Transistor B547 - Pack of 10:

he BC547B is a common NPN bipolar junction transistor (BJT) used in electronic circuits. It is part of the BC series of transistors, and the BC547B is a variant of the BC547 transistor. Here are some key specifications for the BC547B:

1. Type: NPN (Negative-Positive-Negative) transistor.
2. Package: TO-92, which is a standard small plastic package for transistors.
3. Polarity: The collector is typically connected to the positive supply voltage, the base is used to control the current flow between the collector and emitter, and the emitter is connected to the ground or common reference.
4. Maximum Collector Current (IC): Around 100mA.
5. Maximum Collector-Emitter Voltage (VCE): Typically 45V.
6. Maximum Collector-Base Voltage (VCB): Typically 50V.
7. Maximum Power Dissipation (Ptot): Around 500mW.
8. Gain (hfe or β): The forward current transfer ratio is typically between 110 and 800, depending on the specific transistor.
