The Schottky diode (named after the German physicist Walter H. Schottky), also known as Schottky barrier diode or hot-carrier diode, is a semiconductor diode formed by the junction of a semiconductor with a metal. It has a low forward voltage drop and a very fast switching action.
Schottky diodes are used for their low turn-on voltage, fast recovery time and low-loss energy at higher frequencies. These characteristics make Schottky diodes capable of rectifying a current by facilitating a quick transition from conducting to blocking state.
The Schottky diode is measured in both forward And reverse directions. If the re a, the measurement in Figure 8-25 indicates that the tube is a silicon diode. If it is a germanium diode, the forward voltage reading should be less than 0.3V.
Like other diodes, the Schottky diode controls the direction of current flow in a circuit. However, unlike standard diodes, the Schottky diode is known for its low forward voltage and fast switching ability. This makes them an ideal choice for radio frequency applications and any device with low voltage requirements.
Advantages of Schottky diode :
1)High efficiency.
2)Fast recovery time so it can be mostly used in the application of high-speed switching.
3)Low junction capacitance.
4)The low forward voltage drop.
5)It can operate high frequency.
6)Schottky diode produces less unwanted noise than P-N junction diode.
7)High current density.
