TVS – Varistors, MOVs, or Transient Voltage Suppressors, are commonly used components for protection of sensitive devices that could be damaged by electrical over-voltage. The ERZ-E07E561 is one such component – a Dural-mode varistor. Generally, a varistor is a device that can modify or adjust the current that passes through it. It uses a semiconductor material, usually a metal-oxide, for this purpose. The ERZ-E07E561 is designed to be used on DC applications that require a wide range of DC operating voltages, and offers the additional abilities to absorb large transient currents.

The name “Dural-mode” is derived from its physical construction: a combination of two or more layers of different materials that form an arc across the layer border, giving the device its characteristic “Dural-mode” resistive property. By controlling the direction and spread of the electric field generated in this manner, it is possible to adjust the resistance of the device over an incredibly wide voltage range. This makes the ERZ-E07E561 highly resistant to impulse voltage and surge currents.

The ERZ-E07E561’s wide operating voltage range, from 5V to 600V DC, makes it an ideal choice for automotive and industrial applications. This type of varistor can be used to regulate the voltage in any application that requires a voltage range above 725V. It is also suitable for protecting electrical components from over-voltage and over-current, and can be used in applications such as surge protection in photovoltaic systems or digital video applications.

The important factor with any varistor is that it will be able to adjust the current that passes through it. The ERZ-E07E561 exhibits excellent breakdown characteristics, allowing for the precise adjustment of the current in the presence of the transient voltage. The lowest breakdown voltage is specified at 5.7 volts and the dielectric strength is said to be approximately twice that of standard metal-oxide-sulfur varistors. This all adds up to superb over-voltage protection capability.

The ERZ-E07E561 is a surface-mount design, making it suitable for a variety of applications that require cost-effective protection of sensitive electronic components. It is a lead-free, RoHS compliant device, making it environmentally friendly and helping to provide the highest level of safety and reliability.

In summary, the significant features of the ERZ-E07E561 include excellent protection against transients and surges, a wide operating voltage range from 5V to 600V DC, high dielectric strength, and RoHS compliant lead-free construction. Hence, it is an ideal component for use in automotive, industrial and photovoltaic applications, providing the highest level of safety and reliability.
