TVS (Transient Voltage Suppressors) - Varistors, MOVs, and V385LA7PX2855 are important components in power electronics. This article is about the applications and working principle of V385LA7PX2855, which is a MOV (Metal Oxide Varistor) used for transient voltage suppression.

MOVs are widely used in electrical equipment and have become an indispensable part of electronic components. It is mainly used for overvoltage protection, AC and DC power line protection, and low frequency interference protection. V385LA7PX2855 MOV has good EMI filter performance, high surge current capacity and small size, which makes it suitable for a variety of applications.

V385LA7PX2855 has a wide range of applications. Its typical application fields are mobile phones, consumer electronics, multimedia products, computers and peripherals, office automation products, game consoles, tracking systems, medical equipment, aviation and military equipment, power supplies, external power adapters, and car electronics.

The working principle of V385LA7PX2855 is quite simple: it acts as a variable resistor to reduce the voltage when the voltage value is too high. It works by using a positive temperature coefficient material (PTC), which connects the two terminals. When the voltage exceeds the specified limit, the PTC material\'s electrical resistance will increase rapidly, thereby cutting off the electrical current and limiting the voltage to the safe level.

Moreover, V385LA7PX2855 MOV also has excellent temperature coefficient. The temperature coefficient is determined by the difference between the set voltage and the rated voltage when the temperature changes. Its temperature coefficient is generally in the range of ±10V/°C.

In summary, V385LA7PX2855 belongs to the MOV (Metal Oxide Varistor) used for transient voltage suppression. It is widely used in electrical equipment, with good EMI filter performance, high surge current capacity and small size. Its working principle is that it acts as a variable resistor to reduce the voltage when the voltage is too high. It also has excellent temperature coefficient and is suitable for mobile phones, consumer electronics, multimedia products, computers and peripherals, office automation products, game consoles, tracking systems, medical equipment, aviation and military equipment, power supplies, external power adapters, and car electronics.
