TVS - Varistors, MOVs is an electronic component used for protection circuits. It absorbs transient overvoltages and limits the voltage to a safe level within specified time. ERZ-E08E221 is a product within this field and its application field and working principle will be described as follow:

Application Field

The ERZ-E08E221 product belongs to the special transient voltage surge suppressor (TVS) series with high wave pulses in parallel connection. It offers a low on-state voltage and very robust impedance against high surge pulses without any additional external elements. Typical application fields of this product includes lightning protection for IEC port protection, automotive electronics, compressor and air conditioning systems.

Working Principle

The working principle of the ERZ-E08E221 product is based on the nonlinear characteristics of semiconductor to reduce the voltage. Its on-state voltage is typically 0.99 V; its on-state resistance is typically 3.3 ohms, and its power dissipation is typically 0.1 W. Its working principle is same as normal TVS, varistors and MOVs. When a voltage higher than its on-state voltage occurs, it can absorb the excess voltage and protect the device from overvoltage.

It uses high-energy semiconductor material and its breakdown voltage can reach million volts per microsecond. The semi-conductor structure of the TVS can absorb large above-normal voltages, preventing further system damage. It has very low stand-by current and low dynamic resistance which make it suitable for high-speed signal and DC protection. By using this product, it can protect DC circuit from over voltages induced by lightning or other fault condition.

ERZ-E08E221 also features a high clamping voltage for many different kinds of circuits. The clamping voltage will automatically adjust according the breaking voltage of the product and the current member, suppressing the overvoltage. With its high performance and reliable stability, it is the ideal choice for many static and dynamic DC protection applications.

The ERZ-E08E221 is an ideal high-current protection component for IEC port protection, automotive electronics, compressor and air conditioning systems. It provides reliable protection against overvoltage and overcurrent. Through its advanced nonlinear characteristics, the device can be used to reduce the risks of surge damage and ensure device safety and system stability.
