Diodes - Zener - Arrays

A Zener diode array, also referred to as a Zener array, is an integrated circuit that is designed to regulate voltage across an electrical circuit. In particular, it is suited for applications requiring voltage regulation in extreme conditions and with varying temperature. The AZ23C3V9-E3-08 is a type of Zener diode array, and the following will discuss the applications and the working principles of this type of diode array.

Applications

The AZ23C3V9-E3-08 Zener diode array is a widely used and reliable device able to block reverse voltage along with providing voltage regulation in extreme conditions. It is a widely used device in many industries such as automotive and medical applications. In automotive applications, for instance, the AZ23C3V9-E3-08 diode array can provide voltage stabilization in the charging and alternator systems as well as other electrical components. Furthermore, with its reliable temperature compensating properties and its capability to filter out spurious signals it can ensure temperature regulation in electronic components like spark plugs and other onboard computer systems.In medical applications, the AZ23C3V9-E3-08 diode array is regularly used in medical devices such as patient monitors and other diagnostic systems that require secure voltage regulation on power supplies.

Working Principle

The AZ23C3V9-E3-08 diode array is a 5-pin diode array connected in a series/parallel configuration that is composed of zener diodes connected in parallel and then connected in series. When the diode array is activated, the voltage appears across the parallel diodes. This high voltage then has to be regulated by a high-side zener to limit the peak voltage value that is given to the protected circuit.The AZ23C3V9-E3-08 diode array works in two diverse modes. The first mode is called the “static mode” and it has a fixed voltage reference with a tolerance of ±2%. This mode is usually selected when the load exhibits no or minimal fluctuations in its load current. The second mode is the “dynamic mode” and this mode has a continuously changing voltage reference that adjusts itself to track the changing load currents. This mode is usually chosen when the load exhibits a changing load current. The purpose of the dynamically adjusted voltage reference is to regulate the amount of current drawn by the load without any troubles.

Conclusion

In conclusion, the AZ23C3V9-E3-08 Zener diode array is a type of integrated circuit created for voltage regulation in extreme conditions and with varying temperature. It is a well renowned and dependable device that is used in various applications such as automotive and medical. It is operated using two diverse modes - “static mode” and “dynamic mode” - which have specific voltage references and tolerances. With its reliable temperature compensating properties, the AZ23C3V9-E3-08 diode array is able to provide voltage stabilization.
