Working Principles

The MP155GS is a bipolar junction transistor (BJT) that operates based on the principles of amplification. It consists of three layers of semiconductor material: the emitter, base, and collector. By applying a small input current at the base terminal, the transistor can control a larger output current flowing between the collector and emitter terminals. This amplification process allows the MP155GS to boost weak signals while maintaining signal integrity.
