Datasheet in PDF form, 74.1 KB, for the 2SD1853 transistor from the Japanese 2SD family of NPN bipolar parts, filed here as a schematic. It lists the absolute maximum ratings, electrical characteristics and pin arrangement needed to confirm a substitute or find the base, collector and emitter on the board. Technicians use it when a power or driver stage fails. Read the marking on the original part carefully, because the gain grade suffix and package may differ from the drawing.
