Is there a KiCad symbol and footprint for the SB140?
Yes. The symbol is Diode:SB140 and the footprint Diode_THT:D_DO-41_SOD81_P10.16mm_Horizontal, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the SB140?
DO-41, with 2 pins. Its footprint is drawn on this page.
Where is the SB140 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the SB140?
JLCPCB lists it as part C896044, with 0 in stock; the sellers' links on this page open their listings.
What can replace the SB140?
Parts like it in the library: the 1N5819HW by Diodes Incorporated, the 1N5819 by KEXIN, the 1N5819W by Guangdong Hottech and the 1N5819W by Shandong Jingdao Microelectronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SB140?
26 boards in 23 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
