Diodes - Zener - Arrays
AZ23B20-HE3-18 is a type of diode array specifically designed to prevent reverse current flow and maintain a stable voltage across its terminals. It consists of two arrays of diodes in an isolated package, with the anode of one array connected to the cathode of the other. This type of diode array is commonly used to protect sensitive electrical equipment from voltage surges, as it works to maintain a constant voltage level and prevent the flow of excessive current.
Application Fields
AZ23B20-HE3-18 is commonly used to protect consumer electronics devices such as smartphones, tablets, laptops, and televisions. It can also be used in other electronic components such as power supplies and LED lights. Additionally, this type of diode array is used in automotive applications, where it serves to protect electrical systems from overcurrent and reverse current.
Working Principle
When current passes through the AZ23B20-HE3-18 diode array, the forward-biased diode conducts the current while the reverse-biased diode blocks it. This prevents the flow of reverse current, which can cause damage to the electrical circuit. The reverse-biased diodes also act as a voltage regulator, which keeps the voltage across the terminals constant and prevents over-voltage situations.
The AZ23B20-HE3-18 diode array can also be used to balance AC current, and it works on the principle of rectification. As AC current passes through the array, the two diodes alternately conduct, allowing for positive and negative half cycles of current to pass through. This creates a stable, rectified DC voltage across the array’s terminals.
Advantages
The AZ23B20-HE3-18 diode array is a versatile and reliable component, offering numerous advantages over other protection components. It is a cost-effective solution that is easy to install, highly reliable, and designed for a long service life. Additionally, it is capable of handling fast current surges and voltage spikes, making it suitable for a wide range of applications.
Disadvantages
One of the main disadvantages of the AZ23B20-HE3-18 diode array is its relatively high forward voltage drop. This means that a relatively large amount of voltage is lost when current is flowing through the array. This can be an issue in applications where power efficiency is important. Additionally, the AZ23B20-HE3-18 is not designed for high-temperature applications, as the package can become unstable at elevated temperatures.
