Introduction to AZ23C11-HE3-18

The AZ23C11-HE3-18 is a type of Zener diode array that is used to provide protection for micro-controllers, power circuits, and other sensitive electronic components. It is a three-terminal, three-diode protection diode array designed for a wide voltage range of 5.0V to 15.0V. This diode array offers high surge current capability and low clamping ratio with tight tolerances on its reverse breakdown voltage and other related specifications.

Applications of AZ23C11-HE3-18

The AZ23C11-HE3-18 is typically used as an overvoltage protection device for micro-controllers, FPGAs, DSPs and other sensitive electronic components in automotive, industrial, and consumer applications. It can be used in power circuits, especially those that demonstrate higher surges in their input signals. Additionally, it is suitable for use in applications that require a high level of accuracy in determining the voltage breakdown levels, as the AZ23C11-HE3-18 offers very tight tolerances on its reverse breakdown voltage.

Working Principle of AZ23C11-HE3-18

When a voltage exceeds the specified threshold for the protective diode array, the internal diodes will begin to clamp the voltage. This is done by the capacitance between the anode and the reverse power output path. As the voltage increases above the predetermined value, the AZ23C11-HE3-18 works to keep the output voltage across the load within the specified range.The AZ23C11-HE3-18 also has high surge current capability and low clamping ratio, which are beneficial in applications where a large current surge is expected in the input signal. Additionally, the AZ23C11-HE3-18 can provide high accuracy in determining the protected voltage range, thanks to its tight tolerances on the reverse breakdown voltage.

Conclusion

In conclusion, the AZ23C11-HE3-18 is a type of Zener diode array that offers robust overvoltage protection for micro-controllers, power circuits, and other sensitive electronic components. It is often used in applications that require high accuracy for determining the voltage breakdown levels. In addition, it has high surge current capability and low clamping ratio, providing robust protection for incoming high-current surges.
