Semiconductor Devices

This text discusses the different types of semiconductor devices that are used in electronics today. The most common types of semiconductor devices are bipolar junction transistors (BJTs), junction field-effect transistors (JFETs), metal-oxide semiconductor field-effect transistors (MOSFETs), and insulated-gate bipolar transistors (IGBTs).

Questions

• What are the different types of semiconductor devices?
• How do BJTs work?
• How do JFETs work?
• How do MOSFETs work?
• How do IGBTs work?

Answers

• The different types of semiconductor devices are BJTs, JFETs, MOSFETs, and IGBTs.
• BJTs work by controlling the flow of current between the emitter and collector through the base.
• JFETs work by controlling the flow of current between the source and drain through the gate.
• MOSFETs work by controlling the flow of current between the source and drain through the gate, which is insulated from the semiconductor material.
• IGBTs are a type of BJT that is used to control high-power applications.
