discrete (semiconductor) device

A semiconductor device that is specified to perform an elementary electronic function and is not divisible into separate components functional in themselves.

NOTE 1 Diodes, transistors, rectifiers, thyristors, and multiple versions of these devices are examples. Other semiconductor structures having the physical complexity of integrated circuits but performing elementary electronic functions (e.g., complex Darlington transistors) are usually considered to be discrete semiconductor devices.

NOTE 2 If a semiconductor device is not considered to be an integrated circuit in both complexity and functionality, it is considered to be a discrete device.
