Working Principles

The BU1CTD3WG-TR is an NPN transistor that operates based on the principles of bipolar junction transistors (BJTs). When a small current flows into the base terminal, it controls a larger current flowing between the collector and emitter terminals. This amplification effect allows the transistor to amplify weak signals.
