Overview
The SMP4220TR is a JFET made by InterFET in a SOT-23 package with 3 pins.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:SMP4220TR, from EasyEDA) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C20514713).

Questions
Is there a KiCad symbol and footprint for the SMP4220TR?
Yes. The symbol is EasyEDA_Cloud:SMP4220TR and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMP4220TR?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SMP4220TR datasheet?
InterFET publishes it: the Datasheet link on this page opens it.
Where can I order the SMP4220TR?
JLCPCB lists it as part C20514713, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMP4220TR?
Parts like it in the library: the MMBFJ111 by onsemi, the MMBF4093 by onsemi, the CMPF4391 TR TIN/LEAD by Central Semicon and the CMPF4392 TR PBFREE by Central Semicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
