Questions

Is there a KiCad symbol and footprint for the MBRS340?

Yes. The symbol is Diode:MBRS340 and the footprint Diode_SMD:D_SMC, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MBRS340?

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

Where is the MBRS340 datasheet?

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

Where can I order the MBRS340?

JLCPCB lists it as part C40326, with 22,206 in stock; the sellers' links on this page open their listings.

What can replace the MBRS340?

Parts like it in the library: the B560C by Diodes Incorporated, the SS10100 by ShunYe, the SS520C by TDD and the SS56 by ShunYe. Check their datasheets: a part that fits the footprint may still differ in its ratings.
