Overview
The DO3139A is a MOSFET made by DOINGTER in a SOT-23 package with 3 pins. SOT-23 MOSFETs ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:DO3139A, from EasyEDA) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 2,740 are in stock at JLCPCB (part C54937223).

Questions
Is there a KiCad symbol and footprint for the DO3139A?
Yes. The symbol is EasyEDA_Cloud:DO3139A 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 DO3139A?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where can I order the DO3139A?
JLCPCB lists it as part C54937223, with 2,740 in stock; the sellers' links on this page open their listings.
What can replace the DO3139A?
Parts like it in the library: the HL2302B by hongjiacheng, the SQ2361CEES-T1_GE3 by Vishay Intertechnology, the SI2318 by GOODWORK and the HL3401 by HL. Check their datasheets: a part that fits the footprint may still differ in its ratings.
