A diode is a device that allows current flow through only one direction. That is the current should always flow from the Anode to the cathode. 

Applications of Diode

  • Can be used to prevent the reverse polarity problem
  • High-Frequency Inverters
  • Used as a protection device
  • Current flow regulators
  • Polarity Protection applications
