The AZ23C24-7 array can be used to protect downstream semiconductor devices against transient overvoltage events, and demonstrates exceptional ESD protection.

Typical applications

The AZ23C24-7 diode array is suitable for a wide variety of applications including automotive electronics, telecommunications, motor control, and other industrial applications. It is especially useful when the system must contain high reliability, high speed switching, and must protect against overvoltage and ESD events.

Working principle

The AZ23C24-7 diode array provides protection against transient overvoltage events by utilizing two layers of reverse Zener diodes connected in parallel. The two layers of Zener diodes provide a very low impedance path for transient overvoltage events, including ESD. When an overvoltage event occurs, the AZ23C24-7 array will diverts the current to ground, preventing downstream semiconductor devices from being damaged or destroyed. The AZ23C24-7 array also utilizes an inherent capacitance between the two layers of reverse Zener diodes, which helps to reduce transients by suppressing the high frequency components of an overvoltage event. This capacitance helps to dampen and smooth out any overvoltage events, preventing them from reaching downstream semiconductor devices.

Conclusion

The AZ23C24-7 diode array is a cutting edge device designed for high reliability, high speed switching applications. It is capable of operating robustly in wide temperature ranges and is able to provide exceptional protection from overvoltage events, including ESD events. It is suitable for a wide range of automotive electronics, telecommunications, motor control, and other industrial applications. The AZ23C24-7 array utilizes two layers of reverse Zener diodes connected in parallel, along with an inherent capacitance between them, to provide effective protection from transients.
