Varistors, also known as varistors, are voltage-dependent resistors (VDRs). They are designed for very low resistance when a current flows though them. When the voltage exceeds a certain threshold, their resistance dramatically increases. When the voltage returns to the threshold value, their resistance returns to the lower value. In other words, they operate with two distinct ranges of resistance values.

The V480LS40APX2855 is a transient voltage suppression diode (TVS). It is a three-terminal device with an anode, cathode, and gate connected in series. It provides overvoltage protection from damaging transient voltages of up to 2855 volts. This device is designed for semiconductor protection, mostly in AC/DC converters. It acts as an open switch when the voltage is exceeded and limits the current that passes through it.

The working principle of V480LS40APX2855 can be broadly divided into two phases. The first phase is stand-by mode where the device does not actively interact with the circuit. It will remain in this mode until the voltage exceeds the breakdown level. Once the voltage exceeds the breakdown level, it enters the tracking performance phase.

In the tracking phase, V480LS40APX2855 continuously monitors the circuit and responds to any changes in the input voltage. During this phase, the device is constantly adjusting the current that passes through it in order to maintain the voltage within safe limits. It has a response time of 0.2 μsec and a peak surge handling capacity of 40A. This makes the V480LS40APX2855 suitable for high-frequency ac/dc converter applications.

The application field of the V480LS40APX2855 is mainly in the protection of precision electronics in AC/DC converters. It is widely used in small electronic devices such as cell phones, computers, radios, and medical equipment. This device offers very reliable protection from damaging transients and is designed to protect precision electronics from short-term and long-term damage. With a protection rating of 2855 volts, it can withstand wide fluctuations in the input voltage.

In conclusion, the V480LS40APX2855 is a three-terminal transient voltage suppressor (TVS) designed for semiconductor protection. It can handle up to 40A of peak surge current and has a protection rating of 2855 volts. It has a low response time of 0.2 μsec and is suitable for high-frequency ac/dc converter applications. V480LS40APX2855 is used to protect precision electronics in many small electronic devices.
