Introduction to the BZX79C20

The BZX79C20 is a 500mW Zener diode belonging to the Single Zener family of components. It is a single, low-cost and reliable device that has become popular in various application fields because of its high performance and low power consumption. This article provides an overview of the device, discussing its application fields and working principles.

Application Fields of the BZX79C20

The BZX79C20 is capable of handling up to 500 mW of power and withstands reverse voltages up to 28V. It is usually used to provide voltage stabilization in power supplies, battery-powered systems, resistors and other electric circuits. Other typical application fields where this device can be used include memory protection, video signal switching, line isolation, operational amplifier biasing, noise suppression and transient-voltage protection.

Working Principle of the BZX79C20

The basic working principle of the BZX79C20 lies in the fact that when a reverse-biased voltage is applied to it, a breakdown voltage is induced and the diode starts conducting current. This device performs the job of Zener diode, which is to maintain a constant voltage throughout the circuit. As the forward current increases, the voltage of the device increases until it reaches the breakdown voltage, whereupon it returns to the predetermined voltage level. When the device is used to provide voltage stabilization, it is important to consider the maximum power rating and the peak reverse current of the BZX79C20.

Conclusion

The BZX79C20 has a wide range of applications in various electronic devices and systems due to its high performance and low power consumption. It is an ideal solution for voltage stabilization because of its ability to handle a large amount of power and withstand reverse voltages up to 28V. Additionally, its working principle is straightforward, requiring only the application of a reverse-biased voltage to induce breakdown and start conducting current.
