Working Principles

The PA98EE is an NPN transistor that operates as an amplifier in electronic circuits. It utilizes the properties of a semiconductor junction to amplify weak input signals. When a small current flows into the base terminal, it controls a larger current flow between the collector and emitter terminals. This amplification process allows the transistor to boost the strength of signals passing through it.
