Small 70.2 KB PDF for the 1SS396 component, placed in the schematic category. Given the 1SS numbering, the Japanese series for small-signal diodes, it is most likely a manufacturer datasheet rather than a board diagram. No model, brand or board number is stated in the name. It helps when a part needs identifying from its tiny marking code, or when you want ratings and the package outline to choose a compatible replacement. Read it in any PDF program and verify polarity before fitting a new diode.
