Is there a KiCad symbol and footprint for the SMAJ78A?
Yes. The symbol is Diode:SMAJ78A and the footprint Diode_SMD:D_SMA, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMAJ78A?
DO-214AC(SMA), with 2 pins. Its footprint is drawn on this page.
Where is the SMAJ78A datasheet?
GOODWORK publishes it: the Datasheet link on this page opens it.
Where can I order the SMAJ78A?
JLCPCB lists it as part C2943774, with 5,734 in stock; the sellers' links on this page open their listings.
What can replace the SMAJ78A?
Parts like it in the library: the SMAJ78A by BORN, the SMAJ78A/TR13 by Brightking, the SMAJ78CA/TR13 by Brightking and the SMAJ78A by DOWO. Check their datasheets: a part that fits the footprint may still differ in its ratings.
