Transistor Amplifier Circuits Unit 6 – Transistor Specification Sheet
Exercise 2 – Using the Transistor Specification Sheet
EXERCISE OBJECTIVE
When you have completed this exercise, you will be able to locate maximum ratings, dc
characteristics, and operating parameters by using a typical transistor specification sheet. You
will verify your results by successfully completing all tasks.
DISCUSSION
- Manufacturer’s of transistors publish technical manuals which include the transistor
specification (data) sheets. - The manual usually contains an alphanumeric index indicating the page number where data
on a specific transistor is located. - Manuals, also, include information to help select the correct transistor for the application and
tables that compare specific transistor performance for general design or applications
groupings. - Specification sheets include sections for maximum ratings, electrical characteristics, and
characteristic curves. - Included in the data sheet are the transistor identification numbers, casing types, applications,
transistor configuration, and material. - Maximum ratings section provides operating parameters when a transistor is at its maximum
rating. - The Electrical Characteristics section consists of the following categories that provide
maximum and minimum parameter values required for circuit design.
Off characteristics
On characteristics
Small-signal characteristics
Switching Characteristics
