Question

Comparison between feedback and freewheeling diode

Answer 1

In case of inductive load the feedback diode is used .These diodes are used to provide discharging path for inductors. For resistive load,feedback diode are not required. ... Diodes in such mode is used as a diac function with a switching voltage of say, 0.7v if it is of silicon.
where As,
A flyback diode is a diode connected across an inductor used to eliminate flyback, which is the sudden voltage spike seen across an inductive load when its supply current is suddenly reduced or interrupted.
