Overview
The BD681 is a darlington Transistor made by STMicroelectronics in a SOT-32-3 package with 3 pins. 100V 2.5V 200uA 40W 4A 5V 750 NPN SOT-32-3 Darlington Transistors ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:BD681, from EasyEDA) and its footprint (EasyEDA_Cloud:SOT-32_L7.6-W2.7-P2.29-R, from EasyEDA), ready for a KiCad board. 1,962 are in stock at JLCPCB (part C703688). 4 open-source boards in 4 repositories on GitHub use it.

Questions
Is there a KiCad symbol and footprint for the BD681?
Yes. The symbol is EasyEDA_Cloud:BD681 and the footprint EasyEDA_Cloud:SOT-32_L7.6-W2.7-P2.29-R, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BD681?
SOT-32-3, with 3 pins. Its footprint is drawn on this page.
Where is the BD681 datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the BD681?
JLCPCB lists it as part C703688, with 1,962 in stock; the sellers' links on this page open their listings.
What can replace the BD681?
Parts like it in the library: the BD678 by STMicroelectronics, the BD679A by STMicroelectronics, the BD677 by STMicroelectronics and the BD680 by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BD681?
4 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
