2N2222a NPN transistors characterized by low power consumption, high frequency, high current amplification and good linearity characteristics are commonly used in VHF (Very High Frequency) amplifiers and switching applications in digital circuits. With a low threshold voltage and large collector current, it is also widely used in LED drivers and small motor controls.
Pin | Symbol | Description |
---|---|---|
1 | Emitter | The primary function of this pin is to provide transistor current to the output load. |
2 | Base | The primary function of this pin is to control the current from the emitter to the base. |
3 | Collector | The main function of this pin is to discharge the full current from the transistor. |
The 2N2222a NPN transistors are available in three configuration modes including common emitter (CE), common collector (CC) and common base (CB). These three configurations enable functions such as amplifying voltage, current and power in applications according to different requirements.
