Diodes - Zener - Single

The CDLL4467 is a popular model of diode in the Zener Diode family. It is widely used for applications that require the suppression or regulation of high voltage. In a Zener Diode, a Zener voltage is applied across the diode and the voltage across the diode is kept at that level regardless of the current. This feature makes the Zener Diode ideal for applications where a continuous and stable voltage is required.The CDLL4467 offers a higher power handling capacity as compared to other models in the same family and allows for higher current handling capacity. It usually has a total power dissipation of 0.25W and has excellent surge capabilities. The breakdown voltage of this device is typically between 4.3 to 6.7V. This makes the CDLL4467 ideal for applications requiring low zener voltages.The CDLL4467 can be used as a voltage regulator in an AC/DC and DC/DC converter system. It can be used to regulate an input voltage or to reduce an output voltage. The Zener breakdown voltage will remain stable and will not be affected by the supply voltage or the load current. The CDLL4467 is also used for reverse polarity protection and in LED lighting applications.The CDLL4467 is a monolithic Zener diode which features a symmetrical design consisting of two silicon chips placed back to back. The one on the front is connected to the cathode side and on the rear side there is a metal oxide layer protecting the diode from excessive temperature and voltage. The metal oxide layer reduces maximum current to a safe voltage and prevents overheating.The CDLL4467 also has a thermal protection mechanism that will shut down operation if the device overheats. This thermal protection will force the device to operate at a lower voltage and lower current, thereby reducing the risk of any potential damage.The CDLL4467 is especially useful in AC and DC converter applications. When used as a voltage regulator in a DC/DC converter, the current will be limited by the Zener voltage and the voltage will not exceed the reverse breakdown voltage. This ensures that the output voltage is always kept stable.Similarly, when used in an AC/DC converter, the CDLL4467 will regulate the input voltage so that the output voltage is kept within a certain range. The Zener voltage will limit the current during the power down sequence and regulate the output voltage, thus providing a high level of protection.In LED lighting applications, the CDLL4467 can be used to control the voltage in the LED circuit. The diode will regulate the voltage so that it does not exceed the rated current while still providing enough current to allow the LED to operate.The CDLL4467 is an ideal choice for applications that require low voltages and high current capabilities. The low breakdown voltage makes it well suited for applications that require low Zener voltages. The thermal protection and symmetric design help to provide maximum protection, thus making it a reliable and trusted option for applications that require voltage regulation and/or reverse polarity protection.
