ERZ-VF2M331

ERZ-VF2M331 is a device in TVS - Varistors, MOVs category, which is mainly used in the overvoltage protection. It functions by fact that when facing to a transient voltage, it will absorb energy and reduce the size of voltage in an acceptable range.

The rated voltage of ERZ-VF2M331 is 250Vac/1.0s, and its maximum energy is 30J. It also has an impressive surge current rating and peak pulse current up to 750A, which adds up to make ERZ-VF2M331 suitable for various protection applications.

Working Principle

When facing a voltage, ERZ-VF2M331 will conduct current between two electrodes. As the current flows over two electrodes, a voltage drop occurs between them. This voltage drop absorbs the energy of the incoming voltage pulse and thus protects the device from becoming exposed to higher voltage. The voltage drop for ERZ-VF2M331 is usually between 1.5 and 2 V. This provides sufficient protection for most applications.

Application Field

ERZ-VF2M331 can be used in various applications, including communication equipment, TV sets, uninterruptible power supplies, industrial control equipments, etc. It is also suitable for protection of the power control circuits and other sensitive electronic devices. Its ultra low capacitance and low leakage current make it ideal for high frequency circuit protection.

ERZ-VF2M331 is manufactured with non-linear multilayer element. It can be used in AC/DC, DC/DC and DC/AC power systems. It is also environmentally friendly and free from hazardous substances and halogens.

In conclusion, ERZ-VF2M331 can be used to protect most applications from transient voltage. It has a rated voltage of 250Vac/1.0s and can provide maximum energy up to 30J. It also has significant surge current and peak pulse current rating up to 750A. It is suitable for many application fields, including communication equipment, TV sets, uninterruptible power supplies, industrial control equipments and many others.
