TVS - Varistors, MOVs, are commonly used in the sensitive electronic environment to protect against transient overvoltage. Among them, V480LT80CP is an important component that can provide reliable overvoltage protection in a wide voltage range. In this article, we will introduce its application field and working principle.

Application Field

V480LT80CP is a very popular Transient Voltage Suppressor (TVS) with an exceedingly fast response in a surge protection circuit. It is mainly used to protect voltage sensitive devices, such as microcontrollers, opto-electronic components, power supply boards, and USB protection systems, from unpredictable or severe transient overvoltage. It can also be used in consumer electronic products such as television, computer and various appliances.

Working Principle

When a voltage greater than it’s peak surge current rating is applied, V480LT80CP opens up a path for the current to flow. This causes the voltage to drop across the device and shuts off the surge on the device. This way the V480LT80CP ensures that transient overvoltage is eliminated and the connected electronics and other components are protected. In this way, V480LT80CP can serve as a lightning, overvoltage, and electrostatic discharge (ESD) protection device.

V480LT80CP is composed of a metal oxide varistor (MOV) encased in a plastic casing. The MOV is sensitive to the current passing through it and when the overvoltage occurs, it will instantaneously reduce the current passing through it and generates a large negative voltage for protection. When the voltage comes back to regular levels, the MOV goes back to its non-conductive state.

V480LT80CP is relatively small in size, and comes in both automotive and SMD package types, making it more versatile. It also has a wide operating temperature range, from -40°C to 125°C, which makes it suitable for a variety of applications. It has a peak surge current of 5.8A with a clamping voltage of 80V. And it has excellent surge capability and high reliability.

Conclusion

In conclusion, V480LT80CP has a wide application range and superior overvoltage protection ability. It is particularly suitable for protecting voltage sensitive electronic devices, and can also be used in appliances, plant automation and factory automation. Thanks to its small size, wide operating temperature range and high surge capability, V480LT80CP is indeed an essential component for various electronic device protection.
