It has a maximum operating temperature of 125°C and can withstand transient over-voltages of up to 10V.

Working Principle

The basic working principle of the CDLL5914D is based on the characteristic of a traditional PN junction diode. The diode consists of two doped regions of semiconductor material, one more heavily doped than the other. When reverse-biased, the heavily doped layer is forward-biased and passes conduction in the reverse direction. This creates a localized electric field that raises the voltage of the less heavily doped layer from the normally negative-biased region to a higher negative-biased region.

The voltage between the two layers is referred to as the Zener voltage. In this condition, the diode is said to be in the breakdown mode, meaning that its resistance is very low in the forward direction. The current is regulated by the voltage of the Zener layer, which is maintained at a nearly constant value by adjusting the voltage across the diode. This creates a voltage regulator that is used to provide a constant voltage source, regardless of the current.

The CDLL5914D offers superior performance due to its low-voltage characteristics and superior reverse-leakage current. Additionally, it is designed to provide enhanced thermal stability, enabling it to operate at higher temperatures and providing longer operational life. It is also designed with an improved total distributed capacitance, ensuring that it can accurately regulate the voltage delivered to downstream components.
