Questions
Is there a KiCad symbol and footprint for the BD139?
Yes. The symbol is Transistor_BJT:BD139 and the footprint Package_TO_SOT_THT:TO-126-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BD139?
TO-225-3, with 3 pins. Its footprint is drawn on this page.
Where is the BD139 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the BD139?
JLCPCB lists it as part C233736, with 386 in stock; the sellers' links on this page open their listings.
What can replace the BD139?
Parts like it in the library: the BD139 by STMicroelectronics, the BD139-16 by STMicroelectronics, the BD237 by Jiangsu Changjing Electronics Technology (CJ) and the BD441 by onsemi. Check their datasheets: a part that fits the footprint may still differ in its ratings.
