TVS (transient voltage suppressors) as a important element in electronic system circuits to reduce transient signals, are often used in many applications from consumer products, manufacturing systems, industrial measurements and more. ZV20K1210T401N is the specific one type of TVS element. This product belongs to Varistors and MOVs family, which provides reliable surge protection and transient voltage and current suppression.

The ZV20K1210T401N can be broadly applied in many electronic applications, such as machines, pumps, motors, and other power related equipments; appliances, air conditioners, refrigerators, microwaves as household electronics; batteries, transformers, solar cells in electric power system; vehicles’ electronic equipments, signals systems, and alarm systems; as well as telecommunication equipments.

In term of its working principle, ZV20K1210T401N is designed based on the concept of Varistor, a kind of devices which can offer protection against high transient overvoltage caused by ESD, lightning, and electrostatic noise. It has three-terminal device which is made of composite semiconductor material that is suitable for different fields. This device features low leakage, high surge current capability, outstanding capabilities of voltage protection, and good clamping ability.

To simplify it, the working principle of ZV20K1210T401N can be illustrated as following. Once an electrical signal encounters a transient overvoltage, ZV20K1210T401N will detect it. Then this device will conduct current to the ground to handle the overvoltage by breaking down its own characteristics and build a low impedance path. In this low impedance current path, voltage will keep drop until the current is flowing back to zero. Therefore, high transient overvoltage caused by ESD, lightning, and electrostatic noise will be suppressed until a safe normal voltage range is reached, which then can protect other equipments.

In summary, ZV20K1210T401N belongs to Varistors and MOVs family, is often applied in machines, pumps, motors, and other power related equipments; appliances, vehicles’ electronic equipments, signals systems, and alarm systems; as well as telecommunication equipments. And its working principle is based on Varistor device, which is able to detect transient overvoltage, build a low impedance path, conduct current to the ground and suppress high transient overvoltage until a safe normal voltage range is reached.
