    So, collector and emitter are giving me lecture (both positions), and I have a question, is it common that these type of of transistors manage the signal of 12 volts that activates the relay in order to make a motor work? By the way I already tested the relay and it is ok, but no 12v signal, suspicious #1 NPN transistor!

    Hi, is this method for the transistor on the board connected to the battery or desoldered? Regards

    Does this test method apply to transistors installed on the PCB?

    • @electronictech785
      @electronictech785  4 місяці тому

      yes, but you also have to take into consideration of circuits that are in parallel to the transistor which can lead to misreading.

    Isn't it the current through the base of a BJT that matters, whereas MOSFETS its voltage?

    When testing an unknown BJT, the base pin (of both NPN and PNP) is easy enough to determine; but how do we distinguish which pin is the collector and which is the emitter?..

    • @mankeil4468
      @mankeil4468 4 роки тому

      Usually, just use the part number to search up the datasheet.
      If it doesn't have a part number you really can't even know if it's a transistor or something else (as the same kind of packages are used between a variety of components)

      one voltage drop should be slightly different from the other (google search).

    isn't one test is missing - Black Led on Base and Red on Collector and Multimeter should give you an "OL" Over limit reading

    Get an M tester they cost about $7 to $10. It can test transistors and lots of other things.

    make it so, you can read the multimeter to see what the diode setting is...for those that are not multi meter savy. please
