CDLL4688 application field and working principle

The CDLL4688 diode is a Zener diode known as a single type diode and is well suited for applications in a wide range of fields. Such applications include power rectification, voltage regulation and protection circuits. In this article, we take a closer look at the application fields and working principle of a CDLL4688 single type diode.

Application fields

The CDLL4688 single type diode is suitable for use in a wide range of applications. It is often used as a power rectification and voltage regulation device in power supply design. It can also be used in protection circuits, such as overvoltage protection, reverse blocking and transient suppression.

Since the CDLL4688 is a single type diode, it is suitable for use in logic circuits, signal clamping circuits, voltage doublers and voltage regulators. It is also suitable for use in low-power switching applications, such as in low-power switches, LED amps, LED signaling, LED sequencers and LED signal flashing.

Working Principle

The CDLL4688 single type diode works on the principle of a zener breakdown. Like all zener diodes, it produces a reverse breakdown voltage and regulates the voltage applied to it. The breakdown voltage of the CDLL4688 is 5.6 V. The reverse breakdown voltage, breakdown current and maximum power dissipation of the CDLL4688 are 5.6 V / 200 mA / 4 W respectively.

The CDLL4688 diode has two terminals - an anode (positive) and a cathode (negative). When current flows through the diode, the anode is always positive with respect to the cathode. When the reverse voltage is applied, current flows from the cathode to the anode. This current is called reverse bias current and it is limited to a particular value. When the reverse voltage exceeds the breakdown voltage, the current increases sharply and this is referred to as the Zener breakdown.

The Zener breakdown allows the diode to act as a voltage regulator. When the voltage is too high, the Zener breakdown allows it to be regulated to a lower voltage. This is why it is used in power supply design and voltage regulation circuits.

Conclusion

The CDLL4688 single type diode is a versatile component that can be used in a wide range of applications. It is well suited for use as a power rectification and voltage regulation device, as well as in protection, logic and low-power switching circuits. This is because it works on the principle of Zener breakdown, which allows it to regulate voltage or to block reverse current.
