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.
Special Transistors?

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…

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.
