Check that JFET! Easy-to-Build Tester Makes It Simple
Harman, Charles
Tech Directions, v68 n3 p24-26 Oct 2008
This article describes an activity that will allow students to learn how to make a junction field effect transistor (JFET) checker. Most electronics students do not have the experience or knowledge that it takes to recognize whether a JFET is operating normally, and both instructors and students will find having the means to check the operation of a JFET at the proto-board stage helpful. With the described JFET checker, a person can remove the component in question from the proto-board, insert the component into the JFET checker, push the press-to-test button, and observe the JFET' checkers light-emitting diode (LED).
