TVS (Transient Voltage Suppressor) and Varistors (Metal Oxide Varistors) are electronic components designed to protect sensitive circuits and systems from electrical over-voltage and over-current damage. A TVS is basically a zener diode with a large junction size. This gives it a very fast response time when exposed to over-voltage and over-current, making it more suitable for applications that require fast response time, such as surge protection for sensitive electronics. A MOV (Metal Oxide Varistor) is a type of resistor that changes its resistance in response to changes in applied voltage. The resistance of a MOV is relatively high until it reaches a certain voltage, at which point the resistance drastically drops down. This is useful for clamping over-voltage to a safe level and is used in many electronic applications such as consumer electronics, industrial systems and automotive applications.

Varistors, or Voltage Dependent Resistors, are non-linear electronic components that are designed to provide protection from over-voltage and over-current damage. Varistors work by having a very low resistance value at normal voltages, but become increasingly higher in resistance as the applied voltage increases. When a varistor is exposed to an over-voltage, the resistance of the device increases dramatically, thus reducing the amount of current that can flow through it.

The 2859505 Varistor is a Metal Oxide Varistor (MOV) designed for applications that require protection from high levels of ESD, EFT and surge currents such as direct current (DC) power supplies. The MOV is constructed from a Zinc Oxide-based ceramic and has been rated for operation up to 150 Volts with a maximum allowable peak surge current of 30 Amps. It is rated for 26 dB of ESD protection and 35 dB of EFT protection.

The working principle of the 2859505 Varistor is based on its non-linear properties. When exposed to an over-voltage, the resistance of the device increases dramatically to limit the amount of current that can flow through it. This protective action helps protect sensitive circuits from over-voltage and over-current damage. The MOV also provides a low voltage-drop which keeps the risk of voltage over-shoot to a minimum.

The 2859505 Varistor is ideal for use in a variety of applications such as consumer electronics, industrial systems, automotive, etc. It can be used in range of power supplies and transient protection circuits to provide reliable and effective over-voltage and over-current protection.

In conclusion, the 2859505 Varistor is a type of MOV (Metal Oxide Varistor) that is designed to provide protection from high levels of ESD, EFT and surge currents. It works by increasing its resistance dramatically when exposed to an over-voltage. The MOV also provides a low voltage-drop that helps prevent circuit damage due to over-voltage and over-current. It is suitable for a range of applications such as consumer electronics, industrial systems and automotive.
