Questions
Is there a KiCad symbol and footprint for the UMH3N?
Yes. The symbol is Transistor_BJT:UMH3N and the footprint Package_TO_SOT_SMD:SOT-363_SC-70-6, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the UMH3N?
SOT-363, with 6 pins. Its footprint is drawn on this page.
Where is the UMH3N datasheet?
Jiangsu Changjing Electronics Technology (CJ) publishes it: the Datasheet link on this page opens it.
Where can I order the UMH3N?
JLCPCB lists it as part C62892, with 20,843 in stock; the sellers' links on this page open their listings.
What can replace the UMH3N?
Parts like it in the library: the MUN5211DW1 by onsemi, the PUMD9,115 by Nexperia, the SMUN5131DW1 by onsemi and the LMUN5335DW1T1G by Leshan Radio (LRC). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the UMH3N?
130 boards in 94 repositories on GitHub; the most starred are listed on this page, with their KiCad files.
