The BZX84B56-HE3-18 (hereafter referred to as BZX) is a single zener diode in a SOD523-E3 package from ON Semiconductor. It is a low-power surface-mount device with a wide variety of applications. Its primary function is as a voltage regulator, providing a stable voltage output from an input which can vary from a minimum to a maximum. It also has ESD protection and robust breakdown characteristics.

The BZX has a wide application field and is also very versatile. It can be used in a variety of circuits, such as switching and RF circuits, to create a stable output voltage. It is also useful in LED display circuits, LED street lights, LED flash lights, and LED-based instrumentation and automotive applications. Additionally, the BZX can be used in a variety of power supply and battery-charging applications due to its robust breakdown characteristics and ESD protection.

In terms of working principle, the BZX is a diode, which consists of two terminals that conduct current in one direction only. It allows current to flow in one direction, while blocking it in the opposite direction, resulting in a negative voltage drop. This negative voltage drop causes an output voltage that is lower than the input, which is referred to as the “Zener” effect. The BZX works by using a very high resistance when not forward biased, and a very low resistance when forward biased, which prevents excessive current from flowing and supplies a stable voltage output. This makes the BZX an ideal diode for use as a voltage regulator.

The BZX is an ideal device for low-power surface-mount applications, as it offers robust breakdown characteristics and a wide range of applications. It can be used as a voltage regulator or in other circuit configurations, providing a stable output voltage from an input with a wide range of variations. In addition, the BZX has a variety of other applications, such as LED display circuits, LED street lights, LED flashlights, and LED-based instrumentation and automotive applications. With its ESD protection and robust breakdown characteristics, the BZX is an ideal choice for power supply and battery-charging applications.
