Unlike normal diodes, which allow only forward current, Zener diodes will allow a current to move in reverse when voltage exceeds a specified value, preventing breakdown of the diode. Because of this ability to reverse a portion of the current, Zener diodes offer several advantages in a circuit that normal diodes don't. The idea behind the reverse current used in this diode was proposed by Dr. Clarence Melvin Zener in 1934.
