The CDLL3828 is a single zener diode, which belongs to the family of diodes, and which offers protection against over-voltage and electrostatic discharge. The CDLL3828 is designed to protect sensitive electronic circuits from over-voltage and electrostatic discharge-induced damage, such as static electricity. It can also be used in low voltage circuits to prevent voltage excursions, thereby providing simple and effective protection for sensitive electronic components.

The CDLL3828 is characterized by its low operating current, low leakage current and temperature coefficient. The CDLL3828 exhibits a reverse blocking voltage with an impressive working range of 5.3V to 25.5V. Its maximum power dissipation is 150mW, and its breakdown voltage range is from 7V to 13V with a +/-5% tolerance. In addition, the CDLL3828 can handle up to 200mV of surge current.

The CDLL3828 is well suited for applications where its operating voltage is higher than the reverse breakdown voltage of the protected components. The device can protect against electrostatic discharge of up to 200mV by providing a path to ground for static buildup. It also shields against electrical noise and prevents over-voltage buildup or short circuit condition in circuits where voltage or signal stability is highly important. It is also suitable for use in various voltage sensitive circuits, including audio, video, and telecommunication systems.

The working principle of the CDLL3828 is based on the principle of reverse bias operation. The diode is reverse biased when it is mounted in the circuit, allowing electrons to flow freely in one direction. Once a certain reverse breakdown voltage is reached, the electrons will accelerate and will be blocked from entering the junction. This creates an avalanche breakdown that causes the diode to begin conducting, limiting the voltage and preventing damage to the protected component.

In summary, the CDLL3828 is an ideal choice for protecting sensitive electronic circuits from over-voltage and/or electrostatic discharge damage. It offers excellent performance characteristics, including low operating current, low leakage current, and temperature coefficient. The CDLL3828 is widely used in various voltage sensitive circuits, including audio, video, and telecommunication systems.
