Description
The BC547 is a general-purpose NPN BJT with a voltage rating of 45V and a maximum current rating of 100mA. It has a low collector-emitter saturation voltage, which reduces power loss and improves efficiency. This device is designed for use as general purpose amplifiers and switches requiring collector currents to 300 mA. Sourced from Process 10. See PN100A for characteristics.
Features
1. Switching and Amplifier
2. Collector-Base Voltage : Vcbo = 50V
3. Collector-Emitter Voltage : Vceo =45V
4. Emitter-Base Voltage: Vebo = 6V
5. Collector Current (DC) : Ic = 100mA
Disadvantages
1. The BC547 is designed for low-power applications and may not be suitable for high-power circuits.
2. Its maximum current rating of 100mA may be too low for some applications.
3. It has a relatively low maximum voltage rating of 45V, which may limit its use in some circuits.
