Working Principles

The BC856BS/DG/B2,115 operates as a small-signal NPN transistor. When a small current flows into the base (B) terminal, it controls a much larger current flowing between the collector (C) and emitter (E) terminals. This amplification effect allows the transistor to act as a signal amplifier or switch in electronic circuits.
