Is there a KiCad symbol and footprint for the S40?
Yes. 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 S40?
TO-269AA, with 4 pins. Its footprint is drawn on this page.
Where is the S40 datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the S40?
JLCPCB lists it as part C3589895, with 0 in stock; the sellers' links on this page open their listings.
What can replace the S40?
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 S40?
3 boards in 2 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
