Advantages and disadvantages of varactor diode

The diode whose internal capacitance varies with the variation of reverse voltage such type of diode is known as the varactor diode. The varactor diode always works in reverse bias and it is voltage dependent semiconductor device. It is used in storing the charge. Here this article gives information about the advantages and disadvantages of varactor diode to know more detailed about it.

Advantages of varactor diode:
  • It generates less noise as compared to other PN junction diode
  • The power loss due to noise is low 
  • It is portable due to the small size and  also a lightweight
  • Reliability
  • It is economical
  • Low cost
  • It has a small size 
  • It is reliable you can use it to vary a capacitance
Disadvantages of varactor diode:
  • These diodes are specially designed to work in the reverse-biased mode. Hence they are not useful when operating them in the forward bias mode
