A Zener diode array, such as the AZ23B11-G3-18, is used as a voltage regulator in a wide range of applications. A Zener diode array consists of a number of Zener diodes connected together in series or parallel depending on the application and design. Each diode has a different breakdown voltage, which allows the diode array to regulate the output voltage accurately throughout its range.

The AZ23B11-G3-18 is a Zener diode array manufactured by STMicroelectronics. This Zener diode array is constructed from four Zener diodes that are connected in parallel. Each diode has an 18-volt breakdown voltage, providing a total of 72 volts. The AZ23B11-G3-18 also includes a diode protection circuit that is used to protect the array from short-circuits, over-voltage and over-temperature.

Zener diode arrays are most often used in voltage regulator circuits. In these applications, the array is placed in series with the input voltage. The Zener diodes in the array act as a variable resistance, allowing the output voltage to be regulated at a pre-determined level. This makes them ideal for applications where a stable output voltage is required, such as in power supplies, medical equipment and automotive electronics.

Zener diode arrays can also be used as voltage dividers. In this application, the array is placed in series with two resistors. The Zener diodes in the array act as a variable voltage divider, allowing the output voltage to be adjusted over a certain range. This makes them ideal for applications where the output voltage needs to be adjustable, such as in audio equipment and communication systems.

The AZ23B11-G3-18 is a reliable and robust Zener diode array. It is capable of operating in temperatures ranging from -65°C to +125°C, and it has a maximum reverse current of 1.0 mA. This Zener diode array is available in four different voltage configurations, providing a wide range of options for applications requiring low-current regulation.
