Small 29.4 KB PDF bearing only the part number 2sj146. The 2SJ prefix in Japanese JIS naming designates a P-channel field-effect transistor, so treat this as a compact datasheet rather than a circuit schematic. It likely covers pinout and essential ratings on a page or two. Use it to orient the meter probes correctly during testing and to vet substitutes; verify the marking and any suffix on the part itself before relying on the listed values.
