V480LS7PX2855

TVS - Varistors, MOVs

Varistors, also known as voltage dependent resistors (VDR) or MOVs (Metal Oxide Varistors), are a kind of electrical component that protects sensitive electronic components from electrical transients. They are specifically designed to “clamp” to the voltage that exceeds preset thresholds. Since they are designed to react to voltage changes in an unpredictable manner, they can be used to protect electronic devices from over current, surges, noise, or voltage spikes.

The V480LS7PX2855 is a Varistor voltage suppression device. It is designed for over-voltage protection of sensitive electronic components and systems. It is a bidirectional device that allows continuous operation between -51V to +68V. Its low-leakage design is suitable for use in microwave ovens, battery backup systems, power converters, and adapters. It has a leakage current of less than 4.5uA at 600V, and a peak clamping voltage of 594V.

The working principle of the V480LS7PX2855 is based on a diode configuration. When the input voltage is above the set clamp level, the zener diode will be forward biased, resulting in a voltage dependent current flowing through the device. The current then will be diverted into the ground current path, thus protecting the device and the circuit against the overvoltage. The device can also be used in reverse polarized applications, in which the zener diode will be reverse biased. The increased reverse leakage current causes the device to shunt the over-voltage current away from other components in the circuit, thereby protecting them from damage.

The applications of the V480LS7PX2855 are varied. It is suitable for over-voltage protection in AC powered equipment, such as TVs, DVDs, audio systems, as well as other consumer electronic devices. It can also be used in the power module applications such as solar converters, LED lights, and inverters. The device can also be used for AC line surge protection and DC line surge protection. Furthermore, it can be used as transient voltage suppression in automotive, medical, and industrial control systems, as well as power supplies and circuit boards.

In conclusion, the V480LS7PX2855 is a reliable Varistor voltage suppression device that provides comprehensive protection for a wide variety of applications. Its low-leakage design and bidirectional functionality make it an excellent choice for over-voltage protection. It is suitable for use in both AC powered and DC powered equipment, and can be used for transient voltage suppression in a variety of circuit boards and industrial applications.
