Introduction

SMZJ3806AHE3/5B is a high performance Zener diode designed specially for applications requiring precise control of low voltages. Thus, Zener diode can now be used for series switching, regulation, and precise analog control as well.

Application Field of SMZJ3806AHE3/5B

The SMZJ3806AHE3/5B Zener diode is primarily used for series switching and regulation applications. In these applications, it can be used to keep a voltage regulator from going above or below a certain voltage. It is also used for precise analog control in which accurate voltages are required for accuracy.

Working Principle of SMZJ3806AHE3/5B

The working principle of the SMZJ3806AHE3/5B can be simply explained. In order to understand how the Zener diode works we must first look at how an ordinary diode works. An ordinary diode has a semi-conductor junction which when connected in parallel allows current to flow in one direction, that of the anode. When the anode is connected to the anode of a second diode, current will flow through both diodes in the same direction.

Now, when a Zener diode is connected in series with the other diode, the voltage on the cathode of the diode will increase if the current in the other diode is too high. This is due to what is called a Zener breakdown of the semi-conductor junction. This means that the current in the other diode will be limited by the Zener diode. As a result, the voltage at the cathode of the Zener diode will remain constant, no matter how large the current in the other diode is.

Thus, by using a Zener diode it is possible to control the voltage on a circuit to a very precise level. This is extremely important for applications such as regulating a voltage for a PC power supply, controlling the voltage on a circuit board, or controlling the voltage on an LCD monitor.

Conclusion

The SMZJ3806AHE3/5B Zener diode is a high-performance device designed for series switching and regulation applications, as well as for precise analog control. The working principle is based on the Zener breakdown, which allows for the precise control of voltage on a given circuit. The SMZJ3806AHE3/5B is widely used in applications where high voltage control accuracy is required, such as the regulation of a PC power supply or the voltage on an LCD monitor.
