Part reference for the 2SK1452 in PDF form, 111 KB, classified as a schematic. The name states only the device number. Following JIS conventions, the 2SK prefix denotes an N-channel field-effect transistor, so the pages most likely list ratings, electrical parameters and mechanical outline. Technicians lean on such data when a MOSFET in a supply circuit reads shorted and an equivalent must be chosen with equal or better drain-source voltage and current. Double-check the part marking against this number first.
