Diodes - Zener - Arrays

The AZ23C30-HE3-08 is a type of semiconductor array that is made up of two or more interconnected diodes, usually in a single package. It is most commonly used with integrated circuits that require multiple n-channel zeener diodes and is used in a wide range of applications. In this article, we will discuss the application field and working principle of the AZ23C30-HE3-08.

Application Field

The AZ23C30-HE3-08 is most commonly used in field-effect transistor (FET) applications, where it acts as a source follower current sink, in order to provide constant current and voltage characteristics for the FET. This device also finds applications in distributed feedback laser diode designs, where it is used to create a controllable impedance across the diode. In addition, the device is also used in low frequency analog-to-digital converter (ADC) systems, where it acts as a voltage reference element and in buck-converter-based dc-dc converters, where it creates a voltage regulation circuit.

Working Principle

The AZ23C30-HE3-08 is a combination of n-channel Zeener diodes, all of which are connected in series and have the same polarity. The series combination creates a voltage-dependent resistance, often referred to as a “zener” or “diode array”. The device has a tuned capacitance that enables the device to respond quickly to changes in the applied voltage, allowing it to maintain a stable output voltage across a range of input voltages.

The device is usually used with circuitry that requires a constant voltage or current reference. When the applied voltage exceeds the programmed threshold, the diode array begins to conduct and the current output of the device is proportional to the applied voltage. It is this characteristic that allows the device to maintain a constant voltage or current across its output terminals, regardless of the input voltage.

The device also offers some degree of temperature compensation, which is important in applications where the device is used to provide a constant voltage or current output. Temperature changes can affect the performance of the device, however, this is minimized due to the temperature compensation offered by the diode array.

Conclusion

The AZ23C30-HE3-08 is an integrated semiconductor array that combines multiple n-channel Zeener diodes into a single package. It is used in a wide range of applications, from providing voltage regulation in distributed feedback laser diode designs to providing constant current and voltage characteristics for FETs. The device has a tuned capacitance that enables it to respond quickly to changes in the applied voltage and offers some degree of temperature compensation.
