TVS - Varistors, MOVs are widely used in manufacturing, engineering industry as they offer protection to electronic systems from various forms of transients and damages. The V5.5MLA0805H is a popular varistor model amongst engineers and technicians and is used as a surge protector.

The V5.5MLA0805H is a multilayer integrated circuit (MLIC) that can be used to protect sensitive electronic equipment against overvoltages and undershoot transients. It is mainly used in a wide range of applications such as cell phones, telecom device, automotive, industrial, automotive accessories, and various other computers. The V5.5MLA0805H has a five layer design that incorporates two two-terminal varactor chips and three resistors which help to control the clamping voltage.

The V5.5MLA0805H is designed to protect against a surge voltage of over 55.5V peak. The maximum voltage a varistor can absorb is typically related to its size, and the larger models take up to 130V peak. The varistor has a desirable fast response time, so when the voltage reaches its clamping voltage, the spike is dissipated quickly and the device is ready to absorb the next surge. This kind of high-efficiency varistor also helps to minimize the probability of a surge occurring in the first place.

The working principle behind the V5.5MLA0805H is that the varistor changes its resistance value for different input voltages. When the input voltage rises above its clamping voltage, the varistor\'s resistance drops. As the voltage increases, the resistance of the varistor decreases, thereby allowing current to pass through the device. This increases the output voltage of the device and helps to protect other components connected to it.

The V5.5MLA0805H is especially ideal for protecting sensitive electronic equipment from overvoltages, undershoots, and other forms of transients such as electrostatic discharge (ESD). This device is also suitable for use in automotive and industrial applications. As this device is resistant to high temperatures, it is also suitable for use in environments with high temperature and humidity.

The V5.5MLA0805H is a cost-effective and reliable solution for protecting sensitive electronic equipment. It is designed to provide protection from transient voltage surges and undershoots, and is suitable for use in a wide range of industrial and automotive applications. With its fast response time and low voltage leakage, this varistor effectively protects various types of equipment from damage caused by overvoltages and transients.
