Introduction

TVS - Varistors, MOVs are popular for protecting electronic equipment from the hazards of high voltage, such as lightning, electrostatic discharge, and other environmental influences. One such device widely used for this purpose is the V175LS20APX2855. This component offers a high level of safety when it’s properly installed and used.

Application Field

The V175LS20APX2855 is mainly used for protection against transient overvoltage and related surges. It provides protection from overvoltages of up to 40V with a clamping voltage of 28V.It’s designed for use in applications ranging from general-purpose data lines and telecom lines to industrial, automotive, and consumer applications. It’s suitable for use in applications such as power supplies, telecom lines, automotive electronics, or any other system that needs protection from overvoltage.

Working Principle

The V175LS20APX2855 is a voltage-dependent resistor that consists of metal oxide varistor material. This material is made up of particles of zinc oxide mixed with small amounts of bismuth and other metals to produce a unique resistance-voltage response. When an overvoltage is applied, the device acts like a variable resistor. The resistance decreases as the applied voltage increases. This means that the device can effectively absorb the overvoltage and thus protect the system from voltage spikes and other transients. When the voltage is within the normal range, the device acts like an open circuit. This allows the current to flow freely without any disruption.The V175LS20APX2855 also features an electrostatic discharge (ESD) protection circuit. This helps to protect against high-energy static discharges. This is especially important in applications where static electricity can cause damage to sensitive components.

Conclusion

The V175LS20APX2855 is a highly effective device for protecting sensitive electronics from overvoltage and electrostatic discharge. It offers many benefits for various types of applications, from telecom lines to automotive electronics. Its high clamping voltage of 28V and ESD circuitry ensures a high level of safety when properly used and installed.
