TVS - Varistors, MOVs

V480LU80BPX2855 is a voltage sensitive device used in a variety of application fields. It’s a member of voltage dependent resistor (VDR), also called as voltage clamping TVS, which has the property of clamping the voltage according to its designed breakdown voltage.

V480LU80BPX2855 is designed to manage and protect sensitive electrical components from surge and transient voltage spikes. It is widely used in applications such as power supply, automotive, cellular phone and general-purpose electronics.

Application Field

V480LU80BPX2855 is designed for low energy and medium energy transient application. The varistor can limit the surge energy to a specific level and provide protection for both the equipment and the environment. It is designed to protect low voltage equipment, such as data lines in the communication networking, automobile circuits, and AC/DC switching power supplies.

It can also be used in other applications where high energy arresters are not appropriate. The high capacitance technology also helps to reduce the EMI interference.

Working Principle

V480LU80BPX2855 is a voltage-dependent resistor or varistor. The operation of this component is based on the principle of voltage sensitive conduction. The part acts as an impedance or resistance that changes its value depending on the magnitude of the applied voltage. The resistance of the device is very high at lower voltages and reduces as the voltage increases.

When the applied voltage exceeds the rated voltage of the device, its resistance decreases, causing it to conduct more current and clamp the voltage. This effectively limits the surge energy to a specific level and provides protection for both the equipment and the environment.

V480LU80BPX2855 also has high capacitance technology, which helps to reduce the EMI interference.

Conclusion

V480LU80BPX2855 is an application specific device designed for low energy and medium energy transient application. It provides protection from overvoltage, overcurrent, and EMI interference and is suitable for use in data lines, automotive circuits and AC/DC switching power supplies. The working principle of this varistor is based on the principle of voltage sensitive conduction.
