Varistors, MOVs, and TVSs (transient voltage suppressors) are components designed mainly to provide electrical over-voltage protection. VE1206K201R020 belongs to the family of TVSs. TVSs provide extremely reliable over-voltage protection for sensitive or highly integrated circuits from transient voltage such as electrical noise. In this article, we will discuss the application field and working principle of VE1206K201R020.

VE1206K201R020 is a chip form TVSs designed specifically for high-power and low-noise applications. It has protective features with low capacitance and high protection levels, making it suitable for meeting the requirements of advanced micro-controller and automotive functions. Essentially, the device is designed for protecting onboard circuits from lightning, electrostatic discharge (ESD), and other transient voltage events. Installing VE1206K201R020 in the circuit allows switching power on from over-voltage protected normal ON state to OFF state. It offers much higher levels of protection compared to the traditional MOVs or varistors.

The primary application field of VE1206K201R020 are power supplies, motor control circuits, portable electronic equipment, cell phones, and industrial automation and control systems. The device is also used in automotive body control systems, airbag control units, and anti-lock braking systems (ABS). Apart from its usefulness in industrial, automotive, and consumer products, VE1206K201R020 is also used in many other fields, such as military and aerospace, medical, and telecom applications.

The working principle of VE1206K201R020 is based on the fact that during normal operation, the protection element is kept in an open status; whereas under over-voltage conditions the protection element is changed to a low impedance status. This low impedance status shunts the application circuits and triggers the system fault. In the VE1206K201R020, the protection element is a zinc-oxide varistor, which is an ultra high-dynamic impedance material with automatic self-balancing characteristics. When the voltage exceeds a certain level, the material begins to conduct, and reduces the voltage across the protection element. This prevents damage from the over-voltage pulse.

In summary, the application field of VE1206K201R020 is wide and the working principle is based on a self-balancing zinc-oxide varistor. It is a reliable and high-performance device for protecting onboard circuits from transient voltage events. VE1206K201R020 is suitable for military and aerospace, medical, telecom, automotive, portable electronic, industrial automation and control systems, and other high-power and low-noise applications.
