CUT-OFF (ELECTRONICS)

In electronics, the term 'Cut-off' identifies a state of negligible electrical conduction which is proper of several types of electronic components when a control parameter (which usually is a well defined voltage or electric current, but could also be an incident light intensity or a magnetic field strength) is lowered under a fixed value called 'conduction threshold' or simply 'threshold'. The transition from normal conduction to cut-off can be more or less sharper, depending on the type of device considered, and also the speed of this transition varies considerably.
