The name of this 71.4 KB PDF is simply 1SS314, a part number from the 1SS small-signal diode series defined under Japanese JIS designation and common in Toshiba product lines. Although indexed as a schematic, it most likely describes one component. Repair use includes confirming the pinout and internal configuration, reading reverse voltage and current ratings, and identifying the part from its SMD marking. Compare the footprint and marking on the board with the sheet before choosing a replacement diode.
