Questions

Is there a KiCad symbol and footprint for the BCW251A?

Yes. The symbol is EasyEDA_Cloud:BCW251A and the footprint EasyEDA_Cloud:SMD-8_L9.7-W6.4-P2.54-LS9.7-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the BCW251A?

SMD-8P, with 8 pins. Its footprint is drawn on this page.

Where is the BCW251A datasheet?

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

Where can I order the BCW251A?

JLCPCB lists it as part C48533646, with 90 in stock; the sellers' links on this page open their listings.

What can replace the BCW251A?

Parts like it in the library: the LBB110STR by Littelfuse/IXYS, the LAA108STR by Littelfuse/IXYS, the LBA127LSTR by Littelfuse/IXYS and the LBB127STR by Littelfuse/IXYS. Check their datasheets: a part that fits the footprint may still differ in its ratings.
