Simple Transistor Tester
This is a simple circuit but we hope it will help you a lot and save your valuable time. You do not have to use millimeter to test a transistor if you build this circuit. You can have a 9 volts battery to operate the circuit. No matter if the transistor is NPN or PNP, if the transistor is shorted then no any LED should light. If the transistor is open Both the LED should light.
Now remember when you test a good PNP transistor then LED2 should light.
For NPN good transistor only LED1 should light.
Try to make the circuit on a PCB and put in a small box for its safety. Find a three pin socket and mounted it on the box. When you fix everything, only visible parts from the out side of the box should be the switch and three pins of the socket to test a transistor.
