BZX84C3V3S-7-F application field and working principle

Introduction to “Diodes - Zener - Arrays”

A Zener diode is an example of a two terminal semiconductor device that is specifically designed to provide protection against overvoltage conditions caused by voltage transients or other power surges. The two terminals of the diode are designated an anode (the positive terminal) and a cathode (the negative terminal). Like all diodes, a Zener diode will allow current to flow in one direction -- from the anode to the cathode; however, under certain conditions -- higher forward voltages -- the Zener diode will allow the majority of the current to flow in reverse direction, from the cathode to the anode. This special ability of the Zener diode makes it possible to protect electronic circuits from overvoltage conditions.

Arrays of Zener diodes are nothing more than a variety of diode configurations consisting of multiple individual diodes in an integrated package. By combining several individual diodes with different voltages, designers can create multiple voltage levels with the same package size. The most common array packages feature diametrically opposite Zener pairs with the same nominal voltage, or bilateral denominators that offer higher breakdown voltages without the need for additional space. Arrays can also but combined with other devices and substrates such as resistors and transistors to create different voltage levels across multiple devices in the same package.

BZX84C3V3S-7-F Feature Summary

The BZX84C3V3S-7-F is an integrated array package composed of 7 individual Zener diodes with different nominal breakdown voltages. This array provides designers with the ability to create multiple voltage levels in the same package. The individual diodes have a nominal breakdown voltage of 3.3 V, 3.9 V, 5.1 V, 7.5 V, 10.0 V, 15.0 V, and 20.0 V. This array is the ideal solution for designers looking to reduce the size of their designs and maintain the same functionality.

BZX84C3V3S-7-F Working Principle

The basic principle behind Zener protection diodes is that when a certain amount of reverse voltage is applied, the diode will allow more current to flow in the reverse direction than it does in the forward direction, creating a protective buffer for the electronic device. In the case of an integrated array of Zener diodes, such as the BZX84C3V3S-7-F, when reverse voltage is applied, the more resistant diodes in the array act as a shield and allow only the specified amount of current to flow in the reverse direction, protecting the device it’s connected to.
