CDLL5928B is a type of single Zener diode and is suitable for a variety of applications that demand precision voltage regulation or shunting. With a low voltage, high reverse current and low reverse leakage, it is an ideal choice for power supply applications. This article will focus on the application field and working principle of CDLL5928B.

Application Field of CDLL5928B

CDLL5928B is used mainly in the power supply industry, and specifically is suitable for voltage regulation and shunting. It\'s typically used in shunt voltage applications, and also in applications involving a minimum voltage redistribution, such as secondary battery systems, charge and discharge controls. Most notably, it can be used for low supply reverse current protection, eliminating the need for an external resistor to limit the incoming current.

Moreover, the wide range of breakover voltages, ESD tolerance and low leakage current also make CDLL5928B a great choice for RC/LED/coupling and suppression circuits, AC/DC adapters, switching power supplies, laptop and notebook power regulation, and microcontrollers.

Working Principle of CDLL5928B

CDLL5928B is made up of a single body containing a PN junction, plus two metal contacts which are connected to an anode and cathode. When there is a reverse voltage, current passes through the junction in a reverse direction, which causes a voltage drop at the junction due to the PN junction\'s internal resistance. This voltage drop is known as the zener voltage, which is adjustable by altering the device\'s temperature, doping and carrier concentrations.

When the applied voltage exceeds the zener voltage, the additional voltage "falls through" the junction, limiting the voltage and current that reaches the anode. This feature makes the device ideal for managing power and preventing further damage due to overvoltage.

Conclusion

CDLL5928B is a single Zener diode which is suitable for a variety of applications that demand precision voltage regulation or shunting. It is used mainly in the power supply industry, and has a wide range of applications including reverse current protection, LED/coupling and suppression circuits, AC/DC adapters, switching power supplies, laptop and notebook power regulation and microcontrollers. The working principle is based on PN junction resistance, which causes a voltage drop at the junction, known as zener voltage. It is this zener voltage that prevents further damage due to overvoltage.
