Bipolar Junction Transistor

Base, Emitter, Collector
  • NPN: Not Pointing iN
  • PNP: Pointing iN Please
  • The arrow is for the emitter current. For an NPN the current flows into the collector. For a PNP the current flows out of the collector.

NPN Active Region

  • Base-emitter junction is forward biased
  • Base-collector junction is reverse biased
