Toshiba-style 1SV324 documentation in a 71 KB PDF, catalogued under schematics. 1SV is the Japanese JIS designation for diodes, applied in this range to varactor diodes whose capacitance changes with reverse bias. The file name states no package type or document version. Such a sheet helps a technician identify the part by marking code and orient the cathode correctly. It also shows whether an available substitute covers the same capacitance span, so compare it with the original before ordering.
