TYPES OF TUNNEL DIODE

Types of Tunnel Diodes

Tunnel diodes come in different types based on how they are built and the materials that were used to make them.

  1. Single-Well Tunnel Diode: This kind of diode has a negative differential resistance and is used in circuits for amplifiers and oscillators.
  2. Double-Barrier Tunnel Diode:This diode is used in millimeter-wave generators because it can work at higher frequencies.
  3. Superlattice Tunnel Diode: This is used to achieve more exact control over the tunneling process and can lead to better performance
  4. A tunnel diode that resonates:This is the Esaki inter-band tunnel diode. It is an addition to the normal tunnel diode and is used for tasks that need higher frequencies.

 

Advantages of Tunnel Diode

  • Extremely small.
  • Simple to make.
  • Not expensive.
  • Low electricity use.
  • Live a long time.
  • Not too loud.
  • Fast moving.

 

Disadvantages of Tunnel Diodes

  • Not enough proper DC separation.
  • Less change in power.
  • Not able to be made in large amounts.

 

Applications of Tunnel Diodes

  • Tunnel diodes can switch on and off quickly, which is why they are used in microwave applications.
  • The II relaxation oscillator circuit makes use of it.
  • Used to store logic and memory.
  • It is used in FM tuners.
