Overview
The SMP4392TR is a JFET made by InterFET in a SOT-23-3 package with 3 pins.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:SMP4391, 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 C20515150).

Questions
Is there a KiCad symbol and footprint for the SMP4392TR?
Yes. The symbol is EasyEDA_Cloud:SMP4391 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 SMP4392TR?
SOT-23-3, with 3 pins. Its footprint is drawn on this page.
Where is the SMP4392TR datasheet?
InterFET publishes it: the Datasheet link on this page opens it.
Where can I order the SMP4392TR?
JLCPCB lists it as part C20515150, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMP4392TR?
Parts like it in the library: the SMP4391 by InterFET, the SMP4391TR by InterFET, the SMP4392 by InterFET and the MMBF4392 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
