The application field of this diode is wide. It can be used in linear regulators, motor control systems, switching power supplies and consumer electronics.

Working Principle

The working principle of the GDZ2V2B-HE3-18 diode is based on the principle of electron tunneling, which is the fundamental nature of a diode\'s behavior. In order to understand this process, we must first look at the energy band structure of a diode. In semiconductor materials, there are two energy bands: the conduction band (E c ) and the valence band (E v ). Electron tunneling occurs when electrons in the conduction band tunnel through the barrier formed by the energy gap between the conduction band and the valence band.

In a Zener diode, when the voltage applied across the diode exceeds the Zener breakdown voltage of the device, electron tunneling takes place, resulting in a large current flowing through the diode. This current is known as the Zener current. With this diode, the voltage across it will remain constant as long as the current through it stays constant. This makes this type of diode very useful for regulating the voltage.

Conclusion

In conclusion, the GDZ2V2B-HE3-18 is a single-phase Zener diode with wide application in motor control systems, linear regulators, switching power supplies, and consumer electronics. The working principle of the diode is based on the electron tunneling process which results in the Zener current. This diode can also serve as a voltage regulator as it can maintain a constant voltage across it as long as the current stays constant.
