PDF for the 1SV316, catalogued under schematics, with UV and sot323 added to the name. SOT-323 is a small three-lead surface-mount package, while the UV token is not explained in the name. The 1SV prefix denotes a JIS diode, a series Toshiba uses for variable-capacitance tuning diodes. At 32 KB it is a compact sheet, useful for the package outline, pin orientation and capacitance characteristics. Confirm the marking code under magnification before replacing a part in a tuner or VCO.
