It’s a low voltage NPN transistor that is primarily common in audio amplification. Thus, it is a class B Push-Pull audio amplifier. Nonetheless, it is also a general-purpose transistor that is useful in a variety of electronic circuits.
Also noteworthy is that the transistor is a semiconductor. Thus, applying a positive current at the collector terminal will yield a current flow to the emitter. Hence, it operates differently from the common PNP semiconductors.
The S8050 falls under the bipolar junction transistors (BJT) category. Therefore, it possesses two charge carriers.
