Zener diode arrays are semiconductor components which incorporate two or more Zener diodes in one single package. The DZ23C15-7-F is one example of a Zener diode array, which is typically used in AC/DC converters and levels/voltage/power supply controllers. This device offers an easy and efficient way to incorporate multiple diodes into a product without needing to individually add multiple components.

A Zener diode array typically consists of two or more Zener diodes, a diode rectifier, and a set of controllable resistors. Each Zener diode has a breakdown voltage and a high reverse-voltage leakage current. When a voltage greater than the breakdown voltage is applied to the diode, the current will start to flow in the reverse direction. This process is called breakdown or reverse breakdown. The controllable resistor plays a key role in ensuring that the voltage applied to each diode is within the safe working range. The speed of breakdown is controlled by varying the resistance across the diode.

The DZ23C15-7-F Zener diode array uses a Zener voltage of 15V, which is ideal for use in medium power AC/DC switch-mode power supplies, rectifier- and voltage-regulated supply circuits, and overflow-current prevention circuits. Its features include operating ratings up to 15V, IZ(max)= 1.2A@10V, tmVr= 5μs, and maximum power dissipation of 1.7W.

When the DZ23C15-7-F is used in a typical application, such as a Buck/Boost converter, the rectifier/voltage regulator circuit as shown in the figure below provides efficient and dependable power supply control. The circuit consists of a multi-channel MOSFET switch array which senses the input voltage and, when necessary, switches between the Buck and Boost modes, keeping the output power supply at a manageable level.

The DZ23C15-7-F Zener diode array provides the necessary current level for efficient and reliable operation of the MOSFET switch. During the Buck operation mode, the Zener diode array is forward biased and allows the current to flow from the Drain of the MOSFET, through the forward-biased diode, to the Source of the MOSFET. During the Boost operation mode, the Zener diode array is reverse biased, and the current flow is reversed; in this case, the current flows from the Source, through the reverse-biased diode, and to the Drain of the MOSFET.

Overall, the DZ23C15-7-F Zener diode array offers reliable and efficient current control for AC/DC converters and power supply controllers. By controlling the current level and the breakdown speed, the DZ23C15-7-F provides efficient and dependable power supply control for DC/AC converters, power supply controllers, and other applications.
