Indexed as a schematic, this 41.7 KB PDF carries the part number 2SC1360, an NPN transistor according to Japanese JIS numbering, which points to a datasheet for a single discrete component. The _E tag probably denotes English text. Datasheets of this kind list pin assignment, case outline, breakdown voltages, collector current and gain groups. Before soldering in a replacement, compare those ratings with the original, and check the pinout since equivalents in the same package do not always share the same lead order.
