Is there a KiCad symbol and footprint for the GH39FKSW?
Yes. The symbol is EasyEDA_Cloud:TMP236AQDBZTQ1 and the footprint Package_TO_SOT_SMD:SOT-23-3, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the GH39FKSW?
SOT-23-3L, with 3 pins. Its footprint is drawn on this page.
Where is the GH39FKSW datasheet?
HiTrend Tech publishes it: the Datasheet link on this page opens it.
Where can I order the GH39FKSW?
JLCPCB lists it as part C266230, with 2,151 in stock; the sellers' links on this page open their listings.
What can replace the GH39FKSW?
Parts like it in the library: the HAL49ESO by Hallwee, the CC6103EST by Cross chip, the HAL9303RSO by Hallwee and the HAL403SO by Hallwee. Check their datasheets: a part that fits the footprint may still differ in its ratings.
