CDLL4924

Diodes - Zener - Single

CDLL4924 is a Single Zener Diode from the CODLL series. It has a voltage rating of 3.9V with its power dissipation capabilities of 500 mW. This diode is offered in standard DO-34 package of a hermetically sealed glass body type. It is manufactured by a semiconductor specialty company called CDeemet, and has been designed to protect sensitive devices and components from overvoltage. CDLL4924 can also be used in applications such as Voltage Regulation, Suppression and Adaptation, Voltage Reference, Level Control and Signal Clamping.

Application Field

The CDLL4924 can be used in a variety of circuit applications such as power supplies, servo motors, appliances, measuring instruments, automotive and communications technology. This Zener diode can be used as a power supply regulator, or to provide an adjustable DC voltage with very low noise. In automotive applications, the CDLL4924 is often used to provide drive power to various vehicle systems, and the overvoltage protection feature ensures the safety of other components.

Working Principle

The CDLL4924 acts as a voltage regulator by utilizing the Zener breakdown voltage principle. It consists of a Zener diode configured in its reverse-biased state connected in series with a variable resistor. The Zener breakdown voltage is determined by the difference between the resistor value and the breakdown voltage of the Zener diode. The Zener breakdown voltage serves as a clamping point and any variation in the input voltage will not be allowed to pass beyond this voltage. The resistor value is thereby adjusted to maintain the output voltage at a constant level.

Conclusion

The CDLL4924 is an excellent solution for applications that require overvoltage protection, or require an adjustable DC voltage source with very low noise. Its hermetically sealed glass body type makes it ideal for the harsh environmental conditions of the modern automotive and communications systems. Its Zener breakdown voltage-based operating principle ensures that any fluctuation in the input voltage will not pass beyond the set voltage value. Thus, it provides protection for other vulnerable components in a circuit system.
