Questions

Is there a KiCad symbol and footprint for the B240A?

Yes. The symbol is Device:D_Schottky and the footprint Diode_SMD:D_SMA, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the B240A?

SMA, with 2 pins. Its footprint is drawn on this page.

Where is the B240A datasheet?

Diodes Incorporated publishes it: the Datasheet link on this page opens it.

Where can I order the B240A?

JLCPCB lists it as part C92506, with 136,800 in stock; the sellers' links on this page open their listings.

What can replace the B240A?

Parts like it in the library: the SS34 by MDD, the SS54 by MDD, the SS54 by hongjiacheng and the SS210 by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the B240A?

19 boards in 12 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
