WebMay 29, 2009 · In fly back protection the diode does not have to be rated for continuous current. The fly back pulse is just microseconds long and most diodes have a surge current rating far in excess of there continuous ratings. However the reverse voltage rating should be looked at closely as the fly back pulse can reach 4X the coil voltage rating. WebFigure 1 shows a flyback converter operating in continuous conduction mode (CCM) and discontinuous conduction mode (DCM) with several parasitic components, such as pri …
