ERZ-C32CK201W Application Field and Working Principle

The ERZ-C32CK201W is an over-voltage protection device that belongs to the larger family of transient voltage suppressors (TVS). It is a type of voltage-dependent resistor (VDR) commonly referred to as a Metal Oxide Varistor (MOV). It is a solid-state component with no electrical connections between the two metal plates, and thus it can provide robust protection against surges in voltage caused by lightning and power surges.

MOVs are used to protect against surges that are produced by reverse-engineered power supplies, such as those found in LED arrays and those produced by the back-feeding of solar power sources. By using an MOV, the surge in voltage that is caused by this back-feeding process can be quickly dissipated, resulting in a voltage spike that is manageable and isolates the circuit that is being protected from the rest of the circuit.

The ERZ-C32CK201W consists of a set of two metal plates, with a ceramic insulation layer between them. The metal plates contain a ceramic element, with zinc oxide (ZnO) crystals being held between them. When the voltage across the plates exceeds a certain threshold, the ZnO crystals become electrically active and conduct current, which dissipates the energy of the surge across the metal plates, lowering the voltage that reaches the protected circuit.

The ERZ-C32CK201W has a breakdown voltage of 32V and a rated current of 200A. This limits the energy that can reach the protected circuit to a safe level. The device is designed to dissipate the energy of surges of up to 32V and values above that will cause a significant increase in the temperature of the ZnO element, which may cause it to break down and fail.

The ERZ-C32CK201W is designed to provide surge protection for sensitive applications, such as LED arrays, solar power sources and electric vehicles. It is also suitable for use in the medical and industrial fields and can be used to protect a wide range of electronic equipment, including sensitive electronic components.

The ERZ-C32CK201W is a simple and effective solution for providing surge protection for sensitive electronic components and equipment. Its robust design and high current rating make it suitable for a wide range of applications, from consumer devices to industrial control systems. In addition, its low cost and small size make it an ideal choice for many applications.
