What is a Fast Rectifier?

Rectification is the most popular use for diodes. Fast rectifiers convert alternating current (AC) to direct current (DC). They only allow one-way flow of electrons. Rectifiers have many uses and are often found serving as components of high-voltage direct current power transmission systems and DC power supplies. Fast rectifier diodes feature very low reverse recovery time, very low switching losses and low noise turn-off switching.
Types of Fast Rectifiers
There are several different kinds of fast rectifiers. At Topdiode we offer many of the most common types categorized by maximum average rectified current, maximum reverse recovery time, maximum reverse current, maximum reverse voltage, packaging type and forward voltage. The most common sizes for forward voltage are 1.1 V, 1.2 V and 1.3 V.
 Applications for Fast Rectifiers:
Fast rectifier diodes are found in strobe applications that require high surge resistance as well as in the industrial, commercial and automotive sectors. High voltage resistance fast rectifier diodes, which are ideal for use in switching power supplies of all types, feature fast switching speeds along with improved efficiency and reduced loss. Fast rectifiers are also used in PDPs (sustain circuits) and PFC circuits. Also, detectors of radio signals serve as rectifiers.
