TVS (transient voltage suppressors) and MOVs (metal-oxide varistors) are often used together to protect electronic circuits against overvoltage. The ERZ-E05E391 application field and working principles are not clearly understood by many. This article will help shed some light on the subject.

ERZ-E05E391 is a metal-oxide varistor which provides a solution to problems associated with voltage transients which are usually caused by overvoltage, lightning or electrostatic discharge. The ERZ-E05E391 provides protection against such transients by reducing the voltage to a safe value and absorbing the energy in the electrical circuit via a low impedance. The working principle of the ERZ-E05E391 is as follows: when a voltage above the model’s Rated Voltage is applied, electrons from the zinc-oxide material, also known as a dielectric material, move to the anode. This process is known as “tunnel electron conduction.” This in turn sets up a voltage-drop and thereby reduces the voltage across the device.

ERZ-E05E391 is suitable for voltage transients and electrostatic discharge in consumer electronics such as TVs, DVD players, set-top boxes, computers, and personal digital assistants. It also provides protection for automotive and industrial electronic circuits when subjected to extreme environmental conditions. The device has a high-level ESD immunity and can be successfully applied in high-frequency data lines up to 1GHz. The device comes in a lead-less surface mounted (SMT) design and is available in RoHS-compliant packaging.

The ERZ-E05E391 is a high-performance protector that enables designers to cost-effectively protect their circuits from voltage transients and Electrostatic discharge. It is easy to install and requires minimal board space, making it an ideal choice for designs with tight space constraints. It also offers high reliability and performance, providing peace of mind that the devices are fully protected.

In conclusion, the ERZ-E05E391 provides a reliable and effective solution to voltage transients and ESD protection in a wide range of applications. It is a high-performance protector that offers cost-effectiveness, reliability, and performance. Its lead-less SMT design makes it easy to install and requires minimal board space, allowing designers to create designs with tight space constraints while still guaranteeing protection of the electronic circuits.
