Working Principles

PA99 is an NPN transistor that operates based on the principles of bipolar junction transistors (BJTs). It consists of three layers of semiconductor material - the emitter, base, and collector. By applying a small current to the base terminal, the transistor allows a larger current to flow between the collector and emitter terminals. This amplification of current enables the transistor to amplify weak input signals.
