The symbol is Diode:SS14 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.
SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.
MDD publishes it: the Datasheet link on this page opens it.
JLCPCB lists it as part C2480, with 1,691,747 in stock; the sellers' links on this page open their listings.
Parts like it in the library: the SS34 by MDD, the SS54 by MDD, the SS54 by hongjiacheng and the SS210 by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
