Which transistor can be used in place of BC548?
For BC547 it is 100mA and for BC548 it is 500mA. This indicates that BC548 has higher emitter current and can handle higher currents than BC547. The BC547 transistor can have higher voltages on the collector terminal than BC548, but this particular specification will not stop replacing the BC548 with BC547.
How do I use BC548?
- BC548 is a NPN transistor so 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.
- When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above.
What is transistor BC548?
The BC548 is a general-purpose NPN bipolar junction transistor commonly used in European and American electronic equipment. It is notably often the first type of bipolar transistor hobbyists encounter and is often featured in designs in hobby electronics magazines where a general-purpose transistor is required.
What is 547 BC547 transistor?
A transistor, stands for transfer of resistance, is commonly used to amplify current. A small current at its base controls a larger current at collector & emitter terminals. Bc547 is mainly used for amplification and switching purposes. It has a maximum current gain of 800.
What is BC548 transistor?
What is the equivalent transistor of BC548?
BC548 Equivalent Transistors BC549, BC636, BC639, 2N2222 TO-92, 2N2222 TO-18, 2N2369, 2N3055, 2N3904, 2N3906, 2SC5200 Brief Description of BC548 BC548 is a NPN transistor so 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.
What is the value of V be for BC548?
Where, the value of V BE should be 5V for BC548 and the Base current (I B depends on the Collector current (I C ). The value of I B should not exceed 5mA. A Transistors acts as an Amplifier when operating in Active Region. It can amplify power, voltage and current at different configurations.
What is the difference between a BC548 and a 2N3904?
A BC548 can switch up to 100-mA of drive current, the 2N3904 can switch up to 200-mA drive current. To use a LDR, we usually make it part of a Potential Divider (PD) network consisting of a fixed resistor R.
Can a transistor be used as a switch?
When a transistor is used as a switch it is operated in the Saturation and Cut-Off Region as explained above. 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.
