    Can anyone tell the specifications to be checked for a transistor mainly for a npn?
    And also easily explain the limitations involved while using them?

    Your first concerns are current and voltage (collector to emitter). If the transistor isn't rated to well over whatever your circuit needs, the other specs don't matter.

    After those basics, your choices depend on your application. Things like current gain, frequency response and so on.

    Do you mean to troubleshoot a circuit or do you mean you want to test a transistor parameter or do you mean what should you check on a transistor data sheet?
