Is there a KiCad symbol and footprint for the MBR0540T1G?
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 MBR0540T1G?
SOD-123, with 2 pins. Its footprint is drawn on this page.
Where is the MBR0540T1G datasheet?
GOODWORK publishes it: the Datasheet link on this page opens it.
Where can I order the MBR0540T1G?
JLCPCB lists it as part C42385147, with 9,118 in stock; the sellers' links on this page open their listings.
What can replace the MBR0540T1G?
Parts like it in the library: the B5819W by MDD, the B5819W by hongjiacheng, the B5819W by HXY MOSFET and the B5819W SL by SEP. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the MBR0540T1G?
14 boards in 11 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
