TVS – Varistors, MOVs are types of voltage-dependent protection components used in circuitry to protect the system from excessive transient currents. The Varistors, MOVs devices are like a resistor, except that the resistance decreases with increasing voltage. One such high-quality protection component is the VC1210K251R035. It is a planar varistor effectively clipped to an infinite resistance above a specified voltage. With a maximum peak current rating of 75A and a leakage current of 5A, this component offers exceptional protection against transient overvoltage.

Application Field

Due to its high peak current rating and low leakage current, the VC1210K251R035 is suitable for use in many applications, including:

• Peripheral devices, such as power supplies and circuit boards
• On-board circuits and sensors
• Protection of sensitive electronic components
• Protection of embedded systems

This component has various advantages over other types of protection components, including a higher energy dissipation, lower clamping voltage, and higher surge-current capabilities. It is also more resistant to thermal and electrical aging than other protection components.

Working Principle

The VC1210K251R035 works by redirecting excess transient current away from sensitive electronic components and systems. When a voltage above a certain threshold is applied across it, it becomes a low impedance path, allowing the transient current to pass through the component instead of the system. This in turn protects the system from damage due to overvoltage. Due to its high peak current rating and low leakage current, it is suitable for use in a wide range of applications.

The VC1210K251R035 also has a self-healing feature which helps it to recover from sustained electrical stress. That is, when a transient current passes through the component, the component’s resistance returns to its original value once the current has ceased. This helps to prevent the system from experiencing any long-term damage caused by overvoltage.

Conclusion

In conclusion, VC1210K251R035 is an effective protection component that can protect circuits from excessive transient currents. It has a high peak current rating and low leakage current, making it suitable for a wide range of applications. It also has a self-healing feature which helps to protect the system from long-term damage due to overvoltage. For these reasons, it is an ideal choice for circuit protection applications.
