TVS (Transient Voltage Suppressors) are used to protect sensitive electronic equipment from the damage caused by electrical surge events. Varistors, MOVs (Metal Oxide Varistors) and ERZ-E11E621 are just one example of the kind of protection devices used. This article will give an overview of the application field and working principle of the ERZ-E11E621.
Application Field
The ERZ-E11E621 is a lightweight, high voltage varistor used in lightning and surge protection circuits. It offers high surge absorption capabilities (250V max. continuous operating voltage) and a large range of working temperatures (-55°C to +125°C). The device can be used in a wide range of application fields, including automotive, power sources, lightning and surge protection, instrumentation, home appliances, and electrical & electronic equipment.
Working Principle
The ERZ-E11E621 is made of zinc oxide (ZnO), and is shaped in a disk or cylindrical form. When the device is installed in a circuit, a typical V-I curve is observed. The ZnO material in the device functions as a large insulator until a certain voltage is applied. When this voltage is exceeded, the material switches to a conducting state, absorbing the surge energy and protecting the components downstream. This is known as the “clamping voltage” and is indicated on the device’s datasheet. In addition, the device has a self-healing ability, so it is able to repair itself in case of damage.
Conclusion
The ERZ-E11E621 is a reliable and robust varistor device used in a wide range of lightning and surge protection circuits. It has a large range of working temperatures and offers high surge absorption capabilities. The device is able to self-repair in case of damage and is a cost-effective solution for protecting sensitive electronic equipment from electrical surge events.
