Zener Diodes

Zener diodes are among the basic building blocks of electronic circuits. Their basic function is to stabilize the voltage within the system to limit or by pressing the direction of current flow changed, as soon as a defined blocking voltage has been reached. This breakthrough voltage goes hand-in-hand with two different effects, which require a more precise differentiation of the Zener diodes or the Z-diodes:

  • Zener diodes: have a blocking voltage below 5 volts, if this is exceeded one speaks of the Zener effect (named after its discoverer Clarence Melvin Zener).
  • Avalanche diodes: have a blocking voltage of 5 volts, if this is exceeded, the avalanche effect occurs.
  • Z-Diodes: includes all diodes with a blocking voltage.

At a blocking voltage between 5 and 6.5 volts, the Zener effect and the avalanche effect occur simultaneously, while above 6.5 volts only the avalanche effect comes into play.

Z-diodes are mainly used to stabilize pulsating DC voltages or to set reference voltages for circuits with low and relatively constant current consumption. Voltage regulators should be used for extreme current fluctuations or larger current flows.
