TVS - Varistors, MOVs
The ERZ-E08A221CS is a modern TVS - Varistor, MOV, primarily designed for surge protection. It works by using a voltage dependent reverse breakdown to funnel excess power into a safe sink, preventing damage.
Application
The ERZ-E08A221CS is designed with a surge transient current rating of 8A and a clamping voltage of 221V. It is typically used to protect general electronic circuits from thunder and lightning surge transients and similar harmful surges. It is durable and can support up to 5,000 operations at its rated voltage and is UL approved for industrial and consumer applications.
Working Principle
The ERZ-E08A221CS is a non-linear, metal oxide, high reliable surge absorber and is designed to operate a specific breakdown voltage. Its working principle is based on absorptive and conductive mode details. When surge current is absorbed, the majority of the energy is dissipated through the exposed junction area, while the remaining energy dissipates through the ceramic substrate. The exposed junction area works as the energy sink, due to its distributed resistance, which absorbs and dissipates the energy.
The metal oxide element\'s dynamic resistance plays a crucial role in absorbing the energy, and the varistor\'s dynamic resistance is minimized at the breakdown voltage. Once the overload current has passed and the voltage goes below the breakdown voltage, the dynamic resistance increases and further energy absorption occurs. This ensures the surge current is absorbed and dissipated in a safe and controlled manner.
Conclusion
The ERZ-E08A221CS provides an ideal solution for surge protection in general electronic circuits. It is a reliable component with an 8A peak surge current rating and 221V clamping voltage, and is suitable for consumer and industrial applications. The ERZ-E08A221CS is based on absorptive and conductive principles for fast response time and efficient energy absorption.
