Introduction to Transistors

COURSE NO: E04-010
PDH CREDIT: 4
COURSE PROVIDER: A. Bhatia
Introduction to Transistors
Course Highlights

This online engineering PDH course provides a basic understanding of the physical concepts needed to understand the semiconductor fundamentals of semiconductor devices.

 

A transistor is a small electronic device that amplifies a signal or can turn electricity on or off.  Invented in 1948 at Bell Labs, transistors have become the key ingredient of all digital circuits, including computers. A transistor consists of three layers of silicon or germanium semiconductor material.  Impurities are added to each layer to create a specific electrical positive or negative charged behavior.  There are essentially two basic types of point-contact transistors: the NPN transistor and the PNP transistor, where the N and P stand for negative and positive, respectively. The only difference between the two is the arrangement of bias voltages. To understand how a transistor works, you have to understand how semiconductors react to an electric potential.

 

This 4 PDH online course is applicable to students, professional engineers, service technicians, energy auditors, operational & maintenance personnel, facility engineers who are interested in gaining a better understanding in transistors.

Learning Objectives

This PE continuing education course is intended to provide you with the following specific knowledge and skills:

  • Define the term transistor and give a brief description of its construction and operation
  • Explain how the transistor can be used to amplify a signal
  • Name the four classes of amplifiers and give an explanation for each
  • List the three different transistor circuit configurations and explain their operation
  • Identify the different types of transistors by their symbology and alphanumerical designations
  • List the precautions to be taken when working with transistors and describe ways to test them
  • Understand how integrated circuits are constructed and the advantages they offer over conventional transistor circuits
  • Name the two types of circuit boards
  • State the purpose and function of modular circuitry
