Note specifically, his hints on how to distinguish one terminal from the other. But same principle applies to most all of them. Specifically about the kind of triacs used in microwave ovens. The guy has some hints about testing triacs. Thanks.Well, I'm not sure just how deeply yah really want to dig into the inner workings of semi-conductors.īut maybe some of the following links might be helpful. I am looking for some good lit on what they are and how to test them that I can give out. I am giving an in house training next week and I would like to include triacs in the class. To test triacs i use 2 rib relays and watch the lights. Of course, the first triac you test should be the one you just removed. For the test triac with no heat sink I'd use a 25w incand. These dimmers can handle 600w because the triac is on a heat sink. The triac under test, fastened with 3 clip leads, substitutes for the internal triac (which you removed). Get the part number off the triac inside to get a data sheet from the Web and figure out which is A1, A2 and G (or just figure it out from the wiring) and then use this dimmer as a test bed.
You could probably make your own tester with a 24vac xformer, a 24v incand. With a 9v battery through a 390 ohm resistor into the gate it should look like a low impedance in both directions. With no gate voltage applied the thing should look like a high impedance in both directions. If you have any problems with the registration process or your account login, please contact support.
