Is there a KiCad symbol and footprint for the S1KB?
Yes. The symbol is Device:D 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 S1KB?
SMB(DO-214AA), with 2 pins. Its footprint is drawn on this page.
Where is the S1KB datasheet?
Diodes Incorporated publishes it: the Datasheet link on this page opens it.
Where can I order the S1KB?
JLCPCB lists it as part C460934, with 1,420 in stock; the sellers' links on this page open their listings.
What can replace the S1KB?
Parts like it in the library: the S3MB by hongjiacheng, the S3MB by MDD, the S2M by MDD and the S5MB by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the S1KB?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
