Two or more discrete semiconductor devices such as diode(s) and/or transistor(s), permanently cased, encapsulated, or potted together to form an inseparable unit. Excludes:devices having one or more components other than semiconductor devices. The individually distinct devices forming the unit may be internally connected. The unit in itself does not perform a complete specific function and cannot be assigned a more definite item name. It may include or consist of inseparable matched pairs. May or may not include mounting hardware and/or heatsink. For interconnected items arranged in stack(s), see rectifier, semiconductor device. For items formed on or within a semiconductor material substrate, formed on an insulating substrate or formed on a combination of both of these types, see microcircuit (as modified). Excludes:network (as modified); absorber, overvoltage; semiconductor device set; and semiconductor device assembly. Do not use if more specific name applies.
