DDZ24C-7 Datasheet/PDFA Zener diode is a type of diode that allows current to flow in either direction but blocks it when the potential difference between the terminals exceeds a certain voltage known as the Zener voltage. When connected in the reverse bias configuration, it will conduct in the forward direction if the voltage drop across it exceeds the reverse bias breakdown voltage or Zener voltage. It is usually constructed from semiconductor material, primarily silicon or germanium.
The DDZ24C-7 is a Zener diode designed to operate in the reverse breakdown region of conduction. It is used in many electronic applications such as voltage regulation, voltage stabilization and protection from excessive voltage in various circuits. DDZ24C-7 is spec\'d for maximum peaks at 4V, 7V, 10V, 12V, 15V, 18V, and 24V.

- Industrial Electronics
Working Principle
The DDZ24C-7 is designed to operate in both the forward bias and reverse bias conduction regions. In the forward bias region, the diode acts like a regular diode and follows the typical diode current-voltage (I-V) relationship curve. When the reverse bias voltage across the terminals exceeds the Zener breakdown voltage, the diode switches to the reverse bias conduction region, allowing the current to flow in the reverse direction with a nearly constant voltage drop across the terminals.
The Zener breakdown voltage is determined by the characteristics of the P-N junction of the diode and the doping process used during the diode\'s manufacture. This voltage is typically specified by the manufacturer when the diode is purchased. The breakdown voltage is usually independent of the current flowing through the diode, however, if the current exceeds the maximum specified current or if the device temperature rises above the maximum rating, the reverse breakdown voltage will decrease.
In the application of voltage regulation, the larger the current drawn to support the load, the more the Zener breakdown voltage of the diode decreases. Therefore, it is essential to select the diode with a proper Zener voltage range, which should be higher than the operating voltage of the circuit. In addition, the maximum reverse leakage current must be considered to ensure that the diode has enough stability and reliability.
In essence, the DDZ24C-7 is a very useful component for many applications with its wide range of Zener protection voltages. Its ability to operate in both the forward and reverse bias regions makes it a great choice for most circuits that require voltage protection.
