V680LT80AP application field and working principle

V680LT80AP is a type of Thyristor Surge Protective Device (TSPD) which is classified as a Transient Voltage Suppressor (TVS). It is most widely used in the power distribution sector to provide follow-up of transient events due to lightning, industrial power transients, and other sources of electrical transients. It belongs to the family of Voltage Dependent Protectors (VDPs) that are used to protect against overvoltage and electromechanical failure.

A TVS is a voltage-dependent device that is specifically designed to regulate voltage by clamping it to a threshold level. The threshold level is referred to as the protection voltage. In order to activate the protection of the TVS, a voltage greater than the protection voltage is needed. When the applied voltage exceeds the protection voltage of the TVS, the device will trigger and clamp the voltage to the protection voltage.

In the case of V680LT80AP, it is a bi-directional device which can protect against both ESD (electrostatic discharge) and surges. It has a protection voltage range between 5V and 330V, and can absorb up to 500A 8/20us for proper protection. The device is also designed to be Surface-mountable, thus it is able to withstand a high temperature of 145°C. Furthermore, it is compliant to both UL and IEC standards.

The operation of the device is quite simple and straight-forward. When applied with a voltage higher than the protection voltage set point, the device will conduct until the voltage is brought back to the protection voltage. The device should be properly selected based on the application’s needs. Different applications will require different protection levels. Therefore, the device should be chosen accordingly.

In conclusion, V680LT80AP is a versatile TVS device designed to protect against ESD and surges. It is a bi-directional device with a range of voltages from 5V to 330V and can withstand 500A 8/20us for proper protection. Moreover, it is a Surface-mountable device that is compliant to both UL and IEC standards.
