Questions

Is there a KiCad symbol and footprint for the B290?

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 B290?

SMB(DO-214AA), with 2 pins. Its footprint is drawn on this page.

Where is the B290 datasheet?

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

Where can I order the B290?

JLCPCB lists it as part C134446, with 741 in stock; the sellers' links on this page open their listings.

What can replace the B290?

Parts like it in the library: the SS510B by hongjiacheng, the SS310B by MDD, the SS520B by Shandong Jingdao Microelectronics and the SS310 by ElecSuper. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the B290?

1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
