Working Principle

The working principle of the CDLL974A Zener diode is based on the PN junction breakdown process. This type of diode consists of two different semiconductors with different doping types connected together. The diode is so designed that when a current equal to the maximum allowed rating is applied, the reverse voltage across the diode increases and causes the breakdown of the PN junction. At this breakdown voltage, a sharp increase in the current flows. The current will then continue to increase until it eventually reaches its peak value. The Zener voltage and the breakdown current of the CDLL974A diode can be adjusted by varying the doping ratio of the two different semiconductors. This allows for greater flexibility in the design of the product.The CDLL974A Zener diode is capable of providing voltage regulation from 0.2 to 30V. It also offers very low forward current flow, making it suitable for use in low power circuits. It is also capable of providing a stable voltage regulation against changes in temperature. As a result, it can be used in high temperature environments without being affected by the adverse effects of temperature change.
