Reference sheet for the 2SJ620 in PDF form, 345 KB, listed in the schematic category. The 2SJ prefix follows the Japanese JIS scheme for P-channel field-effect transistors, so the content is expected to be electrical characteristics, curves and package drawings rather than a full circuit. When a P-channel switch fails short or open, a technician reads ratings like these to find an equivalent. Nothing else is stated in the name, so match the package and marking on the real part first.
