Pinout
The MJE340G is a high-voltage NPN bipolar junction transistor (BJT) commonly used in amplifier and switching applications. It has three pins:
1. Collector (C): The collector is the main terminal for current flow when the transistor is in the "on" state.
2. Base (B): The base is the control terminal that regulates the transistor's operation by allowing a small current to flow, which controls a larger current between the collector and emitter.
3. Emitter (E): The emitter is the terminal through which current exits the transistor.
The MJE340G is known for its ability to handle relatively high voltages up to 300V and has a maximum current rating of around 0.5A. Its primary function is to amplify or switch electronic signals in various circuits.
