The CDLL3049B-1 is a single Zener diode component component designed and manufactured by NXP, specifically designed to help protect circuits against voltage surges. It features a four-layer structure, with a Zener diode, a breakdown meter, a bridge rectifier and a two-channel series voltage regulator. The component works by limiting the voltage at the protected component to its breakdown voltage, which is rated at 0.99V.

The CDLL3049B-1 is designed to be used in circuits with a wide range of voltage levels, ranging from 7V to 25V. The component protects the circuit against voltage surges, short circuits and reverse polarity. It is also designed to work in high temperatures, operating at a temperature range of -55°C to 125°C. It has low forward voltage drop and reverse leakage current, and is capable of operating at up to a 5.0V reverse breakdown voltage.

The CDLL3049B-1 is mainly used in applications such as power supplies, automotive audio systems, automotive electronics, electro-optical equipment, industrial automation systems and medical equipment. In these applications, the component helps protect the circuits from voltage spikes, ensure the accuracy of the signals and provide reliable and efficient system performance. It is also used in solar panel systems, where it helps protect the solar panel from damage due to high voltage.

The working principle of the CDLL3049B-1 is based on Zener breakdown. When a voltage is applied across its terminals, the voltage across the diode increases. When the applied voltage reaches the breakdown voltage of the device, the diode starts to conduct. This causes the voltage across the terminals to drop, allowing the device to protect the circuit from further voltage spikes. The device also features a bridge rectifier, which ensures that the current flows in only one direction. This helps protect the device against reverse voltage and helps reduce the power loss caused by the diode.

The CDLL3049B-1 is a single Zener diode component that is designed to protect circuits from voltage surges and ensure the accuracy of signals. Its low forward voltage drop and reverse leakage current helps to increase system efficiency and reliability. Its wide operating temperature range and high reverse breakdown makes it suitable for use in a variety of applications. It is an ideal solution for protecting circuits in power supplies, automotive electronics, electro-optical equipment and more.
