Diodes - Zener - Arrays

The AZ23C7V5-HE3-18 is a Zener-type diode array, used to protect a circuit from overvoltage conditions. It combines a number of semiconductor junction diodes stacked in series, providing a maximum reverse and transient voltage rating of 17V. The reverse peak current rating of the AZ23C7V5-HE3-18 array is 400mA, making it suitable for circuit protection devices.

Applications

The AZ23C7V5-HE3-18 is used as a protection component in consumer, industrial, and automotive applications. It is often found in gates, surge prevention circuits, power control modules, and voltage stabilizers, as well as in automotive current control and overvoltage protection. It is also used to form a low-voltage reference, change electrical signals, and eliminate ground-noise currents.

Working Principles

The basic principle of a Zenner-type diode array is the use of a solid state, semiconductor material. Such a material is capable of conducting current in one direction but not in the reverse direction, thus providing protection in the event of power overload. This makes the AZ23C7V5-HE3-18 array ideal for protecting circuit components from short circuits and transient overvoltages.

The diode-stacking technique of the AZ23C7V5-HE3-18 array is based on the principle that when the diodes in the array are connected in series and a voltage is applied, the current flows in the direction of the applied voltage gradient. This current is distributed equally among the diodes. The resultant voltage at each diode is equal to the sum of the applied voltage minus the cumulative values of the traversed diodes. This ensures that when an overload or transient voltage condition is applied to the circuit, the array ensures that no single diode carries too much current, thus providing circuit protection.

The AZ23C7V5-HE3-18 is designed to withstand up to 17V of reverse-voltage transient protection. This means that the array is capable of reducing the voltage applied to the protected circuit during overvoltage conditions. The maximum reverse peak current rating of the AZ23C7V5-HE3-18 is 400mA, which means that the array will not overload the circuit components it is protecting.

As an added bonus, the AZ23C7V5-HE3-18 also offers some level of signal signal processing capabilities. By connecting the diodes in series and connecting their anodes and cathodes to adjacent stages, it is possible to form a DC reference voltage. This reference voltage can then be used to filter noise from the signal before it goes through the protected circuit.

Conclusion

The AZ23C7V5-HE3-18 is a Zener-type diode array that provides circuit protection against transient overvoltages and short circuits. Its reverse peak current rating of 400mA ensures that the array will not overload the components it is protecting. It also offers some signal processing capabilities by permitting the formation of a DC reference voltage. Overall, the AZ23C7V5-HE3-18 is an effective solution for overvoltage issues in a range of consumer, industrial, and automotive applications.
