Overview
The BSS139 is a MOSFET made by GOODWORK in a SOT-23 package with 3 pins.
PCBKit's library has its KiCad symbol (Transistors:N-SIPMOS-D DM 1G 2S 3D, from CERN's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 2,336 are in stock at JLCPCB (part C46061575).

Questions
Is there a KiCad symbol and footprint for the BSS139?
Yes. The symbol is Transistors:N-SIPMOS-D DM 1G 2S 3D 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 BSS139?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BSS139 datasheet?
GOODWORK publishes it: the Datasheet link on this page opens it.
Where can I order the BSS139?
JLCPCB lists it as part C46061575, with 2,336 in stock; the sellers' links on this page open their listings.
What can replace the BSS139?
Parts like it in the library: the 2N7002K by hongjiacheng, the BSS138 by hongjiacheng, the 2N7002K by Diodes Incorporated and the BSS138P by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
