APPLICATIONS OF SCHOTTKY DIODE

Working of a Schottky Diode

  • The process is based on the idea that electrons in different materials have different potential energies.
  • Electrons in N-type semiconductors have higher potential energies than electrons in metals.
  • When these two come together, electrons move in both directions across the region where the metal and semiconductor meet.
  • A charge is put on the Schottky so that the metal is more positive than the semiconductor.
  • The voltage works against the built-in potential, which makes it easy for the current to move.

 

Applications of Schottky Diodes

  • Because of their unique qualities, Schottky diodes have been useful in the electronics industry, which has found many uses for them in diode rectifiers. Here are some of the main places where it is used a lot.

 

RF mixing and detector diodes

  • The Schottky diode makes up its radio frequency functions because it can switch quickly at the highest level and handle the highest frequency.
  • There are Schottky barrier diodes that can be used to make high-performance diode rings.

 

Power rectifier

  • The Schottky barrier diodes can also work as rectifiers with a lot of power.
  • This type of PN junction diode wastes less power than most because it has a high density of current and a low voltage drop.

 

Power or OR circuits

  • We could use this diode in situations where two different power sources are used to power a load, like in a battery supply.
  • It's important that the power from the source doesn't mix with any other power.

 

Solar Cell Applications

  • Most of the time, portable batteries (mostly lead-acid batteries) are connected to solar cells so that they can get power all the time.
  • Solar cells wouldn't be able to handle the reversed charge, so a diode would be used in a pattern that matches the solar cells.

 

Advantages of Schottky diodes

  • The advantages of the Schottky diode are as follows:
  • This means that the diode's capacitance is low because its depletion area is very small.
  • It doesn't take long for the diode to go from ON to OFF, which is called healing time.
  • The diode has a high current density because the depletion area is very small.
  • The diode's turn-on voltage is very low, at 0.2 to 0.3 volts.

 

Disadvantages of Schottky diodes

  • One potential drawback associated with Schottky diodes is their relatively high reverse saturation current.
