Test SCRs and Triacs with a Lab-Built Checker
Harman, Charles
Tech Directions, v69 n8 p22-25 Mar 2010
Students enrolled in advanced electronics courses and/or industrial electronics classes at the high school level and at technical colleges ultimately learn about solid-state switches such as the SCR (silicon controlled rectifier) and the triac. Both the SCR and the triac are in a family of four-layer devices called thyristors. They are both three-terminal devices and have enormous applications in the consumer field as well as in the industrial world. If tech students in a lab class inadvertently misconnected these components in an assignment, end-of-the-semester project, or senior project, they would know if their thyristors were still usable if they tested them with an SCR and triac checker. Using this handy SCR and triac checker, electronics students can effectively check SCRs and triacs for proper connections. This article describes how to build and use one. (Contains 4 figures.)
