What Is a Schottky Rectifier?
Diodes are one of the basic electronic components, like transistors and ICs, and are also called active components, while resistors and capacitors are called passive components. They are made of semiconductors such as silicon, germanium, and gallium arsenide. Among these, diodes using silicon as the material are silicon diodes, and one type of diode is a Schottky rectifier.
Unlike silicon diodes for general use, which are made by joining a P-type semiconductor and an N-type semiconductor, the Schottky rectifier uses a combination of a semiconductor and a metal such as molybdenum, utilizing a potential barrier generated by the contact between the two.
Applications of Schottky Rectifiers
Schottky rectifiers are mainly used in power supply circuits in the electrical and electronic circuits of various devices.
The commercial power supply provides an alternating current. On the other hand, the various control circuits in electronic equipment are designed for direct current circuits.
In order to convert the incoming AC current to DC, the Schottky rectifier is used for its property of flowing the current in a certain direction. This is called the rectification function.
Schottky rectifiers also have the function of detection, which extracts video and audio signals from broadcast radio waves such as television and radio.
Principle of Schottky Rectifiers
Silicon diodes, including Schottky rectifiers, are semiconductors like transistors and ICs.
A semiconductor is a material with properties intermediate between those of a conductor, such as a metal, which conducts current well, and an insulator, such as a plastic, which does not conduct current.
A Schottky rectifier looks like an ordinary rectifier diode, but it has several characteristics. Unlike general rectifier diodes, Schottky rectifiers are made by bonding a semiconductor and a metal.
The first feature is that the forward voltage is small. While the forward voltage of a general rectifier diode is approximately 0.6 to 0.7 V, that of a Schottky rectifier is 0.2 to 0.3 V. Therefore, the Schottky rectifier generates as little voltage drop as possible. Therefore, Schottky diodes are effective when used in areas where voltage drop is not desired.
In addition, the reverse recovery time, which is the time from when the diode is turned on to when it is completely turned off, is extremely short. It is often used in high-frequency circuits, for example, in detection to extract video and audio signals. On the other hand, since the reverse current (leakage current) is more significant than that of general diodes, thermal runaways may cause destruction.
When a large amount of forwarding current is applied, the reverse current increases. This increase in backward current generates additional heat, resulting in a loop that may destroy the device in the worst case. Therefore, circuit design must fully consider the disadvantages and advantages of Schottky rectifiers.
