A 70 KB PDF on the 1SV311 diode, catalogued in the schematics section. The 1SV prefix comes from the Japanese JIS registration system and is used by Toshiba for variable-capacitance diodes in tuners and voltage-controlled oscillators. Package and revision are not stated in the name. Use it to verify marking code, cathode pin and reverse voltage limits on the part you are testing. Check its capacitance figures against any proposed replacement before soldering a new component in place.
