Semiconductors and Diodes (A8204)

About this class



Learn the principles of AC/DC and solid-state theories. Digital electronic theory is also introduced.




Prerequisites


This lesson is designed for participants familiar with AC/DC theory, electrical safety, electrical print reading, electrical connections, and the proper use of electrical test instruments.

Description


This lesson presents the physical and electrical properties of different semiconductor material types and how current flows through each type. The lesson shows codes and symbols for diodes and how and zener diodes are also explained.

Objectives


Describe the physical and electrical properties and current flow of N-type and P-type semiconductor material. Understand the PN junction theory. Describe the codes and symbols that are used to identify a diode. Interpret schematic drawings and manufacturer??s markings for diodes. Test an unmarked diode to identify the anode and cathode. Explain how the operating characteristic curve represents diode operation in terms of the relationship between current and voltage. Explain how the operating characteristic curve indicates forward operating current in an AC circuit. Describe how zener diodes operate and how they are used to regulate voltage in a circuit.
