Basics of BC547
Hello friends, I hope you are all doing great and having fun in your lives. In today's tutorial, I am gonna discuss a new electronic component named as BC547. It's a BJT transistor and is normally used where fast switching is required. If you are using this transistor in your Engineering Project then I would suggest you download this Proteus Simulation of BC547 because it's always a better strategy to work on simulation first before going on to hardware. So, let's have a look at the basics of BC547. Here's the pinout Diagram of BC547:
Basics of BC547
Here are the key points which you must know about BC547:
- BC547 is a Bipolar Junction Transistor, abbreviated as BJT.
- It is an NPN transistor.
- It has three terminals named as:
- The maximum current gain of BC547 is 800A.
- Collector-Emitter Voltage is 65V.
- Collector-Base Voltage is 80V.
- Emitter-Base Voltage is 8V.
Working of BC547
BC547 has two working states which are:
- Forward Biased.
- Reverse Biased.
In a forward biased state, the collector and emitter are connected allowing current to pass through. While in a reverse biased state, it works as an open switch and doesn't allow the current to pass.
Applications of BC547
BC547 is normally used for:
- Current Amplification.
- Fast switching.
- Pulse Width Modulation.
So if you have some project in which you wanna control the speed of a motor or actuator then you can easily do that by using this transistor. Moreover, it is also used as a switch i.e. if you want to turn on or off DC appliances then you can easily do that using this transistor.
I hope you have enjoyed today's tutorial. If you are working on this transistor and got into some trouble then ask in comments and I will try my best to resolve it. Will meet you guys in the next tutorial. Till then take care and have fun !!! :)
