TVS - varistors, MOVs are leading components in the electrical industry and power electronics sector. The V68CH8X3313 is one such device that is widely used in a number of applications requiring surge protection and power quality control. In this article, we will explore the key features of the V68CH8X3313, its application fields, and its working principles.

V68CH8X3313-Features

The V68CH8X3313 is an ultra-compact component, measuring just 6.9mm x 8.5mm when packaged in its case. It is a self-protecting device and will trip in the event of a surge which exceeds its peak current rating. It also has built-in limited energy absorption capability, making it suitable for high frequency transient energy absorption, such as in medical equipment.

The device has a nominal capacitor rating of 330pF and a maximum current rating of 33A. It has a peak impulse current capacity of 100A, and a operating voltage of 330Vrms max. In addition, it has an impressive temperature coefficient of -19%/°C, enabling it to perform well in temperatures ranging from -25°C to 85°C.

V68CH8X3313 - Application Fields

The V68CH8X3313 is an ideal choice for environments with high levels of surge protection, as it is highly resistant to breakdown and offers excellent pulse suppression capability. It is mainly used in:

• Lighting installations
• Industrial automation
• Power supply lines (e.g. global power grid)
• Mechanical and motion control circuits
• Communications
• Military/aerospace
• Medical equipment

The device is also suitable for use in electronic equipment, including aviation electronics, telecom systems, and lead acid batteries.

V68CH8X3313 - Working Principle

The V68CH8X3313 is a varistor, and it works by clamping incoming voltage and current to a safe level. When the voltage exceeds the device\'s voltage rating, it starts to block the current flow, diverting it into its clamping area. This produces a clamping voltage, which limits the maximum voltage and current passing through the device. In this way, the device protects connected components from over-voltage and over-current surges.

The device also has self-regulating functionality. This means that it is able to sense transient (high-frequency) energy and react accordingly, providing additional surge protection. As such, the device is suitable for use in a wide range of power or communication systems as it can reduce the risk of electronic components suffering damage due to surges or spikes in voltage.

Conclusion

The V68CH8X3313 is a versatile and reliable surge protection device. It offers an impressive maximum current capacity, excellent temperature coefficient, and built-in self-regulating functionality. This makes it an ideal choice for use in a variety of applications, such as in lighting installations, industrial automation, power supply lines, communications systems, and medical equipment.
