Is there a KiCad symbol and footprint for the US1Q-TP?
Yes. The symbol is Device:D 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 US1Q-TP?
SMA(DO-214AC), with 2 pins. Its footprint is drawn on this page.
Where is the US1Q-TP datasheet?
Micro Commercial Components publishes it: the Datasheet link on this page opens it.
Where can I order the US1Q-TP?
JLCPCB lists it as part C914452, with 12,508 in stock; the sellers' links on this page open their listings.
What can replace the US1Q-TP?
Parts like it in the library: the STTH112A by STMicroelectronics, the STTH112A-FS by FUXINSEMI, the H1HV12 by amsem and the FR2WSMA by DIOTEC. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the US1Q-TP?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
