Diodes - Zener - Arrays

The AZ23B27-E3-08 is a diode array manufactured by 4 Star Electronics and designed specifically to act as a voltage reference and protection device. It is designed to perform three key functions: it provides protection against reverse voltage, it regulates voltage to ensure consistent and reliable power, and it offers an extra layer of protection for electrical and electronic components. The AZ23B27-E3-08 offers a wide operating temperature range of -40 to +125 degrees Celsius, allowing it to function in most ambient environments. Additionally, it includes four diodes in a SIP (Single In-line Package) which offers an easy to use form factor.

Application Field

The AZ23B27-E3-08 is well suited for use in automotive, industrial, and consumer electronics applications. It can be used in a variety of applications, including protection circuits, voltage regulation, and temperature compensation in automotive applications and power supplies, as well as in network, audio, and video equipment. Additionally, it can be used in telecommunications and military/aerospace applications.

Working Principle

The AZ23B27-E3-08 works on the principle of a reverse biased diode array. When an electric current is applied in the opposite direction than intended, the Zener diode effectively becomes a resistor. This allows the current regulation, ensuring that the voltage does not exceed the predetermined limits of the system. The reverse voltage protection aspect of the AZ23B27-E3-08 functions by providing resistance when the voltage is exceeded, preventing current surge and failure of the system. Additionally, the array of four diodes provides the necessary protection against thermal runaway, offering an extra layer of protection against overload and short-circuits.

Conclusion

The AZ23B27-E3-08 offers a reliable and cost-effective solution for voltage regulation, protection, and temperature compensation. Its four-diode Zener array protects against current surges, reverse voltages, and thermal runaway, offering reliability and durability for a variety of applications. The AZ23B27-E3-08 is an excellent choice for both high-end and low-cost automotive, industrial and consumer electronics applications, allowing for reliable power in a wide range of environments.
