TVS (Transient Voltage Suppressors), Varistors and MOVs are common types of electronic components, typically used to reduce damage to electrical appliances, circuits, and other related systems due to sudden electrical spikes, power surges or ESD (electrostatic discharge) events. Varistors, in particular, are solid-state components made of an alloy of metals with a variable resistive feature based on the material’s voltage, temperature and frequency parameters. Varistors are also useful for protecting equipment from lightning and power line surges.

The V625LT40APX2855 is a metal oxide varistor from Vishay which provides superior circuit protection from transient voltage events such as surges and spikes. This metal oxide varistor is an effective over-voltage protection devicerecommended for use in a variety of applications. Its primary function is to protect dc power supplies, processors, and other sensitive electronic components from voltage surges and spikes. It provides a capacitance value between 61pF and 245pF and its voltage rating range is 5V AC to 28V AC.

The V625LT40APX2855 is highly reliable and has a highly stable temperature coefficient which provides excellent transient voltage protection and reliability. It is a single piezoresistor constructedfrom a series of layers of different materials and has a robust casing which protects its components. It also has an extremely fast response time which helps to minimize transient voltage damage.

The V625LT40APX2855 is suitable for a wide range of applications such as power supply lines, data lines, and consumer appliance circuit protection. It can be used as an AC power line protection device and as an overvoltage/undervoltage protection device. It can also provide effective protection against ESD events. In addition, the varistor can be used for overvoltage and over-current protection in automotive electronics, telecommunication equipment, aerospace, industrial control, and medical equipment.

The V625LT40APX2855’s working principle is based on the thermodynamic properties of the material used to construct it. The varistor consists of a semiconductor junction formed by two layers of different metal oxide materials. When the voltage applied to the varistor exceeds its rating, the junction’s resistance increases exponentially and its current decreases. This decrease in current prevents any further increase in the voltage and protects the circuit or system from damage. Upon the removal of the overvoltage, the varistor returns to its original low resistance state.

The V625LT40APX2855 is a reliable, robust, and economical device suitable for a wide range of applications and can help protect and extend the life of sensitive electronic components and circuits.
