CDLL5929B Application Field and Working Principle

Diodes, often referred to as rectifiers, are electronic devices used to convert alternating current (AC) into direct current (DC). Zener diodes are particular type of diode that allow energy to flow in both directions and regulate voltage within a certain level. The CDLL5929B series are 400mW surface mount Zener diodes with excellent high temperature stability from -55°C to +175°C.

Application Field

The CDLL5929B series are designed for applications where high temperature stability is required. This includes industrial electronics, automotive, etc. Because of the numerous advantages of surface mount technology, the CDLL5929B series is suitable for use in surface mount printed circuit boards (PCB).

Working Principle

At normal working conditions, the diode is a reverse-biased junction and no current flows through it. With an increasing voltage level, the current will increase when the reverse bias voltage reaches the Zener voltage VZ. The salient feature of the CDLL5929B series is its temperature independent, reverse blocking voltage and its low power consumption.The diode possesses a single p-n junction, mounted between two electrodes. As the reverse bias voltage increases, the current flows when it reaches the knee voltage VZ. When this happens, the diode creates a low voltage drop, allowing it to act as an ideal regulator, limiting the output voltage to a specified level. In addition to its use as a voltage regulator, the CDLL5929B series is also suitable for protection circuits and voltage clamping applications due to its excellent high temperature stability. The diode has a reverse current sharing capability and is suitable for use in both series and parallel connections.

Conclusion

The CDLL5929B series are 400mW surface mount Zener diodes with excellent high temperature stability from -55°C to +175°C. These diodes are designed for applications where high temperature stability is required, such as industrial electronics and automotive. The diode creates a low voltage drop, allowing it to act as an ideal regulator, limiting the output voltage to a specified level. In addition to its use as a voltage regulator, the CDLL5929B series is also suitable for protection circuits and voltage clamping applications due to its excellent high temperature stability.
