Is there a KiCad symbol and footprint for the MMBTA06W?
Yes. The symbol is Transistor_BJT:MMBTA06 and the footprint Package_TO_SOT_SMD:SOT-323_SC-70, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the MMBTA06W?
SC-70(SOT-323), with 3 pins. Its footprint is drawn on this page.
Where is the MMBTA06W datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the MMBTA06W?
JLCPCB lists it as part C92456, with 2,291 in stock; the sellers' links on this page open their listings.
What can replace the MMBTA06W?
Parts like it in the library: the SS8050 by Jiangsu Changjing Electronics Technology (CJ), the SS8050W-H by hongjiacheng, the MMBT4401W by onsemi and the BC817W(RANGE:160-400) by Jiangsu Changjing Electronics Technology (CJ). Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the MMBTA06W?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
