Introduction
A diode is an electrical device with two active electrodes, the anode and cathode, separated by a semi-conductive material (called a diode bridge) that allows current to flow in only one direction. A Zener diode is a semiconductor device invented by C.V. Zener and patented in 1925. It is also known as a Zener Barrier, Zener Clamp or Zener Fuse. The Zener diode is used in electronic circuits where the breakdown voltage is adjustable and the power dissipation is generally low. AZ23B12-HE3-18 is a type of Zener diode. This paper will discuss the application field and working principle of this diode.Application of AZ23B12-HE3-18
The AZ23B12-HE3-18 is an ultra-low power consumption Zener diode that is commonly used as a voltage reference in electronic circuits. It is ideal for applications involving voltage regulation, battery protection, reverse voltage protection, and current limiting. It has a low forward voltage drop and its reverse leakage current is low, making it suitable for sensor circuits and analog circuits where power consumption should be minimized. It is also used in microcontroller circuitry and AC-to-DC power supplies.Working Principle of AZ23B12-HE3-18
A Zener diode is a type of diode that can be used in either a forward or reverse direction. When the diode is in the forward direction, the diode works as a normal diode, allowing current to flow in one direction. When the diode is in the reverse direction, the diode creates a large voltage drop. In this direction, the diode behaves as a voltage regulator and stabilizer, allowing a constant voltage to be maintained despite current and load variations. The AZ23B12-HE3-18 works in the same manner, but with the added ability to handle low power. It also offers a low reverse leakage current, making it ideal for battery-operated circuit applications and discrete components. When voltage is applied in the reverse direction, the diode will conduct current and the voltage will drop to a minimum breakdown voltage determined by the diode. This voltage drop will remain constant in spite of variations in the current.Conclusion
AZ23B12-HE3-18 is an Ultra-low power consumption Zener diode that is widely used in a wide range of applications including voltage regulation, battery protection, reverse voltage protection, and current limiting. It works by allowing current to flow at one direction and acts as a voltage regulator and stabilizer when a series of reversed voltage is applied. It provides and controls a constant voltage drop in spite of current and load variations.The specific data is subject to PDF, and the above content is for reference
