A bistable semiconductor device comprising three or more junctions which is normally a nonconductor until the application of a signal to a gate terminal, at which time the device switches to the conductive state. Includes devices capable of being switched back to the nonconductive state upon application of a different signal to the same or another gate terminal. May or may not include mounting hardware and/or heatsink. For solid state devices which are responsive to visible or infrared radiant energy, see SEMICONDUCTOR DEVICE, PHOTO.
SEMICONDUCTOR DEVICE ASSEMBLY
A grouping of two or more semiconducting devices such as LIGHT EMITTING DIODE; SEMICONDUCTOR DEVICE, DIODE; SEMICONDUCTOR DEVICE, PHOTO; SEMICONDUCTOR DEVICE, THYRISTOR; and/or TRANSISTOR mounted on a common mounting or mounted on each other. The devices must be separable and each item must be capable of functioning in accordance with its given name. For assemblies consisting of semiconducting devices permanently cased, encapsulated, or potted together to form a single unit, see RECTIFIER, SEMICONDUCTOR DEVICE, UNITIZED and SEMICONDUCTOR DEVICES, UNITIZED. Excludes SEMICONDUCTOR DEVICE SET; MICROCIRCUIT ASSEMBLY; and MICROCIRCUIT SET. See also ABSORBER, OVERVOLTAGE.
