1 Answer

Answer :

image

Applications:

One of the important application of a tunnel diode is in high speed computers where the switching times in the order of nanoseconds or picoseconds are desirable.

A tunnel diode can be used at such high speeds as a result of the electrons “punching through” at velocities that far exceed those in conventional diodes.

The punching through takes place due to narrow depletion region.

Some other applications are :

1. In digital networks.

2. As a high speed switch.

3. As a high frequency oscillator.
