CDLL971B Application Field and Working Principle

CDLL971B is a type of diode in the Single Zener family. It is a low-power, low-saturation, high-precision, low-voltage Zener diode with a single-phase regulator circuit. It provides high reliability and accurate, repeatable performance. The device is rated for a maximum power dissipation of 5mW and a reverse breakdown voltage of 6.8V.

Design and Construction

The CDLL971B is constructed of a single Zener diode in a small, horizontally mounted SOD-805 package. The device has three leads, with the center lead being the anode and the two outermost leads being the cathodes. The anode lead is designed as a cathode-connected diode, while the cathode lead is arranged in a two-phase P-type structure. This arrangement ensures that the device operates with a low power dissipation and low-voltage breakdown voltage.

Operation

The CDLL971B operates by allowing a current to flow when the device is forward-biased and subsequently diverting the current to ground when the device is reverse-biased. The forward-biased current is limited to 5mA, which keeps the device operating with low power dissipation. The reverse-biased current is limited to 6.8V, ensuring the device operates in a low-voltage, high-accuracy environment.

Applications

The CDLL971B is a low-power, low-saturation, high-precision Zener diode with a wide range of applications. The device is ideal for applications that require a low-voltage breakdown voltage and high reliability. The device is commonly used in voltage stabilization, voltage limiting, and ESD suppression circuits and is also featured in many general-purpose diode circuits. Other applications include LED drivers, voltage regulators, power managers, and AC/DC converters.

Conclusion

CDLL971B is a single Zener diode specifically designed for low-power and low-saturation applications. It is capable of delivering reliable, repeatable performance and is rated for a reverse breakdown voltage of 6.8V. The device is ideally suited for voltage stabilization, voltage limiting, ESD suppression, and other general-purpose diode applications.
