Zener diode arrays are a quintet of zener diodes manufactured together on a single semi conductor chip. Zener diode arrays are often used in applications requiring high current or low voltage drops. With zener diode arrays, voltage regulator circuits are easily achievable without the hassle of having to use multiple zener diodes. The BZX84C15S-7-F from Diodes Incorporated is an example of a zener diode array. This article will discuss the application field and working principle of this device.

The BZX84C15S-7-F is a compact SOT-23 5-Pin package containing five Zener diodes with a 7.5V average Zener voltage. Its Zener breakdown voltage range is 6.2V to 8.2V and its maximum power dissipation is 500mW at a 30mA current. Aside from its electrical properties, it also has an operating temperature range of -55°C to +150°C, a storage temperature range of -65°C to +150°C, and a 260°C max junction temperature.

The BZX84C15S-7-F can be used for many different applications. One of the most useful applications for this Zener diode array is that it can be used to create a low-dropout (LDO) linear regulator. Using this diode array, a continuous output voltage can be provided for a wide range of DC voltage inputs. This makes this device ideal for many power-supply applications such as microcontrollers and other FPGA-based circuit designs. Additionally, the BZX84C15S-7-F can be used in rail to rail voltage regulators, CMOS power supplies, and low-noise power supplies. Its small size also makes it perfect for portable devices and embedded applications.

The BZX84C15S-7-F utilizes a simple built-in thermionic emission principle in order to provide a regulated output voltage. In this design, the regulating voltage of the array is determined by the threshold voltage of the integrated Zener diodes combined with the amount of current in the cathode circuit of the diode. The array outputs a fixed voltage when an input voltage is applied and an electric current drawn across the diode. As the Zener diodes act as a series of shunt regulators, this device requires no external control elements and is able to provide protection from over-voltage conditions.

To sum up, the BZX84C15S-7-F is a five-pin device that contains five Zener diodes in a single package. It is suitable for use in applications requiring a low-dropout linear regulator, rail-to-rail voltage regulators, CMOS power supplies, and low-noise power supplies. It uses thermionic emission as its primary regulating mechanism and is able to provide protection from over-voltage conditions. Thus, the BZX84C15S-7-F is an ideal solution for many different power supply applications.
