Provide two designs of shunt regulators utilizing the 1N5235 zener diode, which is specified as follows: VZ = 6.8V and rz = 5ohm for IZ = 20mA; at IZ = 0.25mA (nearer the knee),  rz = 750ohm. For both designs, the supply voltage is nominally 9V and varies by1V . For the first design, assume that the availability of supply current is not a problem, and thus operate the diode at 20mA. For the second design, assume that the current from the raw supply is limited, and therefore you are forced to operate the diode at 0.25mA. For the purpose of these initial designs, assume no load. For each design find the value of R and the line regulation.

Applications of Diode

Diodes are the two-terminal components used in many electronics and electrical applications. The current flow in such components is unidirectional. A diode provides very low resistance in one direction, but in the opposite direction, it provides very high resistance. One of the common functions of a diode is to allow the current flow in the forward direction and resist the current flow in the reverse direction. However, besides this simple functioning of diodes, diodes generally show non-linear current-voltage characteristics. For instance, the semiconductor diodes conduct current only when a certain threshold voltage, or preferably cut-off voltage is reached in the forward direction. They are known as forward-biased diodes. Also, upon reaching a certain voltage, known as the breakdown voltage, the high resistance provided by diodes in the reverse direction reaches a low resistance value.
