What is a schottky rectifiers？
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.
Applications for Schottky Rectifiers:
Schottky rectifiers are ideal for output stages of switching power supplies. The very fast switching speed of Schottky rectifiers allows them to be used in very high frequency applications such as very low power signals and switching diode requirements of less than 100 picoseconds. Other applications include power management circuits and other various rectifier circuits.
