V120ZC20PX2855 application field and working principle

V120ZC20PX2855 belongs to the category of TVS -Varistors, MOVs (transient voltage suppressors). It is a semi-conductor component that is designed to protect sensitive electronic equipment from voltage transients or spikes that may occur due to lightning, AC power loss and other surge events. It has a wide range of applications such as telecom systems, protection circuits for medical equipment, computers, industrial control systems, transistor /IC protection, and consumer electronics including AC adapters, DC motors, automobiles, batteries, and more.

The V120ZC20PX2855 works through the principle of diverting and dissipating excess electrical energy away from the vital circuit components, when a transient voltage attack occurs. During this process, the voltage spike is clamped and the electrical energy is absorbed and converted into heat. This prevents the voltage from reaching dangerous levels that may burn out or disrupt the circuit.

Typically, a MOV (Metal Oxide Varistor) or a TVS diode will be part of the circuit and connected to the same ground. The MOV and TVS function together to form a complete transient suppression circuit. The MOV operates at a near-constant clamping voltage, while the TVS acts like a back-up and kicks in when the MOV can no longer protect the circuit against higher voltages.

The V120ZC20PX2855 has an instantaneous response time of less than 1 nano-second, which is impressively fast and ensures optimal protection for sensitive electronic equipment. It is also capable of dissipating a maximum of 850 watts of power, making it suitable for circuits that require intensive energy absorption.

In terms of design, the V120ZC20PX2855 comprises of two diodes with reverse-biased connections, a varistor element enclosed in a case, two contact /terminal points on the side, and an integrated thermal fuse. All of these features ensure maximum safety during surges, which makes this component suitable for a wide range of applications.

The V120ZC20PX2855 also offers improved stability and low capacitance, as well as reliability and a wide operating temperature range of -35 Celsius to +105 Celsius. Furthermore, it has a low leakage current, low capacitance, low leakage current – making it a good choice for sensitive electronic equipment.

Overall, the V120ZC20PX2855 is a great choice for any application that requires surge protection. It is capable of dissipating a large amount of power in a fraction of a second, ensuring fast response and optimal protection against transient voltage surges.
