BZX84B18-G3-08

The BZX84B18-G3-08 is a single Zener diode. This diode is made of a material that has a special capability to have a strong breakdown voltage when it has a higher reverse bias. This allows it to be used in a wide range of applications.

Functions of the BZX84B18-G3-08

The BZX84B18-G3-08 Zener Diode has several key features when compared to other standard diode designs. The diode is intended for voltage reference, automatic power reset and many other applications where a stable forward/reverse current is required.

A Zener Diode typically consists of a zinc oxide semiconductor plate designed to be stable above a threshold voltage. When forward-biased, the diode will limit the current and allow the voltage across it to be constant. When reverse-biased, the diode can withstand a higher voltage than a standard diode and cause the voltage across it to increase or remain stable.

The BZX84B18-G3-08 has a voltage breakdown range of 18.4V to 19.6V and the typical breakdown voltage is 18V, which provides it with extra protection and makes it suitable for a range of applications.

Applications of the BZX84B18-G3-08

The BZX84B18-G3-08 is a versatile diode that is used in a number of applications. It is often found in power supply circuits, where it can be used to protect against voltage transients or provide overvoltage protection. It can also be used in high-reliability circuits, such as in medical electronics or broadcast systems.

The diode is frequently used in the protection of electronic circuits, where it can provide protection against power surges or overvoltage, as well as protecting components from overcurrent. In low voltage circuits, it can provide voltage regulation, offer reverse polarity protection or provide an accurate reference voltage.

It is also often used as an overvoltage protection device, as it can provide precise regulation of voltage, thus preventing circuitry from being damaged. This can be used in applications such as LED lighting, LCD displays or microprocessors.

Working Principle of the BZX84B18-G3-08

The BZX84B18-G3-08 works by using the fact that the Zener voltage is much lower than the breakdown voltage. In other words, the diode starts to conduct current at a much lower voltage than other general purpose diodes. This allows the diode to begin to conduct current at a lower voltage – hence providing efficient protection from overvoltage.

When the voltage across the diode reaches the breakdown voltage, the current across the diode will become constant and the voltage will remain constant. This ensures that the device can precisely regulate the voltage and protect the circuitry from overvoltage.

Conclusion

The BZX84B18-G3-08 Zener Diode is a versatile component capable of providing protection against overvoltage and voltage transients, as well as providing an accurate voltage reference. Its ability to withstand a higher reverse bias allows it to be used in a range of applications. By understanding its working principle, one can make full use of this component- thus making it an invaluable component.
