A flyback diode is any 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. It is used in circuits in which inductive loads are controlled by switches, and in switching power supplies and inverters. WebOct 19, 2016 · First, you have the diode snubber. This is used in systems running on DC current, and it utilizes a rectifier diode as the snubber. It basically works like this — the diode is wired in parallel with the load (like an electric motor), but it is set up so that it does not conduct under normal use. cygnal integrated products inc
