Questions

Is there a KiCad symbol and footprint for the SM340B?

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 SM340B?

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

Where is the SM340B datasheet?

Leshan Radio (LRC) publishes it: the Datasheet link on this page opens it.

Where can I order the SM340B?
