2DC79SBR-A197 is a type of two-diode electronic device that can be used for various applications. It consists of two diodes, one of which is a stabilized avalanche diode with reverse voltage protection, and the other can be an avalanche diode with or without reverse polarity. The 2DC79SBR-A197 device is typically used for protection against power surges in critical parts of an electronic system, such as a PC or laptop power supply or a hard drive.

The primary application of the 2DC79SBR-A197 is in the form of transient voltage surge suppression (TVSS). TVSS devices are used in many electronic designs to protect against the instantaneous voltage spikes caused by lightning strikes or other short-term energy discharges. This type of device is also often used in industrial control systems to provide overvoltage protection and reduce the risk of component damage from electrical surges.

The working principle of the 2DC79SBR-A197 device is to provide protection against transient overvoltages by clamping or suppressing the electrical voltage. The device consists of two diodes, one of which is a zener diode, and the other is an avalanche diode. The zener diode is used to provide a reference voltage that is lower than the peak-to-peak voltage of the surges, while the avalanche diode is used to shunt the excess energy away from the protected circuits. The two diodes act together to provide fast, effective protection against voltage surges.

When an overvoltage event occurs, the zener diode begins to conduct electricity and the avalanche diode acts as a switch to quickly divert the current away from the protected circuits. The avalanche diode allows the voltage to decrease until it falls below the established threshold, at which point the two diodes turn off and the protected circuit is no longer at risk from the overvoltage.

The 2DC79SBR-A197 device is typically used in consumer electronics, industrial systems, and power supplies. It is often found in computers, LCD monitors, TV sets, fax machines, and AC/DC power adaptors. The device is designed to be highly reliable and provide superior performance when it comes to providing surge protection for sensitive electronic components.

The 2DC79SBR-A197 device is a reliable and cost-effective solution for providing overvoltage protection in a wide range of applications. The device is easy to install and is designed to offer superior performance and reliability for a wide range of electrical protection needs.
