2N2222 vs PN2222 vs P2N2222: reversed pinouts engineers must re-Google every few years
johnowhitaker · x · 2026-10-12
johnowhitaker shares the perpetually confusing transistor pinout chart: the 2N2222A/PN2222A and P2N2222A have opposite E/B/C pin orders, forcing engineers to re-check datasheets every few years. He jokes it's a "never-ending humiliation ritual" he'll still be doing post-singularity, floating in space with a baggie of misc transistors.
