Diodes - Zener - Single

As one of the most common and important types of diode, the Zener diode can be used in numerous applications. The 2EZ19D5, in particular, is a single diode specifically designed for voltage regulation, signal processing, and switching or signal rectification. Here, we discuss the application field and working principle of the 2EZ19D5 Zener diode and how it can be utilized in different scenarios.

Application Field

The SOD-123 package 2EZ19D5 diode can be used to regulate voltages in various applications. For example, it can help to stabilize power output in power supplies and protect other sensitive components from overvoltage. In addition, it can be used for voltage regulation and as a voltage divider in amplifying circuits. This diode can also be used as a medium to suppress electromagnetic interference. Furthermore, the 2EZ19D5 diode is used in various signal rectification, switching, and signal processing applications.

Working Principle

The 2EZ19D5 Zener diode has a reverse breakdown voltage of 5.1 V and a maximum power dissipation of 600 mW. As a reversed biased diode, when the voltage across the diode exceeds the breakdown voltage, the Zener diode will conduct current in the reverse direction. This means that even after the initial breakdown voltage is exceeded, the voltage difference between the anode and cathode is still high enough to sustain current flow. As such, it is possible to use this diode to regulate voltage by having a reverse breakdown voltage that is lower than the input voltage.

The Zener diode also has a low dynamic impedance which is responsible for its ability to maintain a relatively constant voltage once a certain breakdown voltage has been exceeded. The dynamic impedance is the ratio of the rate of change of current with respect to the rate of change of voltage, and it determines the rate at which voltage across a diode can change. The low dynamic impedance of the 2EZ19D5 Zener diode allows for the regulation of constant and stable output voltages.

Conclusion

The 2EZ19D5 Zener diode can be used in various applications including voltage regulation, signal rectification, and signal processing, and switching applications. The diode operates by having a reverse breakdown voltage that is lower than the input voltage and with a low dynamic impedance to ensure a constant voltage output. With its versatile function and attractive features, the 2EZ19D5 Zener diode is an essential piece of equipment in electronics works.
