A 67.4 KB PDF for the 1SS385, classed as a schematic but most likely the component datasheet, given the Japanese 1SS small-signal diode designation. The filename includes only the number and an underscore, with no brand, model or board revision. A suffixed 1SS385F version sits separately in the index, so check which one matches the marking on your board. The sheet gives ratings, polarity and the package drawing needed to test or replace the diode. Opens in any standard PDF viewer.
