TVS (transient voltage suppressors), or varistors, are components used to protect against transient voltages, surges and spikes in electronic circuits. They work by limiting the amount of voltage that can pass through the circuit, and are often used in power supplies and electrical power lines. MOVs (metal oxide varistors) are also used, and can be used in combination with TVSs. The V120ZA20P is a type of varistor that is often used in TVS applications.

The V120ZA20P is designed to provide transient over-voltage protection. It is designed with an induction shield that helps protect against line transients, and is well-suited for applications in high-frequency environments. The device is also equipped with an internal Faraday cage, which helps reduce the risk of ESD (electrostatic discharge) damage, and prevents unwanted currents from entering the circuit. The device also has a wide operating temperature range, from -40°C to 95°C.

The working principle of the V120ZA20P is based on two basic principles. The first is that the varistor’s resistance is temperature-dependent. When the temperature is higher, the resistance is lower. The second is that the varistor’s resistance is proportional to its voltage rating. As the voltage across the varistor increases, the resistance increases. By combining these two principles, the device is able to provide surge protection. When a surge or spike is detected, the varistor’s resistance increases, and the excess voltage is diverted away from the circuit.

The V120ZA20P is often used in a variety of different applications, such as over-voltage protection in power supplies, automotive electronics, LED lighting, audio-video systems, telecom, medical equipment, and more. In addition, the device is often used in surge protection in server and storage systems, networking equipment, or a variety of other industrial control systems. It can also be used in torque limiters, brake systems, and other applications where transient protection is needed.

The V120ZA20P is a reliable and cost-effective solution for protecting against transient voltages, surges, and spikes. Its robust design and wide operating temperature range make it suitable for a variety of applications, and its induction shielding and Faraday cage help protect against ESD damage and reduce interference. In addition, its temperature-dependent and voltage-dependent resistances provide reliable surge protection to keep the circuit safe from harmful transients.
