Working Principles

The PL123-05SC-R is an NPN transistor that operates as a signal amplifier. When a small input signal is applied to the base terminal, it controls the larger output current flowing through the collector-emitter path. This amplification process allows the transistor to boost weak signals and provide higher power levels.
