TVS diodes, sometimes referred to as transil diodes, are a form of special order diode used to prevent high voltages from passing through electrical systems. These devices are often used in products such as automotive applications, medical PET imaging, military products, communications, digital circuitry, and computer motherboards, to protect against high voltage electrical transients. The CDNBS08-SRDA12-4 is one type of TVS diode, and is typically used for telecommunications applications.

A TVS diode is an over-voltage protection device used in electronic circuits. This type of diode is designed to tolerate high voltage and its low breakdown voltage (VBR) makes it an ideal choice to protect sensitive electronic devices from electrical transients. The CDNBS08-SRDA12-4 is a specialized type of TVS diode designed for high speed communication. This type of diode uses a unique stabilized reverse avalanche structure to provide both over-voltage and transient protection.

The working principle of the CDNBS08-SRDA12-4 TVS diode is based on the principle of reverse avalanche breakdown. In a reverse avalanche breakdown, a strong electric field is applied to the diode, and this causes electrons to be accelerated in the reverse direction, resulting in a high current flow. When this current reaches a certain level, it triggers a breakdown of the PN junction, resulting in a large current surge. The CDNBS08-SRDA12-4 is designed to be able to withstand this surge by using a combination of a varistor and a zener diode. The varistor is used to absorb the excess energy, while the zener diode limits the surge current until it reaches a safe level.

The CDNBS08-SRDA12-4 is usually used in telecommunication applications such as DSL lines, Ethernet cables, and cellular telephones. It is used to protect signal lines from voltage transients, caused by lightning and other electrical disturbances. When such a transient occurs, it is often necessary to protect these lines from destruction, as these lines can carry valuable data that is important for communication. The CDNBS08-SRDA12-4 is designed to provide this protection in the form of an absorbing spike of current.

The CDNBS08-SRDA12-4 also has an extended temperature range, allowing it to be used in more demanding applications such as automotive systems. It is also designed to meet the requirements of the ASTM-F547-95 standard, which requires that the device be able to absorb up to 1000 volts with a surge current of up to 1.5 amperes. In addition, the device can withstand up to 10KV of ESD protection.

In summary, the CDNBS08-SRDA12-4 is an over-voltage protection device used in telecommunication applications. It has a specialized stabilized reverse avalanche structure which provides an effective over-voltage and transient protection. The device is designed to withstand up to 1000 volts with a surge current of up to 1.5 amperes, and is also capable of withstanding up to 10KV of ESD protection. The extended temperature range and compatibility with the ASTM-F547-95 standard make the CDNBS08-SRDA12-4 an ideal choice for a variety of applications.
