Discrete Semiconductor
A semiconductor device is one made of silicon or any number of other specially prepared materials designed to exploit the unique properties of electrons in a crystal lattice, where electrons are not as free to move as in a conductor but far more mobile than in an insulator.
A Discrete Semiconductor is one that is contained in its own package rather than being built on a common semiconductor substrate with other components, as is the case with ICs, or integrated circuits. Thus, "discrete semiconductor circuits" are circuits made up of individual semiconductor components that are connected together on a circuit board or terminal strip.
