TVS (Transient Voltage Suppressors), MOVs (Metal Oxide Varistors) and V22ZS05PX2855 are three types of electrical components usually classified under the same product group. They are designed to provide protection for electronic circuit from high voltage transients or lightning surges which can damage or destroy the device. V22ZS05PX2855 Varistor which is also known as “surge protective device” is an available type from Littelfuse Inc. and is more suitable for lightening protection.

V22ZS05PX2855 Varistor is a specific type of semiconductor device constructed of zinc oxide pellets that are compressed into a ceramic case. The main function of this component is to reduce the stress on an electrical system by passing and dissipating a surge current from an unexpected voltage spike or over-voltage in the system. The amount of current that it can handle depends on the size of the varistor as well as the complexity of the circuit it is protecting.

The trigger voltage or VDC of this particular type is 28V and it has a TVS (transient voltage suppression) current rating of 5A or 5,000A for frequency 10kHz. It is capable of handling maximum peak pulse voltage of 42V.The residual voltage of the V22ZS05PX2855 Varistor is 1.5V. This device is usually available in a SMD (Surface Mounted Device) package, with physical size of 0.6mm × 0.6mm.

Due to its compact size and high pulse current handling capabilities, the V22ZS05PX2855 Varistor is suitable for both MOSFET and control circuits that are typically used in automotive applications such as lighting, climate control, entertainment systems and powertrain control. The device can also be used to protect parts and components which require adequate protection from sudden voltage withdrawal and surges. Moreover, this Varistor can also be used in audio and radio frequency circuits where low noise from surge currents is required.

The working principle of V22ZS05PX2855 Varistor is based on the voltage-dependent behavior of certain materials, where a sudden change in voltage causes electrons to redistribute themselves through the material. In its simplest form, a varistor is a two-terminal nonlinear resistor. As the voltage rises across the two terminals, a current continues to rise until the current reaches its limit and then goes back to its baseline. Thus, when the voltage exceeds the stated trigger voltage, electrons start to move from high-resistance regions across the material, eventually balancing the voltage and increasing the current. The resistance of the material also falls, allowing the voltage to be clamped to a safe level until the current has passed.

V22ZS05PX2855 Varistor is a common choice for portable and industrial applications as it is highly reliable, cost-effective, easy-to-use and capable of handling a wide range of transient voltage spikes. The device is also available in a wide variety of applications such as signal line protection, automotive, RF and frequency applications where transient voltage spike protection is required.
