Questions
Is there a KiCad symbol and footprint for the SI2309S?
Yes. The symbol is Pinmap_Generic:Q_PMOS_1G_2S_3D 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 SI2309S?
SOT-23-3L, with 3 pins. Its footprint is drawn on this page.
Where is the SI2309S datasheet?
BORN publishes it: the Datasheet link on this page opens it.
Where can I order the SI2309S?
JLCPCB lists it as part C2997263, with 11,592 in stock; the sellers' links on this page open their listings.
What can replace the SI2309S?
Parts like it in the library: the ST3422A by STANSON Tech., the AP5N10S by ALLPOWER, the AP2310 by ALLPOWER and the AO3422-HXY by HXY MOSFET. Check their datasheets: a part that fits the footprint may still differ in its ratings.
