Schottky Diodes & Rectifiers

A Schottky Diode is sometimes referred to as a Barrier Diode or a Hot Carrier Diode. The Schottky is a single type of electronic component which is a semiconductor. It has fast switching action with an accompanying low forward voltage drop, when current flows through the diode, a small voltage drop happens across the diode terminals.

A standard diode has a voltage drop between 0.6 and 1.7 volts whereas a Schottkys drop is between 0.15 and 0.45 volts. This lower voltage drop facilitates a high switching speed as well as improved system efficiency.

What are Schottky Diodes used for

  • They are used for the voltage clamping of applications, also as a preventative of transistor saturation
  • They can be used as rectifiers (in power supplies)
  • A good element to use in applications that are sensitive and efficiency
  • To prevent batteries from discharging
  • Solar panels and grid connected systems

Why should I use a Schottky

  • They feature a low turn voltage between 0.15 and 0.45 volts
  • A fast recovery time, resulting in a small amount of stored charge that can then be used for high speed switches
  • The low junction capacitance occupies a small space, after the results given from the wire point contact the silicon, the capacitance levels are also very small
  • Higher efficiency
  • Integrated guard ring for stress protection

What is a Rectifier Diode

A rectifier diodes main purpose is to rectify alternating currents. It's used to flow a current through a circuit in one direction, in contrast to elements such as resistors and rectifiers current has a non-linear relationship to the voltage across it. The diode will be forward bias when positive voltage is being applied and will do its best to operate as a short circuit and allow the current to flow through the diode freely. Its main task is to convert an alternating current (AC) into a direct current (DC) through the application of rectifier bridges. A rectifier diode can sometimes be used as a Schottky Rectifier.
