Is there a KiCad symbol and footprint for the SMFJ28A?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SOD-123F, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMFJ28A?
SOD-123F, with 2 pins. Its footprint is drawn on this page.
Where is the SMFJ28A datasheet?
BORN publishes it: the Datasheet link on this page opens it.
Where can I order the SMFJ28A?
JLCPCB lists it as part C5439963, with 3,866 in stock; the sellers' links on this page open their listings.
What can replace the SMFJ28A?
Parts like it in the library: the SMF28CA by hongjiacheng, the SMF28CA by GOODWORK, the SMF28CA by Shandong Jingdao Microelectronics and the SMF28CA by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SMFJ28A?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
