CDLL4910A

CDLL4910A application field and working principle

The CDLL4910A from Diodes Incorporated is a Zener Diode with extremely low leakage current in a single package. It features a low Zener voltage of 1.3V, a power dissipation of 500mW, and a high ln junction voltage of 81V. Additionally, its small size and excellent reliability make it ideal for numerous applications.

Working Principle

The CDLL4910A is an avalanche diode, which is a type of diode that operates by using an avalanche breakdown that occurs at a relatively high reverse voltage. When the reverse voltage applied exceeds the Zener breakdown of the diode, current begins to flow through the diode. The Zener breakdown voltage is dependent on the junction temperature, so as the temperature of the junction increases, the breakdown voltage also increases. It is this breakdown voltage that sets the ln junction voltage of the diode, which can range from 82V to 87V depending on the temperature of the junction.

Application Field

The CDLL4910A is ideal for use in telecommunications and power applications, as well as in many industrial and commercial applications. It can be used as a protective device in AC-DC power supplies, voltage regulators, overvoltage protection circuits, RF amplifiers, and LED lighting. Furthermore, it can be used as a clamping device in electronic circuits, voltage comparators, and voltage limiters. Additionally, the low leakage current and excellent reliability make it suitable for use in automotive applications.

In summary, the CDLL4910A from Diodes Incorporated is an ideal solution for a variety of applications due to its low Zener voltage of 1.3V, power dissipation of 500mW, and high ln junction voltage of 81V. Additionally, its small size and excellent reliability make it an ideal fit for applications in telecommunications, power, and automotive industries.
