Zener diode is a diode which is used in its break down region. The diode is kept reverse biased in a circuit, and so it does not allow current to pass until the voltage is greater than the breakdown voltage of the zener.
What is a light-emitting diode? A diode is a two-terminal semiconductor device. It can be thought of as an electronic valve that only allows current to flow in one direction. The symbol for the diode is shown in the lefthand picture of figure 5. The symbol is shaped like an arrow that indicates the direction in which current may flow. The terminal marked with a positive sign is called the anode and the terminal marked with a negative sign is called the cathode. The righthand picture depicts the physical device.
