Diodes - Zener - Single

CDLL4479 is a single zener diode which is widely used in the electronics industry. A zener diode is a semiconductor diode that permits current to flow not only from its anode to cathode, but also in the reverse direction when the voltage is above a certain value called the "breakdown voltage" or "zener voltage".

Application Field

The CDLL4479 is a popular choice for applications that require low power consumption and a stable voltage reference. It is often used in battery-powered applications, such as laptop computers and mobile devices, to regulate the battery voltage. It may also be used in power supplies, voltage multipliers, and voltage regulators. Additionally, the CDLL4479 can be utilized in AC/DC converters, DC/DC converters, UPS power systems, and automotive applications.

Working Principle

The CDLL4479 works by utilizing a zener diode to maintain a stable voltage across its terminals, regardless of current flow. When a voltage greater than the specified breakdown voltage is applied to the anode, current flows from the anode to the cathode, creating a “zener” effect and producing a stable voltage. This voltage is independent of the current flowing through the diode.

The CDLL4479 is a low voltage zener diode. It has a low power dissipation rating, which means it can be used in low power applications without the need for a heatsink. It also has a temperature coefficient of 0.05% per degree Celsius, which helps provide a stable voltage reference over varying temperatures.

The CDLL4479 is very reliable and is able to handle high surge current levels. It has a high stability over time and temperature, making it suitable for long-term applications. It has a low forward voltage drop and a high reverse breakdown voltage, allowing it to work in a wide variety of applications.

Conclusion

In conclusion, the CDLL4479 is a very popular single zener diode. It is often used in battery-powered applications, such as laptop computers and mobile devices, to regulate the battery voltage. It can also be used in power supplies, voltage multipliers, and voltage regulators. The CDLL4479 is very reliable and can handle high surge current levels. Additionally, it has a low power dissipation rating, which makes it suitable for low power applications. With its high stability over time and temperature, it is the perfect choice for long-term applications.
