Is there a KiCad symbol and footprint for the S1G?
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 S1G?
SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.
Where is the S1G datasheet?
TWGMC publishes it: the Datasheet link on this page opens it.
Where can I order the S1G?
JLCPCB lists it as part C727098, with 29,643 in stock; the sellers' links on this page open their listings.
What can replace the S1G?
Parts like it in the library: the M7 by MDD, the M7 by hongjiacheng, the M7 by MSKSEMI and the M7 by Yangzhou Yangjie Electronic Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the S1G?
15 boards in 14 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
