A 67.7 KB PDF indexed under schematics and named 1SV233, with nothing else identifying a product or board. The 1SV prefix is a designation commonly used for variable capacitance diodes, so expect single-component reference data rather than a circuit diagram. Typical contents are the package outline, pin polarity and capacitance figures across reverse voltage. Repair use includes confirming orientation when refitting, judging a suspect diode in an RF or tuning section, and selecting an equivalent. Match the marking first.
