Electronic Technology - ELECT 139

Diodes and Transistors

3 Credit Hours
1 Lecture Hours
2 Laboratory Hours

Course Description

This course will introduce the students to various semiconductor devices starting with a discussion of internal construction, followed by circuit configurations, applications and troubleshooting techniques. Diodes will be discussed first and will include signal, rectifier, Zener and light emitting types. Transistor material will cover NPN and PNP bipolar types, J type FETs, enhancement and depletion MOSFETs. Finally, transistor switching circuits will be examined.
