Is there a KiCad symbol and footprint for the DMP2045U?
Yes. The symbol is Transistors:P-MOSFET-D 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 DMP2045U?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the DMP2045U datasheet?
TECH PUBLIC publishes it: the Datasheet link on this page opens it.
Where can I order the DMP2045U?
JLCPCB lists it as part C2959855, with 1,371 in stock; the sellers' links on this page open their listings.
What can replace the DMP2045U?
Parts like it in the library: the AP40P05 by ALLPOWER, the 5N10-MS by MSKSEMI, the IRLML6402TRPBF by TECH PUBLIC and the SI2318CDS by Vishay Intertechnology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the DMP2045U?
13 boards in 12 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
