ERZ-V05D470

The ERZ-V05D470 is an advanced varistor designed to provide overvoltage and transient protection for electronic circuits. As an advanced type of TVS (Transient Voltage Suppressor), it foresees various application fields for protecting different kind of electronic devices from undergoing damages due to static and surge Electric Current. Aside from industrial and automotive applications, this device is suited for very specific and high-performance application fields.

Application fields

The ERZ-V05D470 is mainly designed for use in telecommunication and industrial equipment. Its non-linear, reverse-biased operation is able to protect any equipment by limiting high voltage by restricting it to an allowed value. Additionally, its very high resistance against surge electric currents makes it suitable for Industrial Equipment, which often needs to withstand spikes or overloads. This device is also suited for Telecommunication equipment as a fail-safe solution due to its temperature-independent operation and excellent protection against voltage overshoots.

Furthermore, the ERZ-V05D470 also suits automotive application fields, for example in the field of autonomous driving. Autonomous driving requires reliable and robust high-tech electronic systems and the ERZ-V05D470 can highly help in order to make the system more reliable and resistant to surge or overload damages.

Working Principle

The ERZ-V05D470 works in a non-linear, reverse-biased operation, which means that it can only be activated when an excessive voltage is reaching it. This happens when the current passing through it starts to increase past its maximum allowed threshold. At this moment, the varistors’ intrinsic capacitance properties start to reduce the voltage rate of the current passing through it, thus protecting the equipment or system by limiting the voltage to its accepted value.

The ARMICER product is based on a metal oxide material with an encapsulated external electrode that is the main feature of its durable construction and a leakage current of less than 0.1µA. The combination of the material and electrode make the ERZ-V05D470 very reliable and resistant to different environmental factors such as temperature, pressure and humidity.
