#BC547TRANSISTOR DRIVER#
Driver Modules like Relay Driver, LED driver etc.When uses as an Amplifier the DC current gain of the Transistor can be calculated by using the below formulaeĭC Current Gain = Collector Current (I C) / Base Current (I B) Applications Of the above types common emitter type is the popular and mostly used configuration. Some of the configurations used in amplifier circuits are It can amplify power, voltage and current at different configurations. BC547 as AmplifierĪ Transistors acts as an Amplifier when operating in Active Region. Where, the value of V BE should be 5V for BC547 and the Base current (I B depends on the Collector current (I C). The value of this resistor (R B) can be calculated using below formulae.
#BC547TRANSISTOR SERIES#
Anything more than 5mA will kill the Transistor hence a resistor is always added in series with base pin. As mentioned the biasing current should maximum of 5mA. As discussed a transistor will act as an Open switch during Forward Bias and as a Closed switch during Reverse Bias, this biasing can be achieved by supplying the required amount of current to the base pin. When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. When base current is removed the transistor becomes fully off, this stage is called as the Cut-off Region and the Base Emitter voltage could be around 660 mV. This stage is called Saturation Region and the typical voltage allowed across the Collector-Emitter (V CE) or Base-Emitter (V BE) could be 200 and 900 mV respectively.
When this transistor is fully biased then it can allow a maximum of 100mA to flow across the collector and emitter. To bias a transistor we have to supply current to base pin, this current (I B) should be limited to 5mA. KEC/FAIRCHILD - Get It Fast - Same Day Shipping Details DC current. The maximum amount of current that could flow through the Collector pin is 100mA, hence we cannot connect loads that consume more than 100mA using this transistor. A-137 In stock Qty Available: 979 Quick Overview. Brief Description on BC547īC547 transistor has a gain value of 110 to 800, this value determines the amplification capacity of the transistor. Note: Complete Technical Details can be found at the BC547 datasheet given at the end of this page.
BC547 Transistor Pinout Configuration Pin Number It does not store any personal data.BC547 is a NPN transistor hence the collector and emitter will be left open (Reverse biased) when the base pin is held at ground and will be closed (Forward biased) when a signal is provided to base pin.
