Transistor Tester Circuit Diagram. The figure shows the circuit diagram of transistor tester. You just know only position legs of a transistor.
We have structured this article into two circuits. The voltage source is a 6v power supply which is 230v ac to 6v step down transformer. This is a very simple circuit which can be used for testing of scrs as well as triacs.
The transistor is provided with a led to drive.
Then place the probe and press s1 see the led indicator good or bad of the transistor easily. In this circuit the timer function is to work as a square wave generator and to provide clock for the transistor. As you know there are three terminals of a transistor base emitter and collector. You just know only position legs of a transistor.
