CDLL966

Introduction

CDLL966 is a type of zener diode. It is a single-zone diode, meaning that its characteristics show different levels of conduction based on the applied electric potential of the junction. It is optimized to provide excellent thermal stability in varying ambient temperatures and is suitable for a wide range of applications, such as general voltage regulation, voltage coupling and signal rectification, among many others.

Features

The CDLL966 features a maximum total power dissipation of 0.25W, a breakdown voltage range of 3.2V to 28V, and a maximum reverse leakage current of 5ηA. It is available in three main packages, SS-12, AB-9, and AS-13, and is designed to work over an operating temperature range of -65°C to +175°C.

Structure

The structure of the CDLL966 consists of a base layer, an active layer (which contains the zener contact), and a second silicon layer. The active layer is the most important and contains an electrical field that is designed to protect the device from overvoltage. This layer is sandwiched between two outer layers of silicon that act as insulators for the contact and as barriers for leakage.

Applications

CDLL966 diodes are used in a variety of applications such as voltage regulation, voltage clamping, signal rectification, and overvoltage protection. They are commonly used in power supply regulators, communications equipment and computer systems. They are also used to couple two AC signals together.

Working Principle

The CDLL966 works by creating an electrical field between the base and the active layers. This electrical field is designed to protect the device from overvoltage and voltage transients. When the voltage exceeds the breakdown voltage of the diode, a reverse current flows, which prevents further increase in voltage and protects the diode from overvoltage damage.

Conclusion

The CDLL966 is a type of zener diode that is used in a wide range of applications, such as voltage regulation, voltage coupling, and signal rectification. It features a superior breakdown voltage range and excellent thermal stability in varying ambient temperatures. Its working principle involves creating an electric field to protect the device from overvoltage and voltage transients.
