Is there a KiCad symbol and footprint for the CJ3420?
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 CJ3420?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the CJ3420 datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the CJ3420?
JLCPCB lists it as part C81780, with 8,684 in stock; the sellers' links on this page open their listings.
What can replace the CJ3420?
Parts like it in the library: the IRLML2502TRPBF by TECH PUBLIC, the AO3416 by Alpha & Omega Semiconductor, the PMV16XNR by Nexperia and the PMV20XNER by Nexperia. Check their datasheets: a part that fits the footprint may still differ in its ratings.
