480VDC, becoming conductive when the reverse surge voltage reaches roughly 15-17V. Under normal operating conditions the device is non-conductive until a threshold voltage is reached. At this point, it clamps the voltage below the level of the surge, significantly reducing the potential for damage. The surge current rating is 55A, which ensures that the device can handle extreme transient events. The capacitor value is economically sized as C=450nF which helps to limit surge duration and extend the life of the device.

The V480LA7PX2855 is used in applications ranging from automotive to consumer electronic products. In automotive applications, the device can act as an effective protection against dangerous power surges or vehicle electrical noise. In consumer electronic applications, it serves to protect sensitive components against faulty wiring or interference. Its ability to operate under high temperatures and withstanding pulse power surges is particularly useful in these settings.

Other useful features include its low power dissipation during normal operation and its high peak pulse power capacity. The device is also ultraviolet and moisture resistant. Additional benefits are that the device is relatively compact, allowing for space savings in many designs.

The V480LA7PX2855 is an excellent choice for effective protection against power transients and EMI/RFI noise. This device has become popular in a large number of applications due to its high performance, reliable operation and cost-effective protection
