A 98.5 KB PDF titled with the 2SC3256 part number, placed in the schematic section yet most likely the device datasheet. In JIS numbering, 2SC means an NPN transistor. Since the name gives only the number, check the document for package, pin order and electrical limits. It helps when confirming a failed part by diode-mode testing, and when picking a replacement whose ratings meet or exceed the original.
