Introduction

The AZ23B47-HE3-18 is a diode array specifically designed for high-enhancement, low power, and low noise applications. This device combines design innovations and the latest advances in semiconductor technology to provide superior performance and cost savings. The AZ23B47-HE3-18 has a sleek, modern design, and is exceptionally reliable and efficient.

Working Principle

The AZ23B47-HE3-18 is a zener diode array that features high-integration, low leakage current, and low noise performance for various applications. It utilizes a new high-efficiency limited enhancement technique to ensure low power-consumption, high performance, and low noise operation. The diode arrays are designed for applications such as voltage regulation and circuit protection, as well as DC-DC converters, automotive electronics, and power supplies. The device features three cascaded zener diodes connected in parallel. Each zener diode has their own zener voltage and breakdown voltage, allowing the device to provide up to 18V of regulated voltage. The device also has a low on resistance, allowing it to maintain high efficiency and low power consumption, while still providing reliable protection against voltage spikes and surges. When the input voltage exceeds the breakdown voltage of all the diodes, the device will reduce the output voltage in a linear manner. This keeps the output voltage within a predetermined range, protecting the circuit and devices connected to it. Additionally, when the input voltage falls below the breakdown voltage of all the diodes, the device prevents any current flow and restricts the output voltage. This ensures that the circuit and device operating voltage will always stay within the predetermined voltage range.

Application Field

The AZ23B47-HE3-18 is widely used for a variety of automotive, industrial, and consumer applications. It is designed to provide reliable voltage protection and circuit protection from high level surges and spikes, while maintaining high efficiency and low power consumption. It is also used in applications such as DC-DC converters, automotive electronics, power supplies, voltage regulation, and other power management functions. The device is also used in a wide range of consumer applications, such as laptop computers, digital cameras, and other portable electronic devices. Additionally, its high efficiency and low power consumption make it an ideal choice for applications such as solar cells and battery chargers. The low leakage current and low on resistance also make it a preferred choice for high frequency applications such as RF transceivers and other digital communication equipment.

Conclusion

The AZ23B47-HE3-18 is an advanced diode array designed specifically to meet the demands of high-performance, cost-effective applications. Its low leakage current and high efficiency offer superior protection against voltage spikes and surges, while its low power consumption keeps its costs low. This device is ideal for a wide range of applications, from automotive electronics and power supplies, to laptop computers, digital cameras, and other portable electronics. Its superior performance and cost savings make it an attractive choice for many applications.
