    Please suggest me the use of transistors like PDTA124EU (two resistors
    inside it, one between the emitter and base and one at the base) and
    MOSFETs like NTJS3151P.

    I used them in my project where an MCU was driving the transistor
    directly, with the transistor acting like a switch. The two resistors
    turn the digital signal into a correctly biased/limited/etc signal, so
    as to not cause problems for the MCU. Otherwise, I'd have to at least
    put a limiter resistor between the MCU and a standard transistor.
