V68ZS20PX2855

TVS - Varistors, MOVs

The V68ZS20PX2855 is a type of varistor that is widely used for different applications. Varistors are a type of voltage-dependent resistor which features a highly non-linear non-ohmic behavior. In other words, their resistance decreases as the voltage increases beyond a given point. This makes them very useful for applications wherein they help to divert and dissipate electrical surges.

The V68ZS20PX2855 is a specific type of metal oxide varistor (MOV) which is capable of handling up to 285 volts, with a maximum peak current of 20 amperes. It also has a clamping voltage of less than 130 volts, a peak power capacity of 1640 Watts, and a response time of much less than one nanosecond. These features make it ideal for use in a variety of applications, such as motor control, industrial control systems, power converters, TVS, telecom and medical devices.

Application Field

The V68ZS20PX2855 is commonly used in applications requiring efficient protection against electrical surges, such as in power supplies, motor control systems, and automatic control systems. It is also used in a variety of industrial and consumer products, including power converters, IGBT circuits, medical devices, mobile phone charging circuits, telecom circuits, and many others. Additionally, it can also be used for protection against lightning and electrostatic discharge (ESD) protection.

Working Principle

The working principle of varistors, such as the V68ZS20PX2855, is based on the voltage-dependent nonlinear resistor characteristic. When the voltage across the varistor reaches the breakdown voltage, the resistance drops sharply. As the voltage continues to increase, the resistance decreases further, allowing current to flow freely. This helps to divert and dissipate excessive electrical surges, thereby protecting other electrical components from damage. Similarly, when the voltage drops, the resistance of the varistor increases, thus preventing any current from flowing.

Conclusion

The V68ZS20PX2855 is a type of metal oxide varistor that is designed for efficient protection against electrical surges. It is widely used in a range of applications, such as motor control, industrial control systems, power converters, TVS, telecom and medical devices. Its working principle is based on the voltage-dependent nonlinear resistor characteristic, wherein it allows current to freely flow when the voltage reaches a certain point, helping to divert and dissipate any excessive electrical surges and protect other electrical components from damage.
