Is there a KiCad symbol and footprint for the MDD2300?
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 MDD2300?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the MDD2300 datasheet?
MDD publishes it: the Datasheet link on this page opens it.
Where can I order the MDD2300?
JLCPCB lists it as part C427387, with 4,168 in stock; the sellers' links on this page open their listings.
What can replace the MDD2300?
Parts like it in the library: the SI2333-HXY by HXY MOSFET, the SQ2318AES-T1_BE3 by Vishay Intertechnology, the 2320A by HL and the SI2369DS by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the MDD2300?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
