Overview
The SMPJ109TR is a JFET made by InterFET in a SOT-23-3 package with 3 pins. SOT-23-3 JFETs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:IFN160BST3TR, 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 C20514288).

Is there a KiCad symbol and footprint for the SMPJ109TR?
Yes. The symbol is EasyEDA_Cloud:IFN160BST3TR 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 SMPJ109TR?
SOT-23-3, with 3 pins. Its footprint is drawn on this page.
Where is the SMPJ109TR datasheet?
InterFET publishes it: the Datasheet link on this page opens it.
Where can I order the SMPJ109TR?
JLCPCB lists it as part C20514288, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMPJ109TR?
Parts like it in the library: the MMBFJ110 by onsemi, the IF140ST3 by InterFET, the IF140ST3TR by InterFET and the SMP4391 by InterFET. Check their datasheets: a part that fits the footprint may still differ in its ratings.
