Questions

Is there a KiCad symbol and footprint for the STPS2L40U?

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 STPS2L40U?

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

Where is the STPS2L40U datasheet?

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

Where can I order the STPS2L40U?

JLCPCB lists it as part C169095, with 4,494 in stock; the sellers' links on this page open their listings.

What can replace the STPS2L40U?

Parts like it in the library: the SS510B by hongjiacheng, the SS54B by hongjiacheng, the SS56B by hongjiacheng and the SS34 by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the STPS2L40U?

4 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
