PDF of roughly 332 KB dedicated to the 2SJ610 part number and catalogued as a schematic. Following Japanese JIS designations, 2SJ indicates a P-channel FET, so the pages most probably hold electrical specifications and outline dimensions. Read it with any PDF viewer when diagnosing a shorted or open transistor, confirming pinout, or comparing voltage and current limits of a substitute. As the name states no maker, compare the code printed on the installed part before trusting the data.
