Advantages and disadvantages of Tunnel diode

One of the main reason for the early success of the tunnel diode was its high speed of operation and the high frequencies it could handle. Here this post gives information about the advantages and disadvantages of the Tunnel diode to know more detailed about it.

Advantages of tunnel diode:
  • Low cost
  • Low noise
  • High speed
  • Fabrication is also very simple
  • Fast response
  • Moderate in operation
  • Low power
  • Longevity
  • Ease of operation
  • Environmental immunity
  • Insensitive to nuclear radiation
Disadvantages of tunnel diode:
  • The voltage range, which can be operated properly in around 1 volt or below
  • Being two terminal device, it provides no isolation between output and input circuit
  • The power output levels of tunnel diode are restricted to only a few milliwatts because the applied DC potential must be less than bandgap potential of the diode
