Questions

Is there a KiCad symbol and footprint for the SS34?

Yes. The symbol is Diode:SS34 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 SS34?

SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.

Where is the SS34 datasheet?

MDD publishes it: the Datasheet link on this page opens it.

Where can I order the SS34?

JLCPCB lists it as part C8678, with 3,077,398 in stock; the sellers' links on this page open their listings.

What can replace the SS34?

Parts like it in the library: the SS54 by MDD, the SS54 by hongjiacheng, the SS56 by hongjiacheng and the SS34 by hongjiacheng. Check their datasheets: a part that fits the footprint may still differ in its ratings.

Which open-source boards use the SS34?

1,239 boards in 966 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
