The ERZ-E07A391 is an important part of the TVS – Varistors, MOVs, and is a vital component for any electronic device involving vulnerabilities to surge events and lightning. The use of the ERZ-E07A391 plays an enormous role in protecting the device from damage due to its ability to absorb a tremendous amount of energy in a short amount of time.

Lightning strikes, and the power surges and spikes that come part and parcel with them can have very destructive effects on electronic devices and circuits. For this reason, the ERZ-E07A391 is designed with extreme vigilance to withstand these high energy it inevitably will be exposed to in its life.

The ERZ-E07A391, is an example of a transient voltage suppressor, and provides high levels of transient voltage protection. The device is typically used in power line protection, and is able to instantly react to spikes/surges of up to 10 kilojoules of energy with extremely short response times – typically below 0.5 milliseconds.

The device works by using the applied voltage to particular the depletion of a predetermined voltage level. This breakdown threshold voltage is referred to as the ‘clamping voltage’, and allows the device to clip off any excess voltages/surges, dissipating the energy in the form of heat, allowing it to maintain a stable power.

The output of the ERZ-E07A391 is a leakage current. This current has a broad range of applications, including data protection, signal concerns, and power line protection. It also helps to avoid any regenerative issues and offers a wide selection range of difficulties.

This device uses a metal oxide varistor element. Metal oxide varistors were developed to protect sensitive electronic elements from high energy spikes, but function in an opposite manner to Transient Voltage Suppressors in that instead of preventing excess energy flowing through, their role is to limit the energy flowing. This method also helps to absorb energy from transients now sudden energy increases, yet it is important to remember that Metal Oxide Varistors drawback of Metal Oxide Varistors is that their energy dissipation is relatively low.

The ERZ-E07A391 builds on this technology by combining it with zener diodes to offer the best-of-both-worlds, robust and fast-acting surge protection device to instruments, devices and equipment of all sizes.

The ERZ-E07A391 offers a range of features including surge dissipation and overcurrent detection and protection, fast response times, deep-discharge protection, vibration resistance, and air gap protection.

When it comes to protection against surges and spikes, the ERZ-E07A391 is an excellent choice for protecting sensitive electronic equipment and keeping them functioning efficiently. Its low clamping voltage ensures it can protect against damaging power levels, while its fast response time keeps these infrequent events from having seriously detrimental effects.
