Is there a KiCad symbol and footprint for the HER108?
Yes. The symbol is Device:D and the footprint EasyEDA_Cloud:DO-41_BD2.4-L4.7-P8.70-D0.9-RD, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HER108?
DO-41, with 2 pins. Its footprint is drawn on this page.
Where is the HER108 datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the HER108?
JLCPCB lists it as part C503813, with 19,639 in stock; the sellers' links on this page open their listings.
What can replace the HER108?
Parts like it in the library: the HER108G-K A0G by Taiwan Semiconductor. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the HER108?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
