PDF data for the 1SV323 diode, filed as a schematic and sized at about 71 KB. The part number uses the JIS 1SV prefix, which Toshiba assigns to its variable-capacitance diodes used for electronic tuning. Beyond the part number the name holds no detail. Open it in a PDF viewer to compare ratings, package drawing and capacitance curves with the component on the board. That comparison shows whether a cross-reference part will behave the same, so do it before replacing anything.
