TVS (Transient Voltage Suppressors) devices, also known as Varistors, MOVs (Metal Oxide Varistors) are designed to be used in various kinds of circuits for surge and transient protection. The V140LU20CPX2855 belongs to the TVS - Varistors, MOVs family, and is a surface mount Varistor which protects against surges from the baseplate mounted terminal up to 2kV.

The V140LU20CPX2855 is a bidirectional surge current handling Varistor with four polarity configurations, and can be used in many applications. The device includes an integrated metal oxide varistor (MOV), a Light Emitting Diode (LED), and a fast-recovery diode (FRD). The device has a capacitance range of 0.010-20,000pF at 1V, and a rated voltage of 20V.

The device has a wide range of applications including EMI/RFI filters, transient suppression, and power distribution lines. In EMI/RFI filters, it is used to reduce unwanted power noise. The V140LU20CPX2855 can be used to protect circuits from transient voltage spikes and surges. It also can be used to protect power distribution lines, such as telephone lines, LAN cables, and automotive power lines.

The working principle of the V140LU20CPX2855 is quite simple. The MOV consists of two electrodes, one connected to the power supply and the other to the device’s terminal. When an overvoltage occurs, the MOV quickly absorbs the excess energy, dissipating the heat and protecting the device from any potential damage. A resistor or capacitor may also be used in combination with a MOV to achieve a more balanced energy protection. The LED indicator allows the user to check for correct functioning of the device.

In conclusion, the V140LU20CPX2855 is a much sought after, reliable, and cost-effective Varistor, and is the ideal solution for surge and transient protection. It is used in a vast variety of applications, such as EMI/RFI filters, power distribution lines, and transient suppression. It is also very easy to use, with a simple working principle involving the use of MOVs to absorb excess energy. The LED indicator gives users the assurance that the device is functioning correctly.
