TVS - Varistors, MOVs, are typically used in a variety of circuits and systems to protect against the damaging effects of overvoltage transients. The ERZ-E11A241CS Varistor is one type of TVS that can be used in a wide range of applications and systems. This article will explain the application field and working principle of the ERZ-E11A241CS Varistor.

Application Field of ERZ-E11A241CS Varistor

The ERZ-E11A241CS Varistor is an Unidirectional Varistor, which means that it only conducts in one direction and can provide bidirectional over-voltage protection. It is typically used in power supply systems and power transmission or distribution systems. This Varistor is particularly well-suited for providing high-level surge suppression in systems with high mains overvoltage and high transients. These Varistors can also be used to protect equipment from malfunction due to high peak currents caused by lightning or other sources of electrical disturbance.

Working Principle of ERZ-E11A241CS Varistor

The ERZ-E11A241CS Varistor is based on zinc oxide technology. When an excessive amount of voltage is applied across its junction, it will start to conduct, allowing the excess voltage to be discharged. This is done by creating a large voltage drop directly across the Varistor. When the voltage across its junction falls back to normal levels, the Varistor will stop conducting, isolating the protected circuitry from the excess voltage.

The ERZ-E11A241CS Varistor has a rated voltage of 220V AC and a maximum discharge current of 10kA. It also has a high voltage capability of up to 2.5kV, which is great for providing protection against overvoltage transients. The Varistor’s temperature range is -40°C to 85°C, making it suitable for various types of environments and applications.

The ERZ-E11A241CS Varistor provides lots of protection at a very compact form factor. Additionally, it is a low-cost solution for protecting various types of circuits and systems from unexpected voltage transients.

Conclusion

The ERZ-E11A241CS Varistor is a great solution for providing protection against overvoltage transients and can be used in a wide variety of circuits and systems. It is based on zinc oxide technology and provides a maximum discharge current of 10kA and a high voltage capability of up to 2.5kV. Additionally, it is a low-cost solution for providing protection against voltage transients.
