2EZ47D5E3/TR8 Application Field and Working Principle

2EZ47D5E3/TR8 is a type of single Zener diode, mainly used for voltage regulation and protection purposes. It is widely adopted nowadays in a variety of applications including radio and communication systems. The main feature of this kind of diode is the ability to regulate or stabilize a DC circuit voltage even when it is subjected to a wide range of input voltages and temperatures. In this article, we will look at the application field and working principle of 2EZ47D5E3/TR8.

Application Field

2EZ47D5E3/TR8 diodes are primarily used in high voltage regulating, voltage clamping and protection circuits. They are often employed in the protection of telephone lines, power supplies and other sensitive electronic circuitries. Moreover, it is also preferred for stabilizing the output voltage of any isolated AC-DC converter.

Working Principle

When the forward current (Iz) of the diode is below the breakdown voltage (Vz), the device works as a regular diode and behaves like an open switch. However, when the forward current (Iz) exceeds the breakdown voltage (Vz), the diode starts to conduct in a reverse direction and behaves like a closed switch. The breakdown voltage (Vz) in the 2EZ47D5E3/TR8 is specified to be 15V.

Furthermore, the Zener diode is designed to limit the applied voltage to a safe level when the voltage applied to the diode is higher than the breakdown voltage Vz. This is why Zener diodes are often used to stabilize the voltage in so-called ‘voltage regulators’. This operation is based on the property of the device, known as the Zener Effect. As a result of this effect, the device can dissipate current to maintain a voltage within a certain range.

In addition, the device is able to protect any circuit from high voltage overshoots in the case of high frequency applications, because the device limits the voltage swing to the value of Vz+Vz. Finally, the Zener diode can also be used in wave form shaping, because of its capability to control the amplitude of AC waveforms.

Conclusion

In conclusion, the 2EZ47D5E3/TR8 is an efficient and reliable single Zener diode with a breakdown voltage of 15V. It is mainly used for voltage regulation and protection purposes, and it can be used in a variety of applications such as radio and communication systems and isolated AC-DC converters. The Zener diode works by limit the voltage applied to the device below its breakdown voltage and dissipating current to maintain voltage within a certain range.
