TVS - Diodes are devices that use trigger voltage to protect electronic circuits from the damage of overvoltage. They are designed to suppress and divert excessive surge or voltage spikes from entering sensitive circuits. The 1N8168 is a television surge suppressor diode designed to protect sensitive electronic equipment from transient overvoltage that may occur on long cable runs.

This device has a simple structure which consists of an anode, a cathode and a zener diode. The 1N8168 is available in many forms including the SMA, DO-214AC, and SMB versions. These diodes are designed to withstand large surge current up to 6500 Amps, and provide reliable voltage noise protection of up to 7 volts.

The application of the 1N8168 is mainly in low voltage distribution systems where it is used to provide surge protection from lightning induced overvoltages which could cause physical property damage to equipment and systems. The 1N8168 is also used in telecommunications, satellite, and power supplies where it can protect against power transients. The device is also commonly used in consumer electronics, audio, and video equipment.

The working principle of the 1N8168 is based on the zener diode\'s operation. When the external surge voltage exceeds the breakdown voltage, the diode will conduct. This triggers a conduction of electrons between the anode and the cathode, which in turn dissipates the surge energy, preventing any further damage from occurring. Once the transient is over, the surge current is diverted by the zener diode, allowing it to switch off automatically.

The 1N8168 is able to efficiently handle a variety of transient surges, including fast transients, slow transients, minor overvoltage peaks, and any other situation where high current needs to be diverted quickly. The device is also highly reliable and able to perform under extreme temperatures, making it a great choice for noise protection in industrial and commercial settings.

In summary, the 1N8168 is an economical and robust surge protection diode designed to protect sensitive electronics from overvoltage and transient surges. Its simple construction and reliable performance make it a great choice for noise protection in a wide variety of applications.
