Is there a KiCad symbol and footprint for the SL3401A?
Yes. The symbol is Pinmap_Generic:Q_PMOS_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 SL3401A?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the SL3401A datasheet?
Slkor publishes it: the Datasheet link on this page opens it.
Where can I order the SL3401A?
JLCPCB lists it as part C350311, with 2,244 in stock; the sellers' links on this page open their listings.
What can replace the SL3401A?
Parts like it in the library: the AO3400A by Alpha & Omega Semiconductor, the AO3400A by UMW, the AO3401A by UMW and the AO3400 by Guangdong Hottech. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the SL3401A?
