Discrete semiconductor products include individual transistors, diodes, and thyristors, as well as small arrays of such composed of two, three, four, or some other small number of similar devices within a single package. The most common and widely known is the MOSFET (metal-oxide-semiconductor field-effect transistor). They are commonly used for constructing circuits with considerable voltage or current stress, or for realizing very basic circuit functions.
