What are the 3 most common semiconductor devices?

  • Metal Oxide Semiconductor Field-effect Transistor (MOSFET) – These are used for switching or amplifying signals. They are the most commonly used semiconductor device due its ability to change conductivity with the amount of voltage that is applied. 
  • Diode – These are used as a one-way valve in a circuit which allows current to flow in one direction.  
  • Transistors – These are used to control, amplify or switch electrical signals and power.
