Working Principles

The DS1020-25 is a bipolar junction transistor (BJT) that operates based on the principles of amplification and control of electrical current. 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 for the enhancement of weak signals.
