Introduction

CDLL5246A is a type of single Zener diode. It is especially useful due to its low voltage and high leakage current. It has a wide range of applications, including as a voltage regulator. The working principle of a Zener diode is quite simple and it can be explained as follows: When the voltage is greater than its Zener voltage, the Zener current passes through the device, lowering the voltage and stabilizing it.

Physical Characteristics

The CDLL5246A diode is a two-level axial type diode. It features a ceramic body with gold plated pins. It is made from PN junction material and its physical dimensions are 17.4mm x 9.52mm ( L x W). The operating temperature of the device ranges from -65°C to +150°C, with a storage temperature of -65°C to +150°C.

Working Principle

The Zener diode works by allowing current to flow through it in one direction, but not in the other. This is done using an approximate ‘Zener′ voltage across the diode. This Zener voltage is the voltage across the diode when it is forward biased. When the voltage is lower than the Zener voltage, the diode acts like an open circuit and no current flows. However, when the voltage is greater than the Zener voltage, the diode allows current to flow and it passes through the device, reducing the voltage and stabilizing it.

Conclusion

The CDLL5246A is a single Zener diode that is highly reliable and suitable for a wide range of applications. It is characterized by low power dissipation and low leakage current. Its low capacitance makes it suitable for high-speed switching applications. It is easy to install and maintain, and it is widely used in power supplies, data-line protection, and circuit boards. Its Zener working principle is quite simple and it allows current to pass through the device, reducing voltage and stabilizing it.
