Questions

Is there a KiCad symbol and footprint for the BD679?

Yes. the footprint EasyEDA_Cloud:TO-126-3_L7.6-W2.7-P2.30-L, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BD679?

TO-126, with 5 pins. Its footprint is drawn on this page.

Where is the BD679 datasheet?

DDF publishes it: the Datasheet link on this page opens it.

Where can I order the BD679?

JLCPCB lists it as part C50229439, with 0 in stock; the sellers' links on this page open their listings.

What can replace the BD679?

Parts like it in the library: the BD678 by DDF, the BD680 by DDF and the BD681 by luJing. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the BD679?

6 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
