Bipolar Junction Transistor
- 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.
How a BJT works
Large-Signal DC models
| Base-Emitter | Collector-Emitter | Region |
