TVS – Varistors, MOVs, are surge protection components used to prevent voltage overshoots and spikes in applications that require protection from over voltage. V47ZU1PX2855 Varistor is one such component from Vishay which can be used for protecting against lightning and surge induced overvoltage. This article will discuss the application fields and working principle of V47ZU1PX2855 Varistor.

Varistors are commonly used for protection against lightning and surge induced overvoltage. They are typically used in high voltage systems and can be found in many applications such as modems, computers, monitors, and other consumer electronic devices. As a protection component, the V47ZU1PX2855 Varistor can be used to protect against overvoltage and high voltage spikes of up to 850 V AC / DC.

The V47ZU1PX2855 Varistor features ceramic outer casing, coated with zinc oxide material. The zinc oxide material helps to absorb energy, discharging, it, thus reducing the overvoltage. The varistor voltage of the V47ZU1PX2855 Varistor is 470 V ac RMS / 840 V DC. The maximum surge current peak that can be absorbed by this Varistor is 0.8 kA (8 20 μs). The power rating of the V47ZU1PX2855 Varistor is 65J, and it is RoHs Compliant.

In operation, the V47ZU1PX2855 Varistor will respond to voltage surges and spikes. In the presence of an overvoltage event, the V47ZU1PX2855 Varistor will act as a load, drawing current from the circuit and discharging it through the zinc oxide. This helps to prevent the circuit from being damaged by the overvoltage.

V47ZU1PX2855 Varistor can be used in various applications. It can be used to protect computers and modems from voltage spikes and surges, as well as to protect power supplies and LED power supplies. It can also be used to protect goods such as solar panels and electric vehicles from overvoltage. In terms of automotive applications, V47ZU1PX2855 is used in automotive systems such as brake systems, airbag systems, and fuel systems, where it provides overvoltage protection to the sensitive electronic systems present in vehicles.

In conclusion, V47ZU1PX2855 Varistor is a surge protection component from Vishay. It features ceramic outer casing, coated with zinc oxide material that absorbs energy and reduces the overvoltage. It is suitable for high voltage systems and can be used for applications such as protecting computers and modems, as well as automotive systems. It provides optimal protection to sensitive electronic components in the presence of an overvoltage event.
