What is a discrete semiconductor? A discrete semiconductor is a material/device that has an electrical conductance between an insulator and a conductor. A semiconductor can conduct electricity but only partially. This fundamental characteristic provides a foundation for modern electronic devices. In 1901, Jagadish Chandra Bose invented what he called "cat whiskers," a point-contact semiconductor rectifier used for detecting radio waves.
What does a discrete semiconductor do? Classes of crystalline solids are intermediated in electrical conductivity between a conductor and an insulator.
Common materials used for semiconductors The most common semiconductor material used within electronics is silicon, which is a term that has become ubiquitous to describe PCB semiconductor devices as a whole. Common semiconductor devices Discretes: A device with an element. Examples include transistors like mosfets, diodes, TRIACS, and LEDs. Integrated circuits or ICs: Devices that incorporate several circuit elements into the whole package. Examples include microcontrollers, microprocessors, analog to digital converters, operational amplifiers, and voltage regulators. Where are semiconductors used?
