Documentation for the 2SK2624LS, provided as a 42.8 KB PDF in the schematic category. The 2SK part of the number is the JIS designation for N-channel field-effect transistors, while LS identifies a specific variant of the 2SK2624, frequently a package difference. Inside should be ratings, characteristics and an outline with pin numbering. It is useful for testing and substitution work on power circuits. Compare the drawn package against the physical part on the board first.
