Ultra Fast Recovery Diodes

Microsemi PPG offers five series of discrete diode products: a new DL series low VF ultra-soft recovery, the medium speed medium VF

D series, the high speed DQ series, the very high speed DS series, and the silicon Schottky S series. These series of diodes are designed

to provide high quality solutions to a wide range of high voltage, high power application requirements, ranging from fast recovery for

continuous conduction mode power factor correction to low conduction loss for output rectification. Distinguishing features, technology

used, and applications for each product family are summarized in the table below.
