Transistor is an semiconductor device which is used to amplify or Regulate the path of the electrical signals.Transistor have a wide variety of applications in various fields. Transistor have basically three Pins that are: collector, Base, Emitter. If you are using Transistor in your Project as a Amplifier or Switch. You need to Know all the three pins of the Transistor before start working with it. I will be using a Multi-meter to test the pins of the Transistor.
To identify these three Pins, First you can identify the BASE which is very easy to identify. Base is generally the middle Pin of any Transistor. The next Step is to Identify the other two Pins of the Transistor. For this take up the:
- Take Multimeter
- Set the Pointer to HREF
- Insert the Transistor into NPN or PNP block
- Insert its three legs into ECB or BCE.
If you get any Reading then you have correctly Identified the Transistor.
If not, Try Inserting the Transistor into the other configuration of BCE.
If you still Didn’t get Reading try inserting it into the the ECB of PNP (if you tried on NPN first).
Now you will surely get the Reading if your Transistor is OK!
These are are the correct Pins of Transistor . Where you get Reading you just Stop.
You can check out my other Post if you don’t have Multimeter and stuck at finding Pins of Transistor.
