TVS – Varistors, MOVs are very important suppression components to protect both the device and the system from various external influences. One type is V680LU100CP. It is specifically designed to protect against transient voltage that could cause damage or disturbance to devices like embedded microprocessor systems, communications systems, automotive electronics, and AC and DC power systems. Its structure and working principle are discussed in this paper.

V680LU100CP is a high-performance Varistor (also known as Transient Voltage Suppressor). It is a nonlinear circuit protection element. It consists of a metal oxide, hence MOV, like zinc oxide (ZnO) and filled in an epoxy resin package. From its structure, it can be seen that V680LU100CP consists of a casing, two leads and a densely packed disc. The casing is commonly made of thermoplastic epoxy resin, the leads are of thick metal and the disc is made of an oxide material such as zinc oxide. This package helps to protect the transient suppressor from dust, water and also increases its reliability and durability.

The working principle of V680LU100CP is relatively simple. When a transient voltage with an amplitude of about 100 volts is applied to it, a metal-oxide barrier (MOA) is formed on the surface of the zinc oxide material, which is mainly responsible for suppressing the transient voltage. The MOA then absorbs the energy of the transient voltage, dissipating it and thus protecting the device from voltage spikes. Additionally, the high capacitance of the zinc oxide material helps to reduce the rise time of the transient voltage and the reaction time of the component.

The main application areas of the V680LU100CP are embedded microprocessor systems, communications systems, and AC and DC power systems. In embedded microprocessor systems, the V680LU100CP is used to protect the processor from high voltage transient, which can be caused by ESD events, electrostatic inductions, bonding wire inductions etc. In communications systems, the V680LU100CP provides protection against electromagnetic interference (EMI). This is especially important in mobile applications as they are subjected to higher levels of EMI radiation. In AC and DC power systems, V680LU100CP provides surge protection. It can help to block excessive voltage spikes that can cause damage to the components in the system.

To conclude, V680LU100CP is a high-performance Varistor designed to protect against transient voltage that could cause damage or disturbance to devices like embedded microprocessors, communications systems, automotive electronics, and AC and DC power systems. It has a relatively simple structure and principle, and is capable of suppressing transient voltage with an amplitude of about 100 volts. Its application field is mainly in embedded microprocessor systems, communications systems, and AC and DC power systems. In these systems, it provides protection from transient voltages, EMC radiation, and voltage spikes.
