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.
Is BC547 and BC548 same?
BC547 and BC548 are essentially the same but BC547 has a higher breakdown voltage whereas BC548 has low noise. These are the most general purpose NPN silicon transistors and changing one with the other does not noticably (or otherwise) affect the circuit.
How do I use BC548?
BC548 is used in the following applications:
- Used in Darlington pairs to amplify weak signals.
- It can be employed in sensor circuits.
- Driving loads under 500mA.
- Used in audio amplification.
- Used in audio Amplifier Stages.
What is the function of transistor BC547 in the circuit?
BC547 is usually used for current amplifier, quick switching and pulse-width modulation (PWM). Therefore, if you need to control the speed of a motor or actuator in some of your projects, you can simply use this transistor to achieve it.
Can I use BC557 instead of BC547?
Can I use BC557 instead of BC547? Yes. You can use BC557 in place of BC547.
What is the gain of BC548 transistor?
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. BC548 has a gain value of 110 to 800, this value determines the amplification capacity of the transistor.
What should be the V be value 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.
What are the characteristics of bi-polar NPN transistor?
Bi-Polar NPN Transistor. DC Current Gain (hFE) is 800 maximum. Continuous Collector current (IC) is 500mA. Emitter Base Voltage (VBE) is 5V. Base Current(IB) is 5mA maximum.
What are the advantages of a 500mA collector current transistor?
The 500mA collector current is quite good feature for this size and type of transistor therefore you can drive wide variety of loads at the same time in an electronic circuit.
