CDLL5298

CDLL5298 belongs to the Single Zener diode category, a type of semiconductor device. It is composed of one p-n junction that is heavily doped so that it can offer a less than 3.2V zener voltage even at a forward voltage drop of between 200 mV and 400 mV. These devices are widely used in a wide range of applications.

Application Field

CDLL5298 is mainly used for voltage regulation and noise reduction, as it can efficiently reduce useless noise from a circuit. Moreover, it is used in flip-flops, sample-hold circuits, and other switching circuits for precision pulse width modulation. It is especially suitable for frequent switching applications because it ensures accurate propagation delay time. In addition, it can be used for data protection against static electricity, static failure protection and line transient protection with 2.0V ± 0.2V and 0.9V ± 0.1V zener voltage (VZ). Furthermore, single zener diodes such as CDLL5298 provides line surge absorption and interference filtering among other uses.

Working Principle

When the zener diode works in the zener breakdown process, the current will flow allow the reverse voltage to increase rapidly and form a plateau in the static characteristic curve. When the external voltage is equal to or higher than the zener voltage (VZ), the current increases linearly. In other words, the output voltage on the circuit keeps constant and the voltage drop on the diode is practically zero. The Main reverse characteristic of CDLL5298 is stable and ensures a better accuracy representation, making it suitable for applications with frequent switching.

The reason for the stability of the device is that the zener breakdown voltage is strictly controlled by the zener voltage. When the reverse voltage applied to the zenier diode is slightly higher than the zener breakdown voltage, the diode current will increase rapidly and the power consumption will also increase. The zener diode can also decrease the forward voltage of the diode. Therefore, it can increase the operation efficiency of the circuit and reduce unnecessary heat dissipation in the operation process.

In addition, the characteristic of CDLL5298 can be changed by adding series resistance to the circuit. By increasing the resistance, the peak current of the circuit can be reduced, and the strain on the device can be minimized. This series resistance can also ensure that the device will not suddenly overtapped current which may cause the device to be damaged.

Conclusion

CDLL5298 is a Single Zener diode and is widely used in voltage regulation and noise reduction, line surge absorption, static failure and line transient protection, interference filtering, and precision pulse width modulation. It has a less than 3.2V zener voltage and a forward voltage drop of between 200 mV and 400 mV. It is a stable diode with a well-controlled zener breakdown voltage. The resistance can be set to control the peak current of the circuit.
