MMBT2222AT footprint and symbol numbering wrong

The pin numbering for the symbol of the MMBT2222AT do not match the pin numbering on the footprint. Pin 1 in the symbol library is emitter and pin 1 on the footprint is base. Pin 2 in the symbol library is base and pin 2 on the footprint is emitter. In other words the the base and emitter are reversed in the footprint and symbol library.


Welcome to the TechForum and Thank you for the feedback.

I will get this corrected as soon as possible and will let you know when the correction has been uploaded to GitHub.

Thanks again,

Could you check to make sure you are using the latest version of the library? We have made several corrections and updates to the library since the Beta version. The symbol for MMBT2222AT was one of the parts in the major update and appears this issue was fixed at that time. For the most up to date version visit:

Again, thank you for your feedback.
