TVS - Varistors, MOVs

TVS or transient voltage surge suppressors are used mainly for over voltage protection in general circuits. These devices are usually composed of varistors (Metal Oxide Varistors, MOVs) which are very efficient at absorbing transient voltage pulses and surge currents.V460LU7PX2855 is one of these surge suppressors and is designed to protect circuits from transient voltage surges. It is commonly used in many applications, such as in voltage sensitive components, power supplies, data buses and automotive applications.

Working Principle

V460LU7PX2855 is a varistor which works by using the metal-oxide semiconductor process. This process involves the formation of a thin layer of metal oxide between two electrodes. The metal oxide layer acts as an insulator when no voltage is applied, but allows current to flow when a voltage is applied. That is why they are also often referred to as Voltage Dependant Resistor (VDR).When a voltage transient (fast rise time and short duration) occurs, the metal oxide layer is subjected to rapid expansion and contraction which allows high current to flow through it and absorb the energy of the transient. This often keeps components from being harmed due to excessive voltage levels.

Application Field

Due to its good transient response, V460LU7PX2855 is used in many applications including automotive, military, consumer electronics, medical equipment, telecommunications, data communications and power supplies.In automotive applications, V460LU7PX2855 is often used to protect components from power supply fluctuations and voltage spikes caused by ignition coils. In consumer electronics, it is used to protect components from electrical interference and power spikes caused by lightning.In addition, V460LU7PX2855 can also be used in telecommunications, data communications and power supplies to protect circuits from excessive voltage induced by lightning and surges. It is also often used in military applications to protect mission-critical components.

Conclusion

V460LU7PX2855 is an effective transient voltage surge suppressor which is used in many applications. It is composed of varistors, which are metal oxide semiconductor devices that are very effective at absorbing transient voltage pulses and surge currents. Its application field includes automotive, military, consumer electronics, medical equipment, telecommunications, data communications and power supplies. Its working principle relies on the metal oxide semiconductor process which allows high current to flow through and absorb the energy of transients and prevent components from being harmed.
