CDLL4748 is a single Zener diode device, developed by the American company Texas Instruments Inc. It is used to regulate and protect circuits from overvoltage and as a current source in high power applications. The device has a reverse-protected design, and is capable of withstanding up to 10A in continuous operation.

The CDLL4748 is a two-terminal component with a 0.3mm package, so it can be easily integrated into a circuit board or chassis. The device features an integrated Zener diode for clamping and an inductive load for impedance compensation. It also features an internal protection circuit, which limits the input/output current to protect the device and clear any short-circuit conditions.

The CDLL4748 provides excellent linearity up to 100V, which ensures precise output voltage control and efficient overload protection. It also features thermal shutdown and reverse breakdown protection, giving it a high level of reliability. The component has a low operating and standby power consumption, making it ideal for applications where power management is essential.

The CDLL4748 is widely used in industrial and high power applications, and has proven to be a stable, reliable and cost effective solution. It is used in power supplies, solar and renewable energy systems, and medical equipment for voltage regulation and current limiting. The device is also suitable for automotive applications, such as electronic engine control systems and 12V power supplies.

The working principle of the CDLL4748 is simple. When a voltage exceeds the zener breakdown voltage, the zener diode conducts and the device’s internal protection circuit limits the voltage across the output. This ensures the output voltage is regulated to the desired level and that no damage is caused to downstream components. When the input voltage is lower than the breakdown voltage, the device’s inductive load compensates the impedance and limits the current flow.

The CDLL4748 is a versatile, reliable and cost effective solution for high voltage, high power applications. Its integrated protection and overload protection circuits ensure its performance and reliability, while its low power consumption makes it an ideal choice for power management applications.
