Introduction to 1n5822

• 1n5822 is a Schottky diode, also known as a hot-carrier diode, mainly used in fast-clamp diode switching applications. It is made up of semiconductor material and carries low forward drop voltage.
• The small voltage drop occurs across the diode terminals when current flows through the diode.

• Though both normal diode and Schottky require 2V DC source to power these components, the Schottky diode utilizes 0.3V out of 2V, leaving only 1.7V to power the diode while the normal diode uses 0.7V out of a 2V DC source, leaving 1.3V to power the diode.

• Schottky diode is also called hot-carrier diode because electrons carry low energy when they are present on the semiconductor material in an unbiased condition.
• This results in the formation of a barrier through which electrons cannot flow, the reason it’s also called the Schottky Barrier diode or hot carrier diode.

1n5822 Schottky Diode Construction

• The 1n5822 Schottky diode is constructed by the combination of semiconductor material with metal, forming a barrier.
• The metals used in this case are tungsten, chromium, platinum, molybdenum, and silicides.
• And the n-type silicon is the commonly used semiconductor material. The resulting diode carries a very low forward voltage drop and is capable of very fast switching.
• The metal used behaves as an anode or positive side of the diode and n-type semiconductor (with a colored band) is used as a cathode or negative side of the diode. In this case, the conventional current will flow from the anode metal side to the cathode semiconductor side.
• The forward voltage of the diode depends on the nature of the metal and semiconductor you pick for the formation of that diode.
• Though both n-type and p-type semiconductors are used to form a Schottky diode, the p-type semiconductors result in very low forward voltage compared to n-type semiconductors, the reason p-type semiconductors are rarely used to form the Schottky diodes.

• In Schottky diodes less energy is wasted as heat as they possess low forward voltage drop, making them an ideal pick for the applications that are sensitive to efficiency.
• Plus, they are also used in photovoltaic systems to keep the batteries from discharging in solar panels at night.
• A control circuit or MOSFET can replace Schottky diodes in cases where less power dissipation is needed.
