TVS Varistors, MOVs and 87063-022 Application Field and Working Principle

TVS (transient voltage suppressors) are devices used to protect circuits from damaging or overvoltage events by dissipating the excess energy from the voltage transient. This type of circuit protection device can be used to protect both low-voltage circuits, such as computers, phones, and other devices, and high-voltage circuits, such as those found in manufacturing and power systems. TVS devices are also used in military and aerospace applications due to the extreme stability that TVS-based circuit protection provides.

MOVs (metal oxide varistors) are one of the most commonly used circuit protection devices due to their robustness and reliability. MOVs are formed by pressing a mixture of metal oxide powders into a disc shape. A metal oxide film is then electro-chemically deposited over the disc to further increase its ability to dissipate energy and conduct electric current. This combination provides a high level of energy absorption, making MOVs reliable and effective at suppressing transients.

87063-022 is a type of MOV device that is designed to protect against lightning strikes, power surges, and static electricity. Its working principle is simple and effective. When the voltage across the MOV exceeds its threshold, it will conduct current from the input source to ground, thus dissipating the energy from the transient and protecting the connected circuit.

The 87063-022 MOV is most effective when used in high-impedance and high-voltage applications with fast voltage transitions, as it is able to quickly respond to these transients. It is also capable of operating in extreme temperatures and corrosive environments, making it an ideal choice for applications both indoors and outdoors. Furthermore, the 87063-022 MOV is certified by Underwriters Laboratories, which makes it a reliable and safe choice for industrial and commercial applications.

In order to maximize its effectiveness, the 87063-022 MOV should be paired with other components, such as a capacitor and a diode, which reduce the amount of voltage that is transferred to the MOV and its threshold. This combination helps to ensure that the MOV is more resistant to false triggering, while still being able to protect the connected circuit.

In conclusion, the 87063-022 MOV is a reliable and effective choice for protecting high-impedance and high-voltage applications. It is a robust and reliable device that can operate in extreme temperatures and corrosive environments. Furthermore, it is certified by Underwriters Laboratories, making it an ideal choice for commercial and industrial applications.
