BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM). Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it. 
Features:
- Its bipolar NPN transistor
 
- Its current gain is 800 hFE
 
- Its collector current is 100mA
 
- Its emitter base voltage is 6V
