Schottky diodes are divided into two packaging forms: lead and surface mount (SMD). Schottky diodes with lead packages are usually used as high-frequency high current rectifying diodes, freewheeling diodes or protection diodes. It has two packaging forms: single tube type and pair tube (double diode) type. There are three pin lead out methods for Schottky pairs: common cathode (the negative electrodes of the two tubes are connected), common anode (the positive electrodes of the two tubes are connected), and series (the positive electrode of one diode is connected to the negative electrode of the other diode).
Surface packaged Schottky diodes are available in single tube, double tube and three tube packages, and there are a ~ 19 pin lead out methods.
