TVS (Transient Voltage Surge Suppressors) are electronic components designed to protect electrical systems, and other vulnerable circuits, from damage caused by voltage spikes, such as those caused by lightning or power surges. One popular type of TVS is the VE07M01150K Varistor, a non-linear voltage-dependent resistor whose resistance decreases with an increase in the voltage applied to it. This article will explain the application field and working principle of the VE07M01150K Varistor.

The VE07M01150K Varistor has a wide range of applications. It can be used to protect power supplies from lightning surges and to protect communication cables from electrostatic discharge (ESD). It can also be used to protect sensitive equipment from power line transient faults. It is commonly used in surge protectors and ESD protection devices in consumer electronics, such as computers, televisions, and mobile phones.

The working principle of the VE07M01150K Varistor is based on its non-linear voltage-dependent characteristics. When an AC surge is applied to the varistor, the voltage across it quickly rises. During this time, the resistance of the varistor decreases significantly. This decrease in resistance diverts much of the surge current away from the circuit, thus providing protection from overvoltage spikes. Once the surge has passed, the resistance of the varistor quickly returns to normal.

When selecting a VE07M01150K Varistor, it is important to consider the current rating, the maximum surge rating, the operating voltage, and the clamping voltage. The current rating of the varistor is determined by measuring the maximum current which can flow through the device without causing damage. The maximum surge rating refers to the maximum current which can flow through the varistor in a single spike. The operating voltage is the voltage at which the varistor will switch from low to high resistance, and clamping voltage is the maximum voltage that can be applied to the varistor without causing damage.

In conclusion, the VE07M01150K Varistor is a popular type of TVS used to protect circuits from voltage surges. It works by quickly reducing the resistance of the device, diverting most of the surge current away from the circuit. When selecting a VE07M01150K Varistor, it is important to consider factors such as the current rating, the maximum surge rating, the operating voltage, and the clamping voltage.
