The VCAS Series Varistors are nonlinear components that protect circuits against surges many times greater than their orientation voltage. The VCAS121060J121DP Varistor is a component well suited to a variety of circuit protection needs. This article will take a look at the applications fields and working principle of the VCSA121060J121DP Varistor.

Application Fields

The VCAS121060J121DP has a variety of uses in the protection of electrical and electronic circuits. It is useful for protecting power supplies and other circuits against transient voltage spikes. It is a suitable choice for both industrial and consumer electronics. It is also effective in protecting lightning-induced surges and is commonly used in the automotive industry to protect automobile CD players and other sensitive electronic components. Additionally, it can be used to protect AC mains line and lighting circuits. It has a variety of applications in combining lightning and surge protection.

Working Principle

The VCAS121060J121DP Varistor is made with a ceramic body and a multilayer system. It is composed of a conductive metal oxide layer, a dielectric layer, and an electrode. The metal oxide layer is composed of zinc oxide and other metals. It has two main modes of working: the first is the “closure” mode, in which the Varistor moves the electric current from the “top” to the “bottom” of the electrode. The second mode of working is the “open” mode, in which the Varistor moves the electric current from the “bottom” to the “top” of the electrode. The two modes are complementary and allow the Varistor to act as a surge protection device, absorbing the voltage spike and dissipating it safely.

The working principal can be further described as an electric discharge of the protection network. When the voltage surpasses the orientation voltage, the Varistor will start to conduct current. The current will then be spread in the metal oxide layer. When the current drops, the Varistor will stop conducting current, and the voltage will become equal to the orientation voltage. The perforations in the Varistor allow it to absorb high-energy pulses, such as lightning strikes, without damage.

Conclusion

The VCAS121060J121DP Varistor is a versatile component that can be used in a variety of applications to protect circuits from transient voltage spikes and surges. Its multilayer system allows for efficient protection. It is well suited to industrial and consumer applications, as well as automotive and lighting circuits. The working principle is based on the electric discharge of the protection network and allows for safe absorption of high-energy pulses.
