Listed under schematics, this compact 57.2 KB PDF is titled with the part number 1SV252 followed by an underscore. Toshiba numbers its variable-capacitance diodes in the 1SV series, so the document is best read as a component data sheet. It is handy for confirming which lead is the cathode, matching the printed marking code and checking the capacitance swing against reverse voltage. Those checks matter before substituting another varactor in a tuner or oscillator stage. Any PDF viewer opens it.
