Is there a KiCad symbol and footprint for the QSD124?
Yes. the footprint EasyEDA_Cloud:CAP-TH_BD6.3-P2.50-D1.0-FD, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the QSD124?
插件, with 2 pins. Its footprint is drawn on this page.
Where is the QSD124 datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the QSD124?
JLCPCB lists it as part C897963, with 0 in stock; the sellers' links on this page open their listings.
What can replace the QSD124?
Parts like it in the library: the PT928-6C by Everlight Electronics, the BPW96C by Vishay Intertechnology, the SFH 313 FA-3/4 by OSRAM Opto Semicon and the PT334-6B-52 by Everlight Electronics. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the QSD124?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
