Overview
The BDW94C is a darlington Transistor made by STMicroelectronics in a TO-220 package with 3 pins. 100V 100uA 12A 3V 4V 750 80W PNP TO-220 Darlington Transistors ROHS.
PCBKit's library has its KiCad symbol (Transistor_BJT:BDW94C, from KiCad's library) and its footprint (Package_TO_SOT_THT:TO-220-3_Vertical, from KiCad's library), ready for a KiCad board. 1,080 are in stock at JLCPCB (part C495217). 1 open-source board in 1 repository on GitHub use it.

Is there a KiCad symbol and footprint for the BDW94C?
Yes. The symbol is Transistor_BJT:BDW94C and the footprint Package_TO_SOT_THT:TO-220-3_Vertical, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BDW94C?
TO-220, with 3 pins. Its footprint is drawn on this page.
Where is the BDW94C datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the BDW94C?
JLCPCB lists it as part C495217, with 1,080 in stock; the sellers' links on this page open their listings.
What can replace the BDW94C?
Parts like it in the library: the BDW93C by STMicroelectronics, the BDW93C by SPTECH, the TIP127 by Slkor and the TIP112 PBFREE by Central Semicon. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the BDW94C?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
