Is there a KiCad symbol and footprint for the SMBJ28A?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SMB, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMBJ28A?
DO-214AA(SMB), with 2 pins. Its footprint is drawn on this page.
Where is the SMBJ28A datasheet?
GOODWORK publishes it: the Datasheet link on this page opens it.
Where can I order the SMBJ28A?
JLCPCB lists it as part C2848703, with 94,264 in stock; the sellers' links on this page open their listings.
What can replace the SMBJ28A?
Parts like it in the library: the SMBJ28CA by hongjiacheng, the SMBJ28A by 晶导微电子, the SMBJ28CA by 晶导微电子 and the SMBJ28A by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SMBJ28A?
26 boards in 24 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
