You’ve probably encountered this before — you have a circuit board that is poorly documented, and want to know the part number of a tiny SMD chip. Retro computer enthusiast [JohnK] rece… ...

These SMD diodes come in industry-standard packages, but do you think there’s an industry-standard way of marking the cathode? Nope, not by a long shot.

The sealed SMD laser source is currently available for the 655nm wavelength and delivers 10mW of laser power at an operating current of 25mA. “ADL-65074zl is the first laser diode that combines the ...
