Is there a KiCad symbol and footprint for the BD680?
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 BD680?
TO-126, with 5 pins. Its footprint is drawn on this page.
Where is the BD680 datasheet?
DDF publishes it: the Datasheet link on this page opens it.
Where can I order the BD680?
JLCPCB lists it as part C50229438, with 495 in stock; the sellers' links on this page open their listings.
What can replace the BD680?
Parts like it in the library: the BD678 by DDF, the BD679 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 BD680?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
