Transient Voltage Suppressor (TVS) diodes are semiconductor devices designed to protect circuits and components from high-voltage transients. In particular, the LC100A is a forward-biased TVS diode with a breakdown voltage of 18 volts. It is used for taking surges of a single direction, and is most useful when the amplitude of the surge is higher than the LC100A’s breakdown voltage.

The LC100A provides surge protection for today\'s high-speed digital data lines, such as Ethernet, USB, IEEE-1394, and coaxial cables. It can be used in noise filter circuits and voltage division circuits, and can also be used to suppress induced high voltage transients.

The working principle of the LC100A is relatively simple. When the applied voltage exceeds the leakage breakdown voltage, the diode ‘clamps’ the voltage at its breakdown voltage. This enables the diode to block and absorb pulses of high energy, without continuous current flow. This kind of behavior is a desirable feature of the LC100A, as it helps keep the circuit from becoming unstable or overloaded due to surges.

Moreover, the LC100A can also be used to absorb ESD (Electrostatic Discharge). Electrostatic discharge occurs when two objects with different electrostatic potentials come into contact with each other. In this situation, the LC100A helps to protect the circuit from breakdown by absorbing the ESD before it can cause damage. It can be used to protect circuits with low turn-on voltages, such as digital logic gates.

To conclude, even though the LC100A application field is quite small, its working principle is quite versatile. It can be used against high-voltage transients, noise filter circuits, voltage division circuits, ESD, and digital logic gates. Thus, it is an important protective device for many of today\'s electronic circuits and devices.
