• Automotive – The VC040209X200WP is suitable for various automotive applications, including protection of in-car electronics from power surges.

Working Principle

The VC040209X200WP metal oxide varistor is constructed with a composite of a Zinc Oxide and other metal oxides, and connected in series with the protection circuits. When a voltage higher than its rated clamp voltage is applied, its resistance rapidly drops, and the voltage across the outlet is clamped to the device’s rated clamping voltage. This process happens very quickly, ensuring that instantaneous protection is provided. The device is designed to be able to handle high voltages and currents up to 4kV without damage.

The device is also designed with a built in fuse, to provide additional protection against excessive current levels. In the event that an excessively high current is applied, the fuse will quickly blow, preventing damage to the device and other components. The device also has an internal temperature sensing element, which will cause it to shut off, preventing possible fire hazards in applications where the device may become too hot.

Conclusion

The VC040209X200WP is a high-performance and reliable metal oxide varistor solution, providing efficient protection from transient voltage attacks in a wide variety of applications. Its UL-certified and CQC-certified protection is suitable for sensitive systems, such as data centers and telecommunications equipments. This low-cost, effective solution is also suitable for a wide range of industrial and automotive applications, providing reliable protection from overvoltage incidents.
