Is there a KiCad symbol and footprint for the CEP3120?
Yes. The symbol is Pinmap_Generic:Q_NMOS_1G_2D_3S and the footprint EasyEDA_Cloud:TO-220-3_L10.0-W4.5-P2.54-L-1, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the CEP3120?
TO-220, with 3 pins. Its footprint is drawn on this page.
Where is the CEP3120 datasheet?
CET publishes it: the Datasheet link on this page opens it.
Where can I order the CEP3120?
JLCPCB lists it as part C154168, with 0 in stock; the sellers' links on this page open their listings.
What can replace the CEP3120?
Parts like it in the library: the IPP030N10N3GXKSA1 by Infineon Technologies, the STP140NF75 by STMicroelectronics, the FDP090N10 by onsemi and the IPP111N15N3GXKSA1 by Infineon Technologies. Check their datasheets: a part that fits the footprint may still differ in its ratings.
