TVS - Varistors, MOVs, are important components for power electronics and electrical engineering. They are used to protect circuits against overvoltage. V660LT50AP is one of the most widely used varistors in industrial field. The V660LT50AP application field and working principle are discussed in this article.

1. Application Field

V660LT50AP is an ideal solution for power output and I/O interface protection from transient over-voltage events. It is suitable for protecting sensitive circuitry from a variety of over-voltage threats including electrostatic discharge (ESD) and dc power surges. This kind of varistor\'s application fields mainly includes automotive, military, space, industrial and medical such areas.

As for automotive application, for instance, The V660LT50AP can be used in automotive fuse protection, battery system protection, power fuse protection, signal line protection, electronic power steering, motor protection, etc.

For military field, V660LT50AP varistor can also be used in surge protection, power fuse protection, ESD protection, ignition protection, RADAR systems and more.

In space, V660LT50AP can be used to protect against transient surges, such as solar flare events and particle bombardment.

In industrial area, V660LT50AP is used to protect equipment from current surges such as those caused by lightning strike or electrostatic discharge. Also it can be used for AC/DC power inputs, secondary inputs, and signal lines in industrial control and safety systems.

Similarly, V660LT50AP can also be found in medical applications, such as protecting medical electronics at patient-connect ports from surges that could lead to equipment malfunction or even cause injury

2. Working Principle

Under normal conditions, V660LT50AP is a non-conductive device. When a surge occurs, it snaps into action and not only diverts the surge current away from the protected equipment, but also absorbs it and safely dissipates it.

During reverse phase operation, the V660LT50AP is an open circuit, meaning that the current divides itself between the short-circuit and the surge protection varistor. The varistor then dissipates the energy created by the surge, while the remainder of the current passes through the protected equipment.

Additionally, V660LT50AP varistors have a current limiting capability. This means that if a surge current threatens to exceed the maximum current allowed, the V660LT50AP will protect the circuit by limiting the peak current to a safe value.

The V660LT50AP is also an exemplary low-voltage drop component. It is capable of dissipating energy without sacrificing the performance of the protected system.

Conclusion

The V660LT50AP varistor has a wide variety of applications in automotive, military, space, industrial and medical fields. It works as an ideal solution for power output and I/O interface protection from transient over-voltage events. It also has a current limiting capability, and is capable of dissipating energy without sacrificing the performance of the protected system.
