Questions
Is there a KiCad symbol and footprint for the KY3404?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2S_3D 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 KY3404?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the KY3404 datasheet?
KY publishes it: the Datasheet link on this page opens it.
Where can I order the KY3404?
JLCPCB lists it as part C3029294, with 2,230 in stock; the sellers' links on this page open their listings.
What can replace the KY3404?
Parts like it in the library: the MDD3400 by MDD, the AO3400A-MS by MSKSEMI, the SQ2318AES-T1_BE3 by Vishay Intertechnology and the SI2369DS by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
