Is there a KiCad symbol and footprint for the S250?
Yes. The symbol is EasyEDA_Cloud:MB10S_C211753 and the footprint Package_TO_SOT_SMD:TO-269AA, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the S250?
TO-269AA, with 4 pins. Its footprint is drawn on this page.
Where is the S250 datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the S250?
JLCPCB lists it as part C212803, with 0 in stock; the sellers' links on this page open their listings.
What can replace the S250?
Parts like it in the library: the MB6S by Guangdong Hottech, the MB6S by MDD, the MB6S by MDD and the MB6S by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the S250?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
