Is there a KiCad symbol and footprint for the SMAJ30CA?
Yes. The symbol is Diode:SMAJ30CA 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.
What package is the SMAJ30CA?
DO-214AC(SMA), with 2 pins. Its footprint is drawn on this page.
Where is the SMAJ30CA datasheet?
GOODWORK publishes it: the Datasheet link on this page opens it.
Where can I order the SMAJ30CA?
JLCPCB lists it as part C908828, with 317,762 in stock; the sellers' links on this page open their listings.
What can replace the SMAJ30CA?
Parts like it in the library: the SMAJ30A by GOODWORK, the SMAJ30CA by MDD, the SMAJ30CA by Diodes Incorporated and the SMAJ30A by MDD. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SMAJ30CA?
20 boards in 19 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
