Covering the 1SV263, this 64.7 KB PDF sits in the schematic category, though its name and size point to a single-component document. The 1S prefix identifies a diode in JIS numbering, and Toshiba uses the 1SV designation for variable-capacitance types. Expect ratings tables, characteristic graphs and an outline drawing. Repair technicians consult such sheets to verify polarity, decode SMD markings and compare capacitance ratio and series resistance before fitting a replacement in RF circuitry. Any PDF viewer is enough.
