Questions

Is there a KiCad symbol and footprint for the STTH212U?

Yes. The symbol is Diode:STTH212U 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 STTH212U?

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

Where is the STTH212U datasheet?

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

Where can I order the STTH212U?

JLCPCB lists it as part C157394, with 552 in stock; the sellers' links on this page open their listings.

What can replace the STTH212U?

Parts like it in the library: the ES2DB by FOSAN, the STTH112U-FS by FUXINSEMI, the ES3JB by HY Elec and the UMW STTH112U by UMW. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the STTH212U?

4 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
