A Zener diode is a semiconductor component that permits current to flow both forward and backward. Zener diodes are used in clipper circuits, surge suppressors, reference elements, voltage regulation, and switching applications.A Zener diode is a unique kind of diode made to consistently permit current to flow "backwards" when a specific reverse voltage, also known as the Zener voltage, is applied. The breakdown voltage of the diode is the same as the load voltage. The series resistor limits the current flowing through the diode when it is conducting by lowering the excess voltage. The clipping circuits restrict a portion of the AC waveform in order to protect or shape the waveform. To reduce interference, these circuits are typically found in TV and FM transmitters. High currents are protected from damaging this Zener diode. This resistor helps guard against excessive current damage to the diode.
