Diodes - Zener - Arrays

The AZ23C12-HE3-08 is a series of double-channel zener arrays from Microsemi. As one of the leading zener diode arrays on the market, the AZ23C12-HE3-08 is widely used for its reliable operation and through-hole mounting for a variety of applications. This article explains the application field and working principle of the AZ23C12-HE3-08 to give readers a better understanding of this technology.

Application Field

The AZ23C12-HE3-08 is widely used for its ability to provide fast and reliable protection from a wide variety of electrical interference sources. Its two arrayed zener diodes, connected in parallel, can limit the current to a safe level, providing protection from up to 20KV. This makes the AZ23C12-HE3-08 a perfect solution for applications such as voltage protection, line protection, and motor speed reduction. Its through-hole mounting also adds to its flexibility, allowing it to be mounted in virtually any type of electrical system.

The AZ23C12-HE3-08 is also an ideal solution for applications that require a fast response time to external signals. Its low on-state voltage drop, combined with its fast switching time of approximately 1 microsecond, makes it a great choice for automated control systems, as well as applications that require pulse modulation and high-frequency switching. Its ability to handle up to 20A of current makes it a perfect choice for larger industrial applications as well.

The AZ23C12-HE3-08 is also suitable for applications that require environmental friendly solutions. It is RoHS (Restriction on Hazardous Substance) compliant and meets the criteria for various eco-label standards such as Energy Star and BLI (Boreal Light Industry). This makes it an ideal solution for applications where clean energy is desired.

Working Principle

The AZ23C12-HE3-08 works by providing a fast and reliable method of limiting current flow to a safe level. Its two arrayed zener diodes, connected in parallel, form a voltage breakover region that limits current flow. This circuit utilizes a standard zener voltage of 5.1V and is designed to provide protection up to 20KV. The two diodes act together, redirecting any current above the voltage breakover region to ground for protection.

When the current passing through the AZ23C12-HE3-08 is below the zener voltage, then it will remain in its "on" state and allow current to pass through. However, when the current surpasses the zener voltage, the AZ23C12-HE3-08 will redirect the excess current to ground, thus preventing a potentially hazardous situation. This action happens within 1 microsecond, making the AZ23C12-HE3-08 perfect for applications requiring a fast response time.

The AZ23C12-HE3-08 is calibrated to operate at temperatures up to 85°C, making it perfect for a wide variety of applications. Its through-hole mounting makes it easy to install and gives it great flexibility in terms of installation location and orientation. The AZ23C12-HE3-08 is also available in various packages, making it an ideal solution for a wide range of applications.

Conclusion

The AZ23C12-HE3-08 is a series of double-channel zener arrays from Microsemi that is widely used in a variety of applications. Its two arrayed zener diodes, connected in parallel, limit the current to a safe level, providing protection from up to 20KV.
