Is there a KiCad symbol and footprint for the STTH110A?
Yes. The symbol is Device:D and the footprint Diode_SMD:D_SMA, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the STTH110A?
SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.
Where is the STTH110A datasheet?
STMicroelectronics publishes it: the Datasheet link on this page opens it.
Where can I order the STTH110A?
JLCPCB lists it as part C99113, with 4,878 in stock; the sellers' links on this page open their listings.
What can replace the STTH110A?
Parts like it in the library: the US1M by MDD, the RS1M by hongjiacheng, the US1M by hongjiacheng and the RS1M by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the STTH110A?
2 boards in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
