Covering the 1SV322, this 71 KB PDF is indexed as a schematic but is most likely the component data sheet. Diodes carrying the 1SV prefix are JIS-registered, and Toshiba uses the range for varactors in RF tuning and oscillator circuits. No package, version or status is given in the name. A repair technician uses the sheet for the marking code, pin assignment and reverse-bias capacitance table. Check the footprint and marking against the part on the PCB before soldering in a substitute.
