TVS - Varistors, MOVs, is specifically for the protection of the circuit products, it can effectively stop static or sudden high-voltage interference and reduce damage to systems and electronic components. The V07P460L2T is one of the models of such products, which can be used in different types of applications. This article is going to discuss the application field and working principle of the V07P460L2T.

Application field ofV07P460L2T

The V07P460L2T belongs to the V Series Varistor Family from AOI, which is mainly designed for applications that require higher current capability and peak overload protection of electronic systems. The main performance characteristics of this device include wide range of of operating voltages and transients, wide temperature range of -40°C to 125°C, high arc suppression of up to 3.5kA, and surge absorption capacity of up to 20kA. It’s specially used for automotive applications, such as engine control, navigation systems, airbag, vehicle safety system, etc. It’s also widely used in industrial applications, including smart grid, solar panels, distribution line protection, UPS, welding applications, etc. In IT and consumer electronic products, it can provide surge protection in input circuits, protect communication lines, and also partially protect the output circuits in power supply systems.

Working principle of V07P460L2T

The V07P460L2T is mainly composed of a zinc oxide varistor element. The zinc oxide can change its impedance under the influence of electric field, so that it can efficiently absorb the surge voltage of the input signal. Varistor’s nonlinear resistance in the direct current will increase significantly when the inverse voltage is increased to a certain amplitude. When the surge voltage or electric field is generated, the varistor can reduce its resistance and suppress the over-voltage, so as to protect against over-voltage. The working principle is as follows: when the external surge voltage is generated, the varistor will have a rapid voltage drop from an open circuit to a short circuit, thereby absorbing the over-voltage energy into heat energy to protect the circuit and its components. This device has high impedance, fast response time, and low capacitance, which is necessary to protect automotive electronic systems from power supply transients, transients caused by electromagnetic interference, and other surges.

In summary, the V07P460L2T is a TVS – Varistors, MOVs used to protect the circuit and its components from over-voltage. It has wide range of operating voltage and temperature and can absorb up to 20kA of surge current. It’s mainly used for automotive applications, industrial applications, IT and consumer electronics products. The fundamental working principle of the V07P460L2T is that the varistor can reduce its resistance, absorbs the surge voltage and protect against over-voltage by changing its impedance under the influence of electric field.
