AZ23C47-HE3-18 Application Field and Working Principle

Zener diodes are a special class of diodes that has properties suited for applications such as voltage regulation, signal conditioning, power conditioning, and overvoltage protection. The AZ23C47-HE3-18 is one of the products from Central Semiconductor Corporation’s broad selection of Zener diodes, part of the Zener Array Series. This particular product is an array of five Zener diodes in a single package, which offers a variety of benefits such as high reliability and easy interconnectivity.

General Description of AZ23C47-HE3-18

The AZ23C47-HE3-18 Zener diode array consists of five 10V Zener diodes connected in parallel, with each diode capable of supporting up to 0.5W of power rating. Its breakdown voltage ranges between 9V and 11V and its forward voltage is typically around 0.6V max. It also has a surge current rating of 40A peak at a 50us pulse, which allows it to absorb transient overvoltages. The AZ23C47-HE3-18 is packaged in a mini-SMA (Dual-In-Line) package that allows for easy interconnectivity between boards. It is also shielded from high temperature and other environment disturbances, making it highly reliable for industrial and automotive applications.

Application Field of AZ23C47-HE3-18

Due to its small size and high reliability, the AZ23C47-HE3-18 is well suited for a wide variety of applications. One example of its utility is in automotive applications, where it can be used to absorb transient overvoltage such as transients and ESD from the ignition system. It can also be used in power conditioning applications such as in switching power supplies and AC-DC converters. In addition, it is often used in industrial applications for voltage regulation and signal conditioning for microprocessors and other digital logic circuits.

Working Principle of AZ23C47-HE3-18

The working principle of the AZ23C47-HE3-18 is the same as any other diode devices. It allows current to flow in one direction while blocking current in the opposite direction. When the diode is reverse biased, such as when the voltage on the anode is higher than the voltage on the cathode, the diode is said to be in the ‘OFF’ state and no current is allowed to flow. When a forward voltage is applied, such as when the voltage on the anode is lower than the voltage on the cathode, the diode is said to be in the ‘ON’ state and current can flow through it. Since the AZ23C47-HE3-18 is a Zener diode, it also exhibits a further property, known as the Zener effect. This effect allows for a regulated voltage when a reverse voltage is applied. This is achieved by causing the reverse current to exponentially increase when the applied voltage reaches the breakdown voltage, thus allowing for regulated power.

Conclusion

The AZ23C47-HE3-18 from Central Semiconductor is a reliable diode array that is well suited for a wide range of applications, ranging from automotive to industrial applications. Its miniature size and high surge current rating make it a great choice for high reliability and ease of interconnectivity. Its working principle is the same as any other diode, except it also exhibits the Zener effect, allowing it to provide regulated power when a reverse voltage is applied. With its high reliability, small size, and ability to provide power conditioning, the AZ23C47-HE3-18 Zener diode array is an ideal solution for a variety of applications.
