This package contains different types of Zener Diodes, each with different voltage rating, from 3.3V to 30.0V ratings.
A Zener diode is a specific kind of diode that, not at all like a typical one, enables current to stream from its anode to its cathode, as well as in the reverse direction, when the supposed "Zener voltage" is reached. Zener diodes have an exceptionally doped p-n junction. Typical diodes will likewise fail with voltage flowing in the reverse direction, however the voltage and sharpness of the knee are not too characterized concerning a Zener diode. Additionally ordinary diodes are not intended to work in the breakdown state, but rather Zener diodes can dependably work in this state.
Zener diode was named after Clarence Melvin Zener, who found the Zener impact. Zener reverse breakdown is because of electron quantum burrowing caused by a high quality electric field. In any case, numerous diodes depicted as "Zener" diodes depend rather on avalanche breakdown. Both breakdown sorts are utilized in Zener diodes with the Zener impact prevailing under 5.6 V and avalanche breakdown above.
Zener diodes are broadly utilized as a part of electronic appliances of various types and are one of the essential building blocks of electronic circuits. They are utilized to create low power stable supply rails from a higher voltage and to give reference voltages to circuits, particularly stable power supplies. They are likewise used to shield circuits from over-voltage, particularly electrostatic release.
