PDF reference for the 1SV329 diode, listed among schematics though its size suggests a concise data sheet. The 1SV numbering comes from the Japanese JIS registration system, and Toshiba uses this prefix for variable-capacitance diodes. Nothing besides the part number is encoded in the name. Repair work with such a sheet means verifying pin orientation, package dimensions and tuning range when a receiver or oscillator drifts or will not lock. Match the marking code on the original component before relying on the figures.
