The AZ23B39-HE3-18 diode array is ideal for applications that require a high current carrying capacity, such as high-power DC-DC converters. It is suitable for low power loads up to 18V and provides protection for a wide range of voltages up to 30V. The diode array can also be used in other applications such as automotive electronics, home appliances, and consumer electronics. Additionally, the device is insensitive to temperature variations and can be used in a variety of operating environments.

Device Working Principle

The AZ23B39-HE3-18 diode array works by connecting two Schottky diodes in parallel through a current limiting resistor. The two diodes are connected in anti-parallel so that when the input voltage exceeds the breakdown voltage of the diode (Vz), the high current path is supplied by the Schottky diode, thereby limiting the current through the circuit. When the input voltage drops below the breakdown voltage, the current flows through the Schottky diode and the current limiting resistor. This reduces the voltage across the device and prevents overvoltage conditions. In addition, the device also provides reverse voltage protection by limiting the current in reverse directions.

The AZ23B39-HE3-18 is designed for use in DC-DC converter applications, as it offers superior performance compared to traditional protection diodes. The device reduces the voltage across the circuit, ensuring that the input voltage is within specification, and it is also less sensitive to temperature variations than other types of protection diodes. This makes it ideal for a variety of applications.
