WebOct 15, 2013 · Take a look at this diagram from the Wikipedia page about flyback diodes: http://en.wikipedia.org/wiki/File:FlybackExample.GIF In figure 1, the switch is closed and current flows through the inductor, eventually reaching a steady state. The upper terminal of the inductor is at a positive voltage relative to the lower terminal. WebAug 12, 2013 · The clamp diode is normally reversed biased but when there is an opposite current flowing it will protect the power supply as well as other components in the circuit. The negative voltage will be connected to the power supply but since the switch is opened on the positive side, no current will flow. The second illustration is a bit more confusing.

"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. " - Flyback diode wikipedia
