Is there a KiCad symbol and footprint for the SMBJ48A?
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 SMBJ48A?
DO-214AA(SMB), with 2 pins. Its footprint is drawn on this page.
Where is the SMBJ48A datasheet?
RUILON publishes it: the Datasheet link on this page opens it.
Where can I order the SMBJ48A?
JLCPCB lists it as part C2987968, with 1,781 in stock; the sellers' links on this page open their listings.
What can replace the SMBJ48A?
Parts like it in the library: the SMBJ48CA by Brightking, the SMBJ48A by Shandong Jingdao Microelectronics, the SMBJ48A by HXY MOSFET and the SMBJ48A by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
