ROHM-issued datasheet for the 1N4148 switching diode, saved as a 219 KB PDF and indexed under schematics. Because the vendor is named, the package drawings, marking and characteristic curves reflect ROHM production specifically. Open it in any PDF reader to check forward voltage versus current graphs, reverse recovery time and soldering conditions. It is handy when matching a replacement for a small-signal diode on a board, and different makers may list slightly different limits, so compare when sourcing an alternative.
