Datasheet in a 33.2 KB PDF for the 2SK1967, a Japanese-registered N-channel field-effect transistor indicated by the 2SK prefix. Its catalogue type is schematic, yet the content concerns a single part. Consult it for pin assignment, package outline and maximum ratings when a FET has failed in a power supply or driver stage and a replacement must be chosen. The name carries only the part number with no maker or variant, so confirm the code printed on the original device first.
