Applications of Zener diode.

Applications of Zener Diode-
(i) It is used as a voltage regulator which gives a constant voltage from a source whose voltage may vary over suficient range.
(ii) It is used as a fixed reference voltage in transistor biasing circuits.
(iii) In waveshaping circuit, zener diode is used as limiter.
(iv) A Zener diode protect a meter movement or circuit against damage from an accidental application of excessive voltage.
(v) zener diode can produce a sudden change from low current to high current, so it is useful for switching operation.
