A 61.3 KB PDF for the 1SV250, placed in the schematic category by the index. Following Toshiba's numbering, the 1SV group covers variable-capacitance diodes, so expect a data sheet rather than a circuit diagram. Technicians use such documents to identify package pins, decode surface-mount marking codes and compare capacitance at specified voltages. That comparison is essential when hunting for a substitute in a PLL, VCO or tuner front end. The file name has no revision or variant information. Any PDF reader works.
