V130LU2

Varistors, also known as Voltage Dependent Resistors (VDRs), are components that act as a high-impedance circuit when the applied voltage is below a certain threshold, and as a low-impedance circuit when the voltage is above the threshold. This enables them to be used as transient voltage suppressor (TVS) devices in electrical circuits, which helps protect sensitive components from damagingVOLTAGE spikes.The Littelfuse V130LU2 is a Metal Oxide Varistor (MOV) designed to help protect circuits from transient voltage surges.

V130LU2 Application Field

The V130LU2 is mainly used to protect electronics from momentary voltage spikes, or transient voltages, which can occur in an AC circuit due to lightning, motor switching, and other events. This device can help protect lines, equipment, or entire systems from damage, depending on the magnitude of the over-voltage or under-voltage. Common application areas include: Automotive systems, industrial equipment, consumer electronics, telecommunications equipment, and other applications which may be subjected to transient voltage surges.

V130LU2 Working Principle

The V130LU2 is a varistor, based on a metal oxide semiconductor. When the voltage applied to the device is below a certain threshold, it acts as a high-impedance circuit, by not allowing any current to flow. When the voltage rises above the threshold, the device acts as a low-impedance circuit, and it will start to conduct a large amount of current, thereby dissipating the excess energy and clamps the voltage to a safe level. The device has a clamping voltage range(Vc) of 11V to 50V. With the addition of a transient voltage suppressor diode and a resistor, varistors can be used to protect any circuit from voltage transients

Conclusion

The Littelfuse V130LU2 is a versatile metal oxide varistor designed to help protect circuits from transient voltage surges. It can be used in a variety of applications from automotive systems to consumer electronics. The device works by acting as a high-impedance circuit below a certain voltage threshold, and as a low-impedance circuit above the threshold, allowing it to clamp the voltage to a safe level and dissipate excess energy. Combined with a transient voltage suppressor diode and a resistor, the V130LU2 can help protect components from damaging voltage spikes.
