Let's define our terms more precisely, here are the standard definitions in physics: disruptive discharge Also found in: Thesaurus, Medical, Legal, Encyclopedia, Wikipedia. Related to disruptive discharge: Disruptive discharge coil disruptive discharge n (General Physics) a sudden large increase in current through an insulating medium resulting from failure of the medium to withstand an applied electric field Collins English Dictionary – Complete and Unabridged, 12th Edition 2014 © HarperCollins Publishers 1991, 1994, 1998, 2000, 2003, 2006, 2007, 2009, 2011, 2014 disruptive discharge noun Electricity. the sudden, large increase in current through an insulating medium resulting from complete failure of the medium under electrostatic stress . If there is another definition for the term, please list it here so that everyone is on the same page as this term has been bandied about a lot lately without a consensus. Maybe this can help provide some agreement on it's usage. Regarding a FET as a "disruptive discharge" device, it would seem to imply from the definition that the FET would be capable of a single current discharge leading promptly to it's failure. FET's have been used for many decades now in driving coils and transformers. These are the common semiconductor device of switchmode power conversion, which has been well explored, however, I have never seen it referred to as a "disruptive discharge" device. Regards ;
