Listed under schematics, this 69.1 KB PDF covers the 1SS187 part number, with an uninformative trailing underscore. The 1SS series in Toshiba numbering is a family of small-signal switching diodes, so expect a single-device data sheet. Repair technicians rely on such sheets to decode SMD marking codes and confirm internal connections, which matters with multi-diode packages. They also use them to check current and voltage ratings before swapping in an equivalent. Any standard PDF reader will open the file.
