The maximum Collector current limit of BC547 is 110mA, so the load must be lower than that.In Forward Biased State, the current will start flowing from Collector to Emitter.If a HIGH signal(normally 5V) is provided at the Base Terminal, Collector and Emitter will start acting as a closed switch and the transistor is said to be acting as Forward Biased.In a Reverse Biased State, no current will flow through the transistor.If Base Terminal is connected to the Ground(0V), Collector and Emitter will act as an open switch and the transistor is said to be acting as Reverse Biased.Depending on the voltage applied at Base Terminal, BC547 can operate in two states, named:.BC547 Pins(Terminals) from left to right are called:.BC547 is a 3-Terminal NPN Bipolar Junction Transistor(BJT), mostly used for switching purposes and current amplification.So, let's have a detailed overview of BC 547. It is an NPN bipolar junction transistor (BJT), mainly used for switching and current amplification. Today, I am going to give you a detailed Introduction to BC547. *This information is for general informational purposes only, we will not be liable for any loss or damage caused by the above information.Hello everyone!
