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. The current increases with the increase of voltage. Low cost Low noise; Environmental immunity; Low power dissipation; Simplicity in fabrication Longevity; Disadvantages of tunnel diode: Low output voltage swing; Because it is a two terminal device, there is no isolation between input and output. Some disadvantages are reverse-biased operated so no current flows. Advantages of Tunnel Diodes It is a low noise device. Benefits or advantages of Tunnel diode Following are the benefits or advantages of Tunnel diode: ➨Current due to majority carriers in tunnel diode responds much faster to voltage changes. When the voltage is first applied current stars flowing through it. The tunnel diodes are heavily doped p-n junction diodes with negative resistance over a portion in The negative resistance property helps in the operation of tunnel diode. A tunnel diode or Esaki diode is a type of semiconductor diode that has effectively " negative resistance " due to the quantum mechanical effect called tunneling. It produces low noise, and their fabrication is also very simple. It was invented in August 1957 by Leo Esaki, Yuriko Kurose, and Takashi Suzuki when they were working at Tokyo Tsushin Kogyo, now known as Sony. ➨It has low power consumption. Die Tunneldiode, 1957 entdeckt vom japanischen Wissenschaftler Leo Esaki (deshalb auch Esaki-Diode genannt), ist ein Hochfrequenz-Halbleiterbauelement.

The tunnel diode is not as widely used these days as it was oat one time. At a tunnel diode, considering its advantages and disadvantages to discover whether it is. The tunnel diode is made by doping the semiconductor material ( Germanium or gallium arsenide) with a large number of impurities. Conversion of AC input voltage to the DC output voltage when AC voltage is applied to a diode is called as rectification. ➨Large current flows at small value of reverse voltage due to considerable overlap Applications of Diode. Characteristic of Tunnel Diode: A tunnel diode is a great conductor in the opposite direction. Following are the benefits or advantages of Tunnel diode: In the current I P known as peak current is corresponding to the voltage V P, the change in current to voltage (dI/dV) ratio stays 0. It has a very small size. It is ideal for fast oscillators and receivers for its negative slope characteristics. ➨Current due to majority carriers in tunnel diode responds much faster to voltage changes.
