Short 31.7 KB PDF for the 2SK1460LS, an N-channel FET by the Japanese 2SK prefix, carrying an LS suffix that distinguishes it from the plain 2SK1460 also in this index. The suffix usually signals a variant such as a different package or grade, so compare both documents before substituting. Although tagged as a schematic, the file is most likely a brief datasheet with ratings and outline. Check the full marking, suffix included, on the actual part before relying on it.
