Introduction

ERZ-V14D121 belongs to the TVS – Varistors, MOVs family. This article will introduce the application field and working principles of ERZ-V14D121.

Application Field

ERZ-V14D121 is a high voltage diodes able to protect against static charges. It can be used in commercial and industrial electronic systems. Such as railway communication systems, solar power systems, Automatic Meter Reading(AMR) systems, and other power systems of heavy vehicles.

Working Principle

ERZ-V14D121 is a breakdown device which ables to shunting excess current away from a circuit quickly to protect the system and provide voltage clamping protection. It has a metal-oxide layer on the device\'s chip, and when it working, the metal oxide layer will break down and conduct the current, and relieve the voltage or current spike to protect the device.

Conclusion

ERZ-V14D121 is an effective and reliable device which able to provide voltage clamping protection and shunt the excess current away from a circuit quickly. It has broad application fields in railway communication systems, solar power systems, Automatic Meter Reading systems and other power systems of heavy vehicles. The working principle of ERZ-V14D121 depends on the metal-oxide layer on the device\'s chip, when it working, the metal-oxide layer break down and conduct the current, and relieve the voltage or current spike to protect the device.
