Reference sheet in PDF form covering the 1SV214, filed under schematics although at 75 KB it reads like a single-part data sheet. Parts with the 1SV prefix are JIS-registered diodes, a range Toshiba uses for varactor tuning diodes. Apart from the part number, the file name gives no package or version. Technicians use such a sheet to compare the bias voltage range, capacitance ratio and pin assignment with a suspect part in a tuner or VCO. Confirm the package outline matches the board footprint before fitting a replacement.
