Working Principles

The QT150-D is a bipolar junction transistor (BJT) amplifier that operates based on the principles of current amplification. It utilizes the properties of a semiconductor material to amplify weak input signals. The base-emitter junction acts as a diode, controlling the flow of current through the collector-emitter junction. By applying a small input voltage to the base, the transistor amplifies the signal and produces a larger output voltage.
