The 1SV287 part is covered by this 75.6 KB PDF, filed under schematics. Its 1SV numbering identifies a varactor diode, so the content is most likely a datasheet rather than a circuit diagram of a device. Expect absolute maximum ratings, capacitance at several reverse voltages, series resistance and package drawing with marking. Before ordering a replacement, read the marking on the original component and compare package size, as several parts in this series share similar codes but different curves.
