Schottky Rectifier

Schottky rectifiers have been used for several years in the power supply industry. The primary advantages are switching speeds that approach zero time and very low forward voltage drop. The reverse recovery time of Schottky diodes provides extremely fast recovery characteristics. What little reverse recovery time they exhibit is dictated by their capacitance instead of minority carrier recombination such as in conventional PN junction rectifiers. This offers very little reverse current overshoot when switching the Schottky from a forward conducting mode to a reverse blocking state.
