Is there a KiCad symbol and footprint for the SMF22A?
Yes. The symbol is Diode:SMF22A and the footprint Diode_SMD:D_SMF, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMF22A?
SOD-123FL, with 2 pins. Its footprint is drawn on this page.
Where is the SMF22A datasheet?
GOODWORK publishes it: the Datasheet link on this page opens it.
Where can I order the SMF22A?
JLCPCB lists it as part C2943862, with 102,464 in stock; the sellers' links on this page open their listings.
What can replace the SMF22A?
Parts like it in the library: the SMF22A-TP by Micro Commercial Components, the SMF22A by FOSAN, the SMF22A by JSMSEMI and the SMF22A by Shandong Jingdao Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SMF22A?
5 boards in 4 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
