TVS (Transient Voltage Suppressors) is a kind of voltage-dependent protection components which are widely used to protect circuits from over-voltage and over-temperature. Among them, Varistors and MOVs (Metal Oxide Varistors) are the two most widely used types. V131DB40 is a kind of MOVs with its application fields and working principle introduced in the following text.

The application fields of V131DB40 are mainly in the automatic control equipment, measuring and inspection equipment, electronic instrument, communication system, electronic toys, general-purpose consumer electronics, payment instrument, as well as other electronic equipment and appliances. It is mostly used to suppress high transient voltage generated by contact or direct lightning, such as sparks caused by switches or transmission lines. V131DB40 is also suitable for other general pulse overload protection and approach of overvoltage protection.

The working principle towards V131DB40 can be explained as follows. When it is not working, V131DB40 is an insulator with high impedance. With the increase of the external over-voltage, the electric field applied to V131DB40 will be stronger, increasing the electric current conducted through V131DB40. And then, V131DB40 will enter into the conduction state to protect the system from transient voltage surges or over-voltage. When the voltage or current returned to normal, V131DB40 also returned to the insulation state.

In order to meet different working conditions, V131DB40 has a wide voltage range varying from 22V to 250V. It also features high energy capacity and low leakage current, making it ideal for transient voltage protection and circuit protection. Besides, V131DB40 can be operated with a wide temperature range, providing reliable over-voltage protection in a variety of temperature and voltage environments.

In conclusion, V131DB40 is an ideal voltage-dependent protector within the application, such as automatic control equipment, measuring and inspection equipment, electronic instrument, communication system, and other electronic equipment and appliances. With its working principle and advantages, V131DB40 plays an important role to protect the circuited from over-voltage and over-temperature.
