Many, the same range as of transistor. Even more, since tunnel diode is the fastest semiconductor. With its negative slope and speed it is ideal for fast oscillators and receivers. With its hill it can be used as a memory. However it has a drawback - it cannot be integrated into large integrated circuit like transistors.
Because of that it is left only for special applications. I know they use it in oscilloscope horizontal synchronization to trigger an electron beam by the input signal. Some 30 years ago General Electric published an excellent book (about 700 pages) about tunnel diodes and its applications. I think not much has changed since.

Tunnel Diode Applications:
Tunnel diode is a type of sc diode which is capable of very fast and in microwave frequency range. It was the quantum mechanical effect which is known as tunneling. It is ideal for fast oscillators and receivers for its negative slope characteristics. But it cannot be used in large integrated circuits – that’s why it’s an applications are limited.
When the voltage is first applied current stars flowing through it. The current increases with the increase of voltage. Once the voltage rises high enough suddenly the current again starts increasing and tunnel diode stars behaving like a normal diode. Because of this unusual behavior, it can be used in number of special applications started below.
Oscillator circuits :Tunnel diodes can be used as high frequency oscillators as the transition between the high electrical conductivity is very rapid. They can be used to create oscillation as high as 5Gz. Even they are capable of creativity oscillation up to 100 GHz in a appropriate digital circuits.
Used in microwave circuits: Normal diode transistors do not perform well in microwave operation. So, for microwave generators and amplifiers tunnel diode are. In microwave waves and satellite communication equipments they were used widely, but now a day’s their uses is decreasing rapidly as transistor for working in wave frequency area available in market.
Resistant to nuclear radiation :Tunnel diodes are resistant to the effects of magnetic fields, high temperature and radioactivity. That’s why these can be used in modern military equipment. These are used in nuclear magnetic resource machine also. But the most important field of its use satellite communication equipments.
