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?
SMC(DO-214AB), with 2 pins. Its footprint is drawn on this page.
Where is the SMCJ18A datasheet?
BORN publishes it: the Datasheet link on this page opens it.
Where can I order the SMCJ18A?
JLCPCB lists it as part C151906, with 6,876 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 SMCJ18CA by hongjiacheng, the 5.0SMDJ18CA by BORN and the SMCJ18CA by BORN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SMCJ18A?
7 boards in 7 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
