Schottky Barrier Diode (Schottky Barrier Diode), which is a low-power, high current, ultra-high-speed semiconductor devices, with a positive Pressure drop is 0.4V, the switching speed is very fast, the reverse recovery time is very short (2-10ns nanosecond), etc. The disadvantage is that the reverse leakage current is large, the pressure is low, generally less than 150V, mostly for low voltage applications.


Classification Schottky diodes are divided into: plug-in (DO-41) and patch (SOD, SOT) two packages. DO-41 package Schottky diode is usually used as high-frequency high-current rectifier diodes, freewheeling diodes or protection diodes. It has a single tube and a tube (double diode) type of two packages.

Schottky has three kinds of pin leads to the tube (the negative connection of the two tubes), the common (the positive connection of the two tubes) and the series (the positive pole of one diode is connected to the other diode).
