Overview
The USL1G is a switching Diode made by DIOTEC in a SOD-123F(SMF) package with 2 pins.
PCBKit's library has its KiCad symbol (Device:D, from KiCad's library) and its footprint (Diode_SMD:D_SOD-123F, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C17312722). 1 open-source board in 1 repository on GitHub use it.

Is there a KiCad symbol and footprint for the USL1G?
Yes. The symbol is Device:D and the footprint Diode_SMD:D_SOD-123F, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the USL1G?
SOD-123F(SMF), with 2 pins. Its footprint is drawn on this page.
Where is the USL1G datasheet?
DIOTEC publishes it: the Datasheet link on this page opens it.
Where can I order the USL1G?
JLCPCB lists it as part C17312722, with 0 in stock; the sellers' links on this page open their listings.
What can replace the USL1G?
Parts like it in the library: the FSM14PL-TP by Micro Commercial Components, the RS1MSWFM by Diodes Incorporated, the RS1MSWFMQ by Diodes Incorporated and the FSM155PL-TP by Micro Commercial Components. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the USL1G?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
