What are the attributes and functions of Schottky diodes?

In the production of electronic products, a material will be used, which is also known as the "source of life" in the electronics industry, this material is the Schottky diode, also known as the Schottky barrier diode (SBD), which is a low-power, ultra-high-speed semiconductor device. The most notable feature is the extremely short reverse recovery time (which can be as small as a few nanoseconds) and the forward conduction voltage drop of only about 0.4V. It is mostly used as high-frequency, low-voltage, high-current rectifier diode, freewheeling diode, protection diode, and is also used as rectifier diode and small signal detection diode in microwave communication and other circuits.

Schottky diodes are more common in communication power supplies, inverters, etc.

A typical application is that in the switching circuit of the BJT BJT, a Shockley diode is connected to the BJT to clamp the position, so that the transistor is actually in a very close cut-off state when it is turned on, so as to increase the switching speed of the transistor. This method is a technology used in the TTL internal circuits of typical digital ICs such as 74LS, 74ALS, and 74AS.

The most important feature of Schottky diodes is that the forward voltage drop VF is relatively small. At the same current, its forward voltage drop is much smaller. In addition, it has a short recovery time. It also has some disadvantages: the withstand voltage is relatively low, and the leakage current is slightly larger. When choosing, it should be considered thoroughly.

It is used as a Schottky diode and a small signal detection diode in the circuit. It is more common in communication power supplies, frequency converters, etc. FYI. One application I know is in the BJT switching circuit, by connecting a Shockley diode on the BJT to clamp the position, so that the transistor is actually in a very close to the cut-off state when the transistor is turned on, so as to improve the switching speed of the transistor. This method is the technology used in the internal circuit of 74LS, 74ALS, 74AS and other typical digital ICTTL.3. Crystal diode Crystal diode is often represented by "D" plus number in the circuit, such as: D5 represents the diode numbered 5.

1. Function: The main characteristic of the diode is unidirectional conductivity, that is, under the action of forward voltage, the on-resistance is very small, and under the action of reverse voltage, the on-resistance is very large or infinite. Because Schottky diodes have the above characteristics, they are often used in rectifier, isolation, voltage regulation, polarity protection, coding control, FM modulation and noise suppression circuits in cordless telephones. The crystal diodes used in telephones can be divided into rectifier diodes (such as 1N400) according to their functions
