Working Principles

The TRS202ECN is a bipolar junction transistor (BJT) that operates based on the principles of amplification and control of electric current. It consists of three layers of semiconductor material, namely the emitter, base, and collector. By applying a small current at the base terminal, the transistor can control a larger current flowing between the collector and emitter terminals. This property allows the TRS202ECN to amplify weak signals and provide signal conditioning in electronic circuits.
