Is there a KiCad symbol and footprint for the ST20100S?
Yes. The symbol is EasyEDA_Cloud:PMEG4010CPASX and the footprint EasyEDA_Cloud:TO-277B-3_L5.4-W4.0-P1.84-LS6.5-TR, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the ST20100S?
TO-277B-3, with 3 pins. Its footprint is drawn on this page.
Where is the ST20100S datasheet?
SMC publishes it: the Datasheet link on this page opens it.
Where can I order the ST20100S?
JLCPCB lists it as part C492899, with 4,600 in stock; the sellers' links on this page open their listings.
What can replace the ST20100S?
Parts like it in the library: the FSV20150V by onsemi, the ST20150L by Jiangsu Changjing Electronics Technology (CJ) and the ST20100L by FUXINSEMI. Check their datasheets: a part that fits the footprint may still differ in its ratings.
