ERZ-E11A621 Circuit Protection

ERZ-E11A621 Application Field and Working Principle

ERZ-E11A621 is an overvoltage protection device belonging to TVS (Transient Voltage Suppressors) - Varistors, MOVs (Metal Oxide Varistors). It is used to protect a system from overvoltage and overcurrent, and also to suppress transient voltages in AC/DC circuits.

ERZ-E11A621 consists of two electrodes - an anode and a cathode which are separated by a semiconductor layer. When a reverse voltage is applied between the electrodes, the electric field created by the reverse voltage causes “holes” to be generated in the semiconductor layer, which is known as “reverse biased”. Once the reverse voltage has reached a certain level, the holes in the semiconductor layer will travel to the anode and create a conductive path between the two electrodes.

When the voltage surpasses a certain level (the breakdown voltage of the component), the electric field generated by the rising voltage will cause a massive discharge current to flow in the external circuit. This will reduce the applied voltage and help to protect the equipment from overvoltage and overcurrent.

The working principle of ERZ-E11A621 is simple and straightforward: it works to protect the equipment by providing a quick and efficient short-circuit path for the overvoltage and overcurrent. Once the voltage is reduced to the normal level, the short-circuit path will be broken and the component will begin to operate normally.

The ERZ-E11A621 is a high-performance device designed for use in a wide range of applications. It is suitable for various applications, such as consumer electronics, computers, telecommunications equipment, automotive electronics, and more. It provides superior protection against ESD (electrostatic discharge) and lightning. It is designed for high temperature operation and has a very high surge handling capability.

ERZ-E11A621 is a cost-effective, reliable, and reliable choice for overvoltage and overcurrent protection. It is designed to provide protection against transient overvoltages and overcurrents, and can help to protect the system from damage caused by transient overvoltages or overcurrents. It is a small and lightweight device, making it ideal for applications where space is limited.

The ERZ-E11A621 is designed to be used in a variety of environments and settings, including industrial, commercial, and residential applications. It is easy to install and provides excellent performance and protection.
