WebSchottky diodes are also known as Schottky barrier diodes or hot-carrier diodes. They consist of a junction between a metal layer and a semiconductor element. The metal layer, a cathode, is heavily occupied with conduction-band electrons. The semiconductor element, an anode, is a lightly doped N-type semiconductor. WebThe diode conducts almost no current in the high resistance direction, i.e. when the Pregion is made negative and the N-region is made positive. Now the holes and electrons are drained away from the junction, causing the barrier potential to increase. ...

Schottky rectifiers will be faster than the "ultra fast" rectifiers. this is the reason that some companies have developed 200, 400 volt Schottky diodes for use in multi megahertz power supplies. WebCJ is the junction small signal capacitance of the diode at a specified reverse voltage. Normally, CJ is a monotonically decreasing function of VR, as can be seen in the diode datasheet figure entitled “Junction Capacitance vs. Reverse Voltage.” With SiC diodes at high voltages, the capacitance will become constant, independent of voltage.
