Compact UTC datasheet, around 14 KB, for the 2SD880 NPN transistor from Unisonic Technologies. The 2SD prefix in JIS nomenclature marks an NPN device for low-frequency applications, commonly found in audio, power supply and driver circuits. The sheet lists the pin configuration, maximum voltage and current limits and gain grouping a technician needs when checking a suspected failure or sourcing a substitute. Confirm the package and pin order on the actual board before fitting a replacement, as layouts vary.
