Reference PDF of 111 KB for the 2SK1444, filed in the schematic section and most likely its complete data sheet. The 2SK code identifies an N-channel field-effect transistor under JIS conventions. A separate LS variant sheet also exists. Expect maximum ratings, electrical characteristics and package dimensions. Repair technicians use these to read pin positions, verify voltage and current capability, and assess equivalents. Confirm the device marking, including any suffix, before ordering a part.
