Diodes – Zener – Single

The CDLL5239B is a Zener single (1) diode manufactured and sold by STMicroelectronics. It has a breakdown voltage of 5.5V, a maximum peak repetitive reverse voltage of 60V, and an average forward current at an ambient temperature of 25°C of 1.1A. In terms of energy, the CDLL5239B has an average power dissipation of 1.3 watts.

Application Fields of the CDLL5239B

The CDLL5239B is used in a variety of applications, including power management, energy harvesting, motor control, and audio protection. As a Zener diode, the CDLL5239B is used to protect circuits from spikes in voltage or activate other components at a certain voltage. It can also be used as a voltage regulator in electronic systems.

Working Principle of the CDLL5239B

The CDLL5239B works by allowing current to pass through it when a certain voltage is reached. At this point, the Zener diode is said to "breakdown," and current begins to flow across its two terminals. The CDLL5239B has the ability to limit the voltage to the breakdown point, providing noise protection. The diode also has the ability to automatically adjust its forward current to maintain the reverse voltage at the breakdown point.

When a voltage higher than the breakdown voltage is applied to the CDLL5239B, it acts as a normal diode and prevents the flow of current. This is due to the Zener effect, which increases the normal reverse blocking capability of the diode. As such, the CDLL5239B can provide voltage regulation for a wide range of voltages.

In addition, the CDLL5239B also provides noise protection. When connected across a circuit, it limits the voltage to the breakdown point, providing shielding from voltage spikes. This makes the diode an ideal choice for audio protection in sensitive circuits.

The CDLL5239B is a Zener single diode with a wide variety of applications in various fields. It is used to protect circuits from voltage spikes, safely regulate voltage, and provide audio protection. It works by allowing current to flow through it when a certain voltage is reached and has the ability to limit the voltage to the breakdown point.
