Is there a KiCad symbol and footprint for the MMBZ27VAL?
Yes. The symbol is Diode:MMBZxx 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 MMBZ27VAL?
SOT-23, with 3 pins. Its footprint is drawn on this page.
Where is the MMBZ27VAL datasheet?
onsemi publishes it: the Datasheet link on this page opens it.
Where can I order the MMBZ27VAL?
JLCPCB lists it as part C41376, with 18,681 in stock; the sellers' links on this page open their listings.
What can replace the MMBZ27VAL?
Parts like it in the library: the MMBZ27VCL,215 by Nexperia, the MMBZ27VAL,235 by Nexperia, the MMBZ27VCL by onsemi and the MMBZ27VAL by DOWO. Check their datasheets: a part that fits the footprint may still differ in its ratings.
Which open-source boards use the MMBZ27VAL?
1 board in 1 repository on GitHub; the most starred are listed on this page, with their KiCad files.
