V68ZA20PX10 Circuit Protection

The V68ZA20PX10 component is a form of protection device that falls into the broad categories of Transient Voltage Suppressors (TVS) and Metal Oxide Varistors (MOVs). It is designed to be a surge limiting tool when installed in electrical circuits and to provide a form of integrated circuit protection. The component is often used in medium- and high-power applications, both in AC and DC circuits. The component is designed to absorb transients, as opposed to providing a low-resistance path as does a fuse.

General Purpose of V68ZA20PX10

The V68ZA20PX10 is designed to protect electrical devices and components from voltage transients caused by lightning, electrical faults, or additional energy sources. The device is a semi-conductive, voltage-limiting electronic component that automatically conducts when the voltage exceeds its insulation strength. It also blocks the voltage in the reverse direction, providing a level of protection from overvoltages. Additionally, the device reduces noise and other interference to electrical circuits.

Construction of V68ZA20PX10

V68ZA20PX10 is a three-phase surge suppression component with each terminal labelled A, B, and C. The device fits in a two-or four-terminal cartridge that is soldered directly on a printed circuit board (PCB). The exterior of the device is packaged in an epoxy material that provides physical and environmental protection. Internally, the device consists of a ceramic plate covered with a thin layer of zinc oxide granules. The zinc oxide granules are then held in place by a pressure plate and held close to each other by misalignment screws.

Operation of V68ZA20PX10

In operation, the V68ZA20PX10 exhibits nonlinear, Zinc Oxide resistor behavior. When a voltage exceeding a certain threshold is applied to the component, a destructive electrostatic discharge (ESD) is created through the component. This discharge travels through the zinc oxide granules, providing a resistive voltage limit at the PCB. When the voltage is reduced below a certain level, the electrical discharge stops and the device returns to a high-impedance state.

Application Field of V68ZA20PX10

The V68ZA20PX10 is used to protect electrical equipment from voltage transients and other types of energy. It is commonly used in telecommunication systems, power supplies, and lighting fixtures. Additionally, it is extensively used in power meters, electronic controls, gaming machines, and computer systems. The device can also be used in industrial and automotive applications that require radiation protection.

Advantages of V68ZA20PX10

The V68ZA20PX10 offers several advantages. First, the device is relatively compact, making it easy to install in tight spaces. Additionally, the device is designed to be effective over a wide range of temperatures, making it suitable for difficult environmental conditions. Another benefit is that the device can dissipate a large amount of energy, protecting electrical circuits from being damaged. Finally, since the device is constructed from zinc oxide, it can handle large voltages and currents efficiently.

Conclusion

The V68ZA20PX10 is a three-phase surge suppression component that falls into the TVS and MOV categories. The device is commonly used in a variety of medium- to high-power applications and is designed to provide integrated circuit protection. The device is designed to absorb transients that could damage electrical circuits, and it is compact and easy to install. Additionally, the V68ZA20PX10 offers a number of advantages, such as wide temperature range, dissipates a large amount of energy, and it is constructed from zinc oxide. In summary, the V68ZA20PX10 is an effective protection device for many applications.
