Is there a KiCad symbol and footprint for the SMAJ51A?
Yes. The symbol is Diode:SMAJ51A 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 SMAJ51A?
DO-214AC(SMA), with 2 pins. Its footprint is drawn on this page.
Where is the SMAJ51A datasheet?
RUILON publishes it: the Datasheet link on this page opens it.
Where can I order the SMAJ51A?
JLCPCB lists it as part C27772, with 1,379 in stock; the sellers' links on this page open their listings.
What can replace the SMAJ51A?
Parts like it in the library: the SMAJ51A by hongjiacheng, the SMAJ51A by DOWO, the SMAJ51CA by Littelfuse and the SMAJ51A by Diodes Incorporated. Check their datasheets: a part that fits the footprint may still differ in its ratings.
