The 2N2222 is a widely used bipolar junction transistor (BJT) that falls under the NPN (Negative-Positive-Negative) category. It is designed for general-purpose amplification and switching applications. The 2N2222 transistor is part of a family of transistors known as the "2N" series.
Here are some key specifications of the 2N2222 transistor:
Transistor Type: NPN
Maximum Collector-Base Voltage (Vcb): 60 volts
Maximum Collector-Emitter Voltage (Vce): 30 volts
Maximum Emitter-Base Voltage (Veb): 5 volts
Collector Current (Ic): 800 mA (continuous)
Power Dissipation (Pd): 500 mW
The 2N2222 transistor is often used in low-power amplification and switching circuits, such as small audio amplifiers, signal amplification stages, and digital logic interfaces. Its versatility, affordability, and wide availability have contributed to its popularity among hobbyists, students, and electronics enthusiasts.
