Questions

Is there a KiCad symbol and footprint for the MBR0540?

Yes. The symbol is Diode:MBR0540 and the footprint Diode_SMD:D_SOD-123, both drawn on this page. PCBKit places them on a board for you when you design with it.

What package is the MBR0540?

SOD-123, with 2 pins. Its footprint is drawn on this page.

Where is the MBR0540 datasheet?

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

Where can I order the MBR0540?

JLCPCB lists it as part C236080, with 11,346 in stock; the sellers' links on this page open their listings.

What can replace the MBR0540?

Parts like it in the library: the B5819W by GOODWORK, the B5819W SL by Jiangsu Changjing Electronics Technology (CJ), the B5819W by MDD and the MBR0540 by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
