📄 Unlocking the Mystery: The Ultimate Guide to Active SMD Semiconductor Marking Codes
Like many of you, I struggle with reading those tiny 2-3 letter codes on SMD transistors and diodes. I got tired of searching through 10 different datasheets every time I see a "W04" or "R1".

I’ve put together a comprehensive resource focusing on (Transistors, Diodes, LEDs, Voltage Regulators, and ICs).
Hope this saves you some time. Let me know if you see any major brands missing.
