Diodes – Zener – Arrays are components used mainly in power electronics applications. AZ23C16-7 is the most common type of diode array used today in such applications. This article will explain the application field and working principle of AZ23C16-7.

Application Field

AZ23C16-7 is a 16-pin package diode array composed of 8 Zener diodes and 8 Schottky diodes. It is mainly used for vital applications in power electronics such as voltage regulation, ESD protection, and DC/DC power converters. The AZ23C16-7 is used for different purposes ranging from voltage spike protection of on-board circuits to power switching in motor control applications.

The AZ23C16-7 is the preferred choice for applications where smaller and higher power dissipation is demanded due to its small die size and lower leakage current. It is versatile and easy to use, and ideal for applications where current spikes must be limited, such as in solar power, switched mode power supplies, and automotive electronics.

Working Principle

The AZ23C16-7 uses a two-layer integrated circuit which offers a combination of two different types of diodes, the Zener and the Schottky. The Zener diodes protect the application from voltage spikes that could damage the components, while the Schottky diodes provide high switching speed and low forward voltage drop. The Zener diodes act as voltage regulators, regulating the input voltage to the desired output voltage. The Schottky diodes additionally act as flywheel diodes to ensure stable current flow.

The AZ23C16-7′s on-state resistance (Ron) is low, and its forward voltage drop is minimized, making it suitable for high frequency and low voltage applications. The device also has a high current rating, allowing it to handle current spikes of up to 2,000mA.

The AZ23C16-7 can operate from a wide range of temperatures, from -40°C to +85°C, and the package is lead-free and RoHS compliant. It can be mounted to a variety of substrates using conductive thermal epoxy on the PCB.

The AZ23C16-7 is a versatile diode array suitable for many power electronic applications such as regulators, power switching, motor control, and ESD protection. Its high power dissipation, low on-state resistance, and low cost make it an ideal choice for various applications and power levels.
