Diodes - Zener - Arrays

The AZ23C18-7-F is a component of the Zener diode family and is a unique, highly integrated array. Zener diodes are widely used in electronics and come in a variety of shapes and sizes, providing a range of features and benefits. Like any other diode, they act as a barrier to electric current in one direction and are used to protect sensitive circuitry. In addition, they also have the special properties of a Zener diode, which makes them distinct from other types of diodes. Zener diodes, including the AZ23C18-7-F, are specially designed to maintain a steady voltage across their terminals in the presence of an AC or DC source.

Application

The AZ23C18-7-F has two terminals and is designed to be used in pairs in a wide variety of applications. They are often used in situations where two groups of signals need to be kept separated while each group is at a different voltage level. This particular device is a Capacitor Coupled Switchable Zener Diode Array, which is useful in many electronic and electrical applications. The AZ23C18-7-F is an 18-Pin array, with each pin having an equal impedance, hence providing consistent voltage lvels.

One common use of the AZ23C18-7-F is in the area of overvoltage protection on the primaries of DC to DC converters. The device helps to protect sensitive components and boards from surges or spikes in voltage. It is also used for current limiting in power supplies, especially those connected to motors or inductive loads. The device can also be used in power supplies for TV equipment, computers, and audio amplifiers as a form of transient protection from overvoltage.

Working Principle

The primary function of a Zener diode, including the AZ23C18-7-F, is to maintain a steady voltage between its two terminals in the presence of an AC or DC source. This is achieved by a process known as Zener breakdown. Zener breakdown occurs when the electric field within the diode reaches a strength that is sufficient to break down its internal structure, allowing electrons to flow freely.

The specific operational characteristics of the AZ23C18-7-F make it particularly useful in situations where two groups of signals need to be kept separated while each group is at a different voltage level. In this situation, the Zener diode acts like an electronic switch, allowing current to flow through it in one direction, while blocking it in the other. The device behaves in this way regardless of the frequency and amplitude of the input signals.

It is also helpful to understand the construction of the AZ23C18-7-F in order to gain insight into its operation. The 18 pins of the device are arranged in two linked rows, with each row being connected to its opposite number. This arrangement enables the Zener diode to function in arrays, allowing for multiple voltages to be used without interfering with each other.

The AZ23C18-7-F Zener diode array is a highly efficient and reliable device which is able to provide protection from over voltage, enabling the avoidance of damage or destruction to sensitive equipment. Its wide range of applications, as well as its relatively low cost, make it an ideal choice for many applications.
