The CG0402MLC-24LG is one type of TVS (Transient Voltage Suppressors) that is used to protect circuits against electrostatic discharge and other over-voltage transients. It is also known as a Varistor or a MOV (Metal Oxide Varistor).

When an electrical circuit is exposed to transients, it can become vulnerable to damage due to the sudden surge in voltage. A TVS is designed to provide protection against these voltage transients by quickly limiting the voltage that can be applied to the protected circuit. In comparison, MOVs provide a more gradual voltage reduction, beginning at the moment the voltage rises above the MOV\'s rated protection level.

The CG0402MLC-24LG is a small component, measuring only 4 x 2 mm in size. It is a lower capacitance silicon-based varistor which has a rated breakdown voltage of 24 volts. It is designed for use in low voltage, low to medium frequency application fields such as ASL (Alternative Signal Level) signal protection, and also for SMPS (Switched Mode Power Supply) protection.

The CG0402MLC-24LG provides excellent ESD protection, with its silicon construction allowing for greater protection than metal oxide MOVs which are usually limited to the values of 10 to 25V. This makes it an excellent choice for protecting sensitive devices that require higher breakdown voltages without sacrificing reliability.

The working principle of the CG0402MLC-24LG is based on the PN junction theory. When a voltage higher than the breakdown voltage is applied to the MOV, electrons and holes understand each other at an interface, creating an electric field which protects the circuit. The CG0402MLC-24LG has ultra-low capacitance, meaning it offers maximum protection with minimal interference.

In summary, the CG0402MLC-24LG is an excellent choice for low-voltage applications where high reliability and superior ESD protection are needed. Its small size and ultra-low capacitance make it an ideal choice for protecting sensitive circuits. It is also an ideal choice for ASL and SMPS protection due to its higher breakdown voltage rating.
