Is there a KiCad symbol and footprint for the SMF17A?
Yes. The symbol is Diode:SMF17A 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 SMF17A?
SOD-123FL, with 2 pins. Its footprint is drawn on this page.
Where is the SMF17A datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the SMF17A?
JLCPCB lists it as part C2994190, with 14,917 in stock; the sellers' links on this page open their listings.
What can replace the SMF17A?
Parts like it in the library: the SMF16A by Littelfuse, the SMF17A by FOSAN, the SMF17A by JSMSEMI and the SMF17A by DIOTEC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SMF17A?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
