MBRA340

Q: Is there a KiCad symbol and footprint for the MBRA340?

Yes. The symbol is Diode:MBRA340 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.

Q: What package is the MBRA340?

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

Q: Where is the MBRA340 datasheet?

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

Q: Where can I order the MBRA340?

JLCPCB lists it as part C26178, with 126,374 in stock; the sellers' links on this page open their listings.

Q: What can replace the MBRA340?

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

Q: Which open-source boards use the MBRA340?

16 boards in 14 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
