Varistors, MOVs are is important components in the electrical and electronic industry. Varistor is a type of semiconductor device which is designed to limit sudden changes as compared to normal operating conditions. It is an acronym for voltage-dependent resistor, and it has two terminals and one linear resistance. It can be used to protect electrical and electronic circuits from sudden transient or voltage spikes.

The V420LU20CPX2855 is a non-linear, bidirectional surge protection technology which acts as a voltage-dependent resistor. It has two electrodes which connect to a pair of cathodes and a control electrode. When a voltage spike is detected, the control electrode senses the spike and then actuates the two electrodes to the their required position. When the spike passes, the electrodes reset themselves to their initial state. As a result the device works as a two way protection for both over-current and over-voltage surge protection.

The V420LU20CPX2855 also provides multiple input and output protection as it can be used for both low and high currents. It is suitable for a wide range of applications such as in automotive, industrial, home appliances, medical, telecommunications, consumer electronics, lighting, military and aerospace, audio/video, and other electronic products. It is typically used for over-voltage and over-current surge protection in TV sets, VCRs, and other consumer electronics.

The working principle of the V420LU20CPX2855 is based on its electro-magnetic field effect. When the device is subjected to a transient voltage or currentexcursion, the electron charge carriers are attracted to the field and form a conductive path which bypasses the resistor. Thiselectron movement temporarily decreases the device\'s impedance and resulting in an increase in current flow. This temporary current increase is used to reduce the transient voltage.

The device also has excellent thermal stability and is capable of withstanding high temperatures and ESD shocks. Moreover, the device is compact in size and easy to install. Thus, it is suitable for applications where space is at a premium and installation convenience is the primary concern.

In conclusion, the V420LU20CPX2855 is an an ideal device for providing both over-voltage and over-current protection in a wide range of applications. It is a reliable and cost-effective surge protection device which has excellent heat stability, is compact in size, and is easy to install. As such, it is the perfect choice for a plethora of applications.
