The V68ZA20PX2855 is a part of the Varistor family of transients voltage surge suppressors that are used in a number of electrical systems. The components of this type of component are metal oxide varistors (MOVs) with high resistance to transients. The MOVs act as electrical short-circuits, allowing current to pass through them when the voltage rises above a predetermined threshold.

When exposed to a current surge, the MOV reduces its resistance to near zero, allowing the current to pass through to the protected circuit without damaging it. The MOVs also serve as a protective clamp, allowing the current to pass through the varistor only when the voltage exceeds its ratings. The MOV is usually placed within the circuit, typically close to the power supply, and can also be placed near sensitive components that require protection from transient voltage.

The V68ZA20PX2855 is designed specifically for use in system protection against voltage transients and is commonly used in personnel safety applications. The varistor is designed with a low capacitance, allowing it to handle high-frequency current surges. The varistor also has a high current rating and energy absorbing capability, enabling it to effectively handle fast pulsed current surges.

The V68ZA20PX2855 is typically used in applications requiring personnel safety such as consumer electronics, computer systems, and medical equipment. Its characteristics make it ideal for protecting against fast voltage transients such as switching of transformers and inductors. The MOV also exhibits excellent thermal stability even in high temperature environments. Additionally, its low capacitance helps maintain low EMI levels, making it ideal for use in sensitive systems.

In terms of its working principle, the V68ZA20PX2855 acts as a short circuit during a high-voltage transient. When exposed to a voltage surge, the MOV quickly reduces its resistance to near zero, allowing the surge current to be diverted from the sensitive components that need protection. The MOV also acts as a clamp, allowing the current to pass through the varistor only when the voltage exceeds its ratings. The MOV helps protect sensitive circuit components from voltage transients and, in turn, can help to prevent the breakdown of the circuit.

In its most basic form, The V68ZA20PX2855 is a varistor device that helps protect electronic and electrical systems from voltage transients. It is designed to have high resistance to transients, allowing it to reduce its resistance to almost zero when exposed to a surge. Additionally, the MOV serves as a protective clamp at high voltages, allowing the current to pass through the varistor only when its ratings are exceeded. It is typically used in applications that require personnel safety and is well-suited for high-frequency current surges. The high current rating and low capacitance of the component also make it ideal for use in sensitive circuits.
