A 97.4 KB PDF for the 2SC3151, an NPN bipolar transistor according to its JIS 2SC designation. Although listed among schematics, a single part-number name like this normally means a manufacturer data sheet. The component is commonly marked C3151 on the body. Check the pin assignment and package outline in the file before desoldering, then test the junctions in diode mode. When substituting, make sure collector-emitter voltage, collector current and dissipation of the alternative are at least equal to those listed here.
