Schottky diode Schottky diode, also known as Schottky barrier diode (SBD for short), is a low-power, ultra-high-speed semiconductor device. The most notable feature is that the reverse recovery time is extremely short (can be as small as a few nanoseconds), and the forward voltage drop is only about 0.4V. It is mostly used as high-frequency, low-voltage, high-current rectifier diodes, freewheeling diodes, and protection diodes. It is also useful as rectifier diodes and small-signal detector diodes in microwave communication circuits. It is more common in communication power supplies, frequency converters, etc.

A typical application is in the switching circuit of the bipolar transistor BJT, by connecting the Shockley diode to the BJT to clamp, so that the transistor is actually close to the off state when it is in the on state, thereby increasing the switching speed of the transistor. This method is the technique used in the TTL internal circuits of typical digital ICs such as 74LS, 74ALS, 74AS, etc.

The biggest feature of Schottky diodes is that the forward voltage drop VF is relatively small. In the case of the same current, its forward voltage drop is much smaller. Plus it has a short recovery time. It also has some disadvantages: the withstand voltage is relatively low, and the leakage current is slightly larger. It should be considered comprehensively when choosing.
