CDLL5249B

CDLL5249B is a Zener diode with a single break-down voltage of 5.2V, capable of handling up to 500mW power dissipation at 75°C. It is commonly used in voltage regulation, clipping and clamping, signal wave shaping and stabilizing circuits, as well as converters and switching regulators. It has a wide range of operating temperature from -40 to +125 degrees. It is also used as a voltage reference in digital systems.

The CDLL5249B diode is a two terminal electrostatic device, meaning it conducts current in only one direction. It consists of a semiconductor junction formed between two materials of different dopant types, typically N and P type silicon. This creates two distinctive regions, the cathode and the anode. The electrons flow from the anode to the cathode when a forward current is applied. The Zener breakdown voltage is the voltage at which the diode begins to break down and conducts a current in the reverse direction.

The schematic symbol of a Zener diode shows its reverse flow of current. An arrow points to the cathode and a line running parallel to the arrow shows the breakdown or avalanche region. The analog symbol of the diode shows it diode as a line and a bar across it which indicates the breakdown voltage. This symbol may also be used to identify the junction between anode (positive side) and cathode (negative side).

In the CDLL5249B diode, the 5.2V breakdown voltage is the nominal reverse voltage at which a static conduction will occur. The static leakage current is the maximum of 10 microAmps at a reverse voltage of 5.2V. As the reverse voltage is decreased, the current will decrease until the diode will block any current from flowing in the reverse direction at zero volts.

The operating temperature range of the CDLL5249B from -40 to +125 degrees Celsius is kept safe thanks to its heat sink, which dissipates the heat. The heat sink helps to maintain the diode temperatures and is designed to maximize the power rating dissipation.

The cardinal features of the CDLL5249B are its high power dissipation rating at 75°C, low static leakage current, wide operating temperature range, and Zener voltage of 5.2V, making it suitable for use in many applications such as voltage regulation, clipping and clamping, signal wave shaping and stabilizing circuits, as well as converters and switching regulators.

The CDLL5249B is a standard Zener diode widely used in many commercial, industrial and automotive applications. It is easy to use thanks to its widely available standard packages. Its low price and reliable performance make it an ideal choice for many applications.
