Overview
The BSS123 is an uncategorised made by HT in a SOT-23 package with 3 pins.
PCBKit's library has its KiCad symbol (Transistor_FET:BSS123, from KiCad's library) and its footprint (Package_TO_SOT_SMD:SOT-23, from KiCad's library), ready for a KiCad board. 2,984 are in stock at JLCPCB (part C23661579).

Is there a KiCad symbol and footprint for the BSS123?
Yes. The symbol is Transistor_FET:BSS123 and the footprint Package_TO_SOT_SMD:SOT-23, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BSS123?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the BSS123 datasheet?
HT publishes it: the Datasheet link on this page opens it.
Where can I order the BSS123?
JLCPCB lists it as part C23661579, with 2,984 in stock; the sellers' links on this page open their listings.
What can replace the BSS123?
Parts like it in the library: the CMN2922A by Cmos, the MMBD4148 by XCH, the MMBD4148SE by XCH and the BSS123 by Zhengxin. Check their datasheets: a part that fits the footprint may still differ in its ratings.
