Virginia’s CTE Resource Center

Describe the characteristics, operation, and applications of basic semiconductor devices.

Definition

Description should include
  • characteristics of basic semiconductor devices
  • operation of basic semiconductor devices (used to switch, amplify, and control direction of current flow)
  • diode construction techniques
  • transistor construction principles
  • real-world applications of integrated circuits using diode and transistor elements.

Process/Skill Questions

  • What are the electrical characteristics of semiconductor components?
  • What are the advantages and disadvantages of semiconductor devices?
  • How do the components operate, and what are their applications?
  • How are differences in reverse current (IR), peak inverse voltage (PIV), maximum forward current (IF Max), and reverse voltage important when selecting a replacement diode?
  • What is implied by different values of forward voltage drop (EF) in diodes?
  • How are forward bias and reverse bias similar/different?
  • What is the relationship between the depletion region, barrier voltage, and biasing voltage?
  • What is the difference between peak-reverse voltage and peak-inverse voltage (PIV)?
  • How are collector, emitter, and base similar/different to source, gate, and drain?
  • What is the difference between depletion and enhancement mode metal-oxide-semiconductor field-effect transistor (MOSFETs)?
