Diodes - Zener - Single

The 2EZ100D2E3/TR8 is a commonly used Zener diode with a wide range of applications. As a Zener diode, it has a reverse breakdown voltage of 10V and a power rating of 500mW. It can be used in a broad range of applications, including voltage regulation, surge suppression, voltage clamping, line regulation, noise ltering and denoise.

Working Principle of 2EZ100D2E3/TR8

The working principle of a 2EZ100D2E3/TR8 is based on avalanche breakdown. It is a protective device that utilises the reverse-biased characteristic of the Zener diode. The Zener diode will break down when the reverse voltage exceeds the Zener voltage. When this occurs, the diode starts to conduct electricity in the reverse direction. As a result, the reverse voltage across the Zener diode remains constant, as long as the current remains below the maximum rating.

The Zener diode provides protection against short circuits and excessive voltages. A short circuit causes an increase in current, which in turn results in a sharp increase in voltage across the Zener diode. This forms a clamp across the short circuit, limiting the voltage increase. Similarly, if the input voltage is excessively high, the Zener diode will breakdown, limiting the voltage across the Zener diode in order to protect the circuits from overvoltage. As such, the Zener diode acts as a safety device.

In addition, the Zener diode can also be used for voltage regulation. When the input voltage is kept above the Zener voltage, the Zener diode acts like a simple diode, providing a fixed output voltage. This output voltage can be used to power other electronic components.

Conclusion

The 2EZ100D2E3/TR8 is a commonly used Zener diode with a wide range of applications, including voltage regulation, surge suppression, voltage clamping, line regulation, noise ltering and denoise. Working on the principle of avalanche breakdown, it provides protection against short circuits and excessive voltages, while also being able to satisfy constant voltage supply requirements.
