Questions
Is there a KiCad symbol and footprint for the BSS138W?
Yes. The symbol is Transistor_FET:BSS138 and the footprint Package_TO_SOT_SMD:SOT-323_SC-70, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the BSS138W?
SOT-323, with 3 pins. Its footprint is drawn on this page.
Where is the BSS138W datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the BSS138W?
JLCPCB lists it as part C504052, with 33,048 in stock; the sellers' links on this page open their listings.
What can replace the BSS138W?
Parts like it in the library: the BSS138W by hongjiacheng, the 2N7002W by onsemi, the L2N7002SWT1G by Leshan Radio (LRC) and the 2N7002W-7-F-ES by ElecSuper. Check their datasheets: a part that fits the footprint may still differ in its ratings.
