- Signal processing: Modifying and manipulating electronic signals.
The datasheet provides key parameters that enable designers to choose the right transistor for their specific needs. For instance, you'll find information on:
- DC Current Gain (hFE): This indicates how much the base current is amplified by the collector current.
- Transition Frequency (fT): This tells you how fast the transistor can switch.
- Collector Saturation Voltage (VCE(sat)): The voltage drop across the collector and emitter when the transistor is fully 'on'.
Here's a simplified look at some typical values found in the 2n2222 BJT Datasheet:
| Parameter | Typical Value |
|---|---|
| VCEO (Max Collector-Emitter Voltage) | 40V |
| IC (Max Continuous Collector Current) | 800mA |
| hFE (DC Current Gain) | 100-300 |
Understanding these figures is fundamental to designing stable and functional electronic circuits.
