iam working on a pcb project. How to find the equivalent SMD component for THT components like transistor,diode,FET? I got many part numbers while searching, so confused about SMD component selection.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
You first need to check the data sheet for the devices and see if they are offered in SMT packages, many are available in different packages.
If not, you need to identify the key parameters that were used to chose the parts in the first place. If you did not design the circuit, then ask whomever did to pick the right SMT parts.
If you end up having to chose the parts yourself, visit one of the general suppliers like Digikey, or Mouser and use their nice parametric search part listings to find parts that meet or exceed the required paramaters. Do not forget to check the prices/availability too.
