The draft covers all seven sections, but the stored manufacturer datasheet appears to cover A-suffix parts rather than the exact non-A part. I’m checking the circuit examples and keeping that verification gap explicit.

Created the 2N2222 Application and Usage Guide in the project files, covering all seven requested sections, checked base-drive calculations, alternatives, and source links.

Verification gap: the exact Solid State Inc. non-A datasheet was unavailable; affected ratings, pin orientation, and sourcing details are explicitly marked unverified. Before production use, obtain that datasheet and confirm the physical lead mapping.
