Is there a KiCad symbol and footprint for the SMCJ51CA?
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 SMCJ51CA?
DO-214AB(SMC), with 2 pins. Its footprint is drawn on this page.
Where is the SMCJ51CA datasheet?
RUILON publishes it: the Datasheet link on this page opens it.
Where can I order the SMCJ51CA?
JLCPCB lists it as part C10374, with 2,980 in stock; the sellers' links on this page open their listings.
What can replace the SMCJ51CA?
Parts like it in the library: the SMCJ51A by hongjiacheng, the SMCJ51CA by hongjiacheng, the SMCJ51A by MDD and the 5.0SMDJ51CA by BORN. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SMCJ51CA?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
