Is there a KiCad symbol and footprint for the SL54B?
Yes. The symbol is Device:D_Schottky and the footprint Diode_SMD:D_SMB, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SL54B?
SMB(DO-214AA), with 2 pins. Its footprint is drawn on this page.
Where is the SL54B datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the SL54B?
JLCPCB lists it as part C113940, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SL54B?
Parts like it in the library: the SS510B by hongjiacheng, the SS54B by hongjiacheng, the SS56B by hongjiacheng and the SS56B by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SL54B?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
