Overview
The SMP4117A is a JFET made by InterFET in a SOT-23-3 package with 3 pins.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:SMP4117A, from EasyEDA) and its footprint (Package_TO_SOT_SMD:SOT-23-3, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C20516314).

Questions
Is there a KiCad symbol and footprint for the SMP4117A?
Yes. The symbol is EasyEDA_Cloud:SMP4117A and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMP4117A?
SOT-23-3, with 3 pins. Its footprint is drawn on this page.
Where is the SMP4117A datasheet?
InterFET publishes it: the Datasheet link on this page opens it.
Where can I order the SMP4117A?
JLCPCB lists it as part C20516314, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMP4117A?
Parts like it in the library: the MMBFJ112 by onsemi, the MMBFJ201 by onsemi, the MMBFJ110 by onsemi and the IF1320ST3TR by InterFET. Check their datasheets: a part that fits the footprint may still differ in its ratings.
