TVS – Varistors, MOVs are the two major components of the surge protection device used in the industry. V120ZU20PX2855 is an advanced surge protection device that can be used in various industry applications and devices due to its advanced features. In this blog, we discuss in detail the application field and working principle of V120ZU20PX2855.

Application field

V120ZU20PX2855 is an advanced surge protection device ideal for use in industrial devices and appliances. It is a bidirectional device that is capable of providing surge protection against both normal and overvoltage surges. This device is an ideal choice for protecting delicate electronic components such as power supply, communications equipment, video equipment, computer CPU, medical equipment and more.

V120ZU20PX2855 is one of the most popular surge protection devices used in the industry as it provides superior protection against various types of overvoltage or undervoltage surges. The device has a very wide range of operating voltage range, which can easily withstand up to 500V for an extended period of time. This makes it an ideal choice for applications that require high voltage surge protection.

V120ZU20PX2855 also offers excellent transient overvoltage protection against high peak voltages, which can range up to 12kV/4kV (L-N). This makes it a great choice for protecting power supply and other delicate electronic components from overvoltage spikes. The device can also provide protection against common mode, line-to-line and differential mode surge protection.

Working Principle

V120ZU20PX2855 is a bidirectional surge protection device that works by shunting the electrical current away from the sensitive electronic components from the point of surge. It is normally connected directly across the load in a two-wire configuration. The device is also equipped with a thermal fuse that prevents thermal runaway of the device due to prolonged overvoltage. This is a great feature that ensures the device will not be damaged by prolonged overvoltage and will automatically reset itself after the surge passes.

The device works by using an electrically conductive metal pad and a semiconductor material known as metal-oxide varistor (MOV). This MOV is connected to the metal pad and is held at a certain voltage by its series resistance. When an overvoltage surge is applied to the device, the MOV changes its electrical resistance and the current is diverted away from the sensitive components. The diode then acts as a protection circuit and absorbs the overvoltage surge, protecting the sensitive components from the damage.

V120ZU20PX2855 proves to be an efficient surge protection device. It is an ideal choice for industrial applications as it provides superior overvoltage protection and reliability. It is also an economical device that offers reliable protection for various applications.
