Because of their characteristics, zener diodes are used in numerous circuitries for stabilizing and limiting electrical voltages. In forward direction, they behave like normal diodes. In reverse direction, resistance drops off considerably after the voltage exceeds a certain value, the so-called breakdown voltage. The voltage does not increase by much after that, even if the electric current is increased.
