ERZ-E11A751CS

TVS - Varistors, MOVs are designed to provide reliable protection from overvoltage transients caused by lightning or other electrical events, increasing the overall life of the protected circuit. ERZ-E11A751CS is one of them. It is suitable for the protection of Ethernet, the high voltage port of industrial communication module, and the isolation protection of motor drive interface.

ERZ-E11A751CS Application Field

The ERZ-E11A751CS can absorb but not conduct large surge current and clamp surge voltage in the circuit. This device effectively limits transient voltage and greatly increase immunity to protect electromechanical equipment from lightning and other overvoltage disturbances, providing a wide range of protection for communication lines, adjustable frequency drives, etc. ERZ-E11A751CS can also be used in AC and DC installations that require discharge current protection.

ERZ-E11A751CS Working Principle

ERZ-E11A751CS is composed of a ceramic body and two metal electrodes. When the input voltage exceeds the clamping voltage, the Zener diode starts to work, and the capacitance/resistor sections work together to lower the rapid rising peak voltage, insulation and discharge overvoltage. This device blocks the discharge current and prevents overvoltage from entering the protected device thus providing effective protection.

Conclusion

ERZ-E11A751CS is a reliable device for surpressing surge current and clamping surge voltage in the circuit. It is suitable for the protection of Ethernet, the high voltage port of industrial communication module, and the isolation protection of motor drive interface. It is widely used in AC and DC installations that require discharge current protection. ERZ-E11A751CS proves to be an ideal choice for improving system stability and reliability.
