Is there a KiCad symbol and footprint for the SMCJ18A?
Yes. The symbol is Device:D_TVS and the footprint Diode_SMD:D_SMC, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SMCJ18A?
DO-214AB, with 2 pins. Its footprint is drawn on this page.
Where is the SMCJ18A datasheet?
Me-TECH publishes it: the Datasheet link on this page opens it.
Where can I order the SMCJ18A?
JLCPCB lists it as part C501771, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SMCJ18A?
Parts like it in the library: the SMCJ18CA by Shandong Jingdao Microelectronics, the SMCJ18A by BORN, the SMCJ18CA by hongjiacheng and the 5.0SMDJ18CA by BORN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
