A 105 KB PDF for component 2SK1432, categorised as a schematic though the name identifies only a single transistor. Per the Japanese JIS convention, 2SK stands for an N-channel field-effect transistor. The name says nothing about manufacturer or case, so verify these within the file. Repair work commonly uses such a sheet to locate gate, drain and source when probing with a multimeter, to judge whether readings indicate a short, and to match ratings when sourcing an equivalent.
