CDLL4764A is a single Zener diode designed for voltage regulation and over-voltage protection. This diode is designed to hold a constant voltage, regardless of changes in circuit conditions such as temperature and current. The CDLL4764A Zener diode is suitable for applications such as voltage regulation, over-voltage protection, and voltage reference.

The CDLL4764A is a low voltage zener diode with an operating current range of 10 mA to 100 mA. The voltage breakdown (Vz) of the CDLL4764A is 5 V. It is available in a SOD-323 package and comes in a variety of colours including green, yellow, and white.

Internally, the CDLL4764A consists of two diodes connected in parallel. One diode is a PN junction and the other is a Zener diode. The PN junction diode controls the current flowing through the circuit and the Zener diode controls the voltage applied to the circuit.

In operation, the PN junction diode allows current to flow into the circuit when the voltage reaches the forward break-down voltage. The Zener diode acts like a reverse break-down diode, allowing current to flow out of the circuit once the voltage reaches the Zener voltage.

The operation of the CDLL4764A is simple. When an input voltage of 5 V or more is applied to the circuit, the PN junction diode turns on and allows current to flow into the circuit. This current flows through the Zener diode, causing its voltage to drop.

Once the voltage across the Zener diode reaches its breakdown voltage (Vz), the Zener diode acts like a reverse break-down diode and allows current to flow out of the circuit. This keeps the voltage across the circuit constant, regardless of changes in circuit conditions such as temperature and current.

The most common application of the CDLL4764A is for voltage regulation and over-voltage protection. It can be used to regulate a variety of voltages, including 5 V, 3.3 V, and 2.5 V. It can also be used to provide over-voltage protection by limiting the voltage applied to a circuit to the Zener voltage.

The CDLL4764A can also be used as a voltage reference. By connecting the Zener diode to a load resistor, it can be used to create a reference voltage that can be used to measure other voltages.

The CDLL4764A is a versatile and widely used Zener diode designed for voltage regulation and over-voltage protection. With its simple operating principle, it can be used for a variety of purposes, from voltage regulation to over-voltage protection to voltage reference. It is available in a SOD-323 package and comes in a variety of colors, making it suited for a wide range of applications.
