Short 36.2 KB PDF covering the 2SK1605 transistor. The 2SK code identifies an N-channel FET under Japanese part numbering; beyond that the name says nothing about maker or package. The document should give pin assignment, ratings and characteristic curves, which help confirm whether a measured short is plausible and which equivalent parts are safe. Compare the body marking and case of the original before using these specs for a replacement.
