Is there a KiCad symbol and footprint for the SMS240?
Yes. The symbol is Device:D_Schottky and the footprint Diode_SMD:D_MELF, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMS240?
DO-213AB, with 2 pins. Its footprint is drawn on this page.
Where is the SMS240 datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the SMS240?
JLCPCB lists it as part C3757458, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMS240?
Parts like it in the library: the BYM13-60-E3 by Vishay Intertechnology, the BYM13-40-E3 by Vishay Intertechnology, the SGL41-40-E3 by Vishay Intertechnology and the TMBYV10-60FILM by STMicroelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SMS240?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
