A 417 KB PDF on the 2SK2967 transistor. The name gives only the part code, and 2SK designates an N-channel FET in the Japanese JIS scheme, so this is a component datasheet rather than a device schematic. Technicians rely on such sheets for drain-source breakdown voltage, drain current, RDS(on) and gate threshold when repairing power supplies or inverters, and for package dimensions when fitting a substitute. Confirm the marking on the failed part first.
