Varistors, commonly known as Transient Voltage Suppressors (TVS) are devices primarily used for protecting electrical circuitry from a variety of environmental influences. They provide over-voltage and limited over-current protection by briefly absorbing that energy during transient voltages caused by a variety of sources, such as lightning or electro-magnetic interference (EMI).

The V150ZS1PX2855 is a varistor (TVS - Varistors, MOVs) designed to protect a circuit from over-voltage conditions while remaining very compact in size. It is capable of handling an impressive surge peak power of 3.3kW and withstands a continuous voltage of 600V. Additionally, its capacitance of 1,050pF ensures it is able to adequately protect various electronic components. Its maximum rated voltage is 275V, and its rated DC current is 5mA.

The TVS V150ZS1PX2855 displays excellent surge backlash characteristics, as it can respond to over-voltage situations within approximately 25ns. This fast response time makes it suitable for a wide range of applications. Furthermore, the device is resistant to reverse currents and temperature cycling, affording it superb long-term reliability.

The working principle of a varistor is relatively straightforward. The varistor is made up of a semiconductor layered with a metal oxide material. When a voltage exceeding the device’s rated breakover voltage is applied, a current starts to flow through the varistor that is dependent on the voltage’s amplitude. This results in a reduction in the device’s breakover voltage and any additional currents will be drawn away from the protected circuitry. This current drastically increases the device’s power dissipation, allowing it to safely absorb any additional energy and then revert back to its maximum breakover voltage.

Due to its impressive features, the V150ZS1PX2855 is suitable for a wide range of electronic applications. Such applications can include voltage exceeding protection circuits for motor control systems, printed circuit board protection, and protection of multi-functional and portable devices. Other applications can include protection systems for consumer, automotive, as well as medical electronics.

In conclusion, the V150ZS1PX2855 is a highly efficient, reliable, and compact device for providing over-voltage protection in a variety of electronic applications. The device’s fast response time and wide list of available applications makes it well suited for a range of industrial and consumer applications. Additionally, its ability to absorb multiple surges of voltage and its robust design ensures good long-term reliability.
