V480LC80CP application field and working principle

Varistors, or voltage dependent resistors, MOVs and other surface mount components are used as transient voltage suppression (TVS) in a variety of devices ranging from telecommunication to consumer electronics. A variety of varistors, such as the V480LC80CP, offer distinct advantages in a variety of applications.

The V480LC8080CP is a surface-mount peak pulse suppression device (TVS). It utilizes advanced, patented, silicon chip technology and a chokeless highly enhanced ARC-resistant design to create an effective transient protection solution. The device is supplied in an 8-pin surface-mount package where two of the pins are loading pins.

V480LC80CP Applications

The V480LC80CP is suitable for Transient Voltage Surge Suppression (TVSS) and other transient voltage protection applications in consumer electronics, industrial control systems, telecommunications systems, network equipment, and power systems.

This device is designed to provide reliable over-voltage protection from lightning strikes, and other electrical transient events, in most circuit environments. It can be used in many areas, such as automotive, telecom, power industry, medical, and test & measurement.

V480LC80CP Working Principle

The V480LC80CP uses a surge protection technology known as Metal Oxide Varistor (MOV). A MOVs component is a nonlinear, solid state resistor whose resistance decreases significantly with increasing voltage. This characteristic enables it to absorb or clamp electrical surges and protect the device it is connected to.

The V480LC80CP is fitted with MOVs chips that can withstand pulse power of up to 8kV and clamping voltage of up to 48V. Its high surge capability ensures that it can handle transient voltage levels when connected to 8/20 us waveforms.

When a transient voltage strikes the V480LC80CP, the voltage across its terminals increases, activating the nonlinear nature of the MOVs chips. The MOVs chips absorb the energy of the transient voltage, while limiting the resultant voltage across the terminals. This limits the amount of damage that the transient can do to the connected device.

The V480LC80CP is not only effective at absorbing or clamping transient voltage, but it is also highly resistant to ARC erosion, which is caused by the excessive energy generated by high-voltage current. As the energy of the ARC draws the MOVs chips to life, its nonlinear nature allows it to dissipate the energy into the surrounding environment.

Additionally, the V480LC80CP is designed with enhanced diffused silicon technology that prevents the voltage from entering the device for too long. This protects the connected circuit from sustaining too much damage.

Conclusion

The V480LC80CP is an advanced surface-mount peak pulse suppression device (TVS). It utilizes advanced, patented, silicon chip technology and a chokeless highly enhanced ARC-resistant design to provide effective protection against transient voltage events. The V480LC80CP is suitable for a wide range of applications, and is especially effective at providing over-voltage protection from lightning strikes, and other electrical transient events. It also offers superior resistance to ARC erosion.
