Can I use BC547 instead of 2N3904?

The datasheet for the 2N3904 shows that its current gain is barely enough to use a resistor as high as 100k in that circuit so even more light would be needed to turn off the transistor. A BC547C has much more current gain and will work better.

What is BC in BC547 transistor?

If you are a maker, you like DIY and electronics, surely you have ever needed to use a BC547 transistor. It is a bipolar junction transistor that was originally developed by Philips and Mullard between 1963 and 1966. In addition, for its acronym BC It shows that it is a silicon transistor (B), for low frequency (C).

What is the difference between 2N3904 and 2N3906?

camere. As people said that the basic difference between 2N3904 and 2N3906 is that former is NPN transistor and later is PNP.

The 2N3906 is a commonly used PNP bipolar junction transistor intended for general purpose low-power amplifying or switching applications.

What is the difference between 2N3904 and 2N2222?

2N3904 can handle up to 200mA (milliamperes) of current flowing from the emitter to the collector terminal. A 2N2222 can handle up to 5 times that amount of current, as it can handle up to 1A (amps) of current flow from emitter to collector to power a load.

Which transistor can be used in place of 2N2222?

The 2N2907 is an equally popular PNP transistor complementary to the 2N2222. The 2N3904 is an NPN transistor that can only switch one-third the current of the 2N2222 but has otherwise similar characteristics.

What type of transistor is 2N3906?

2N3906 Transistor is a popular PNP bipolar junction transistor used in low power and current, medium voltage applications. It is widely used for low power amplification and switching. 2N3906 is complementary to 2N3904 NPN bipolar junction transistor.

How does the 2N3904 compare to the BC547?

Its electrical properties compare much more favourably with the BC547, where Vcbo = 50 V, Vces = 50 V, Vceo = 45 V, Vebo = 6 V. This is similar to the characteristics of the 2N3904 where Vcbo = 60 V, Vceo = 40 V, Vebo = 6 V. However, the BC550 is an even closer match with Vcbo = 50 V, Vceo = 45 V, Vebo = 5 V.

What does hFE mean in transistors?

hFE is an abbreviation, and it stands for “Hybrid parameter forward current gain, common emitter”, and is a measure of the DC gain of a junction transistor. So on a multimeter, it indicates a mode where the meter can measure (probably crudely), the HFE of a transistor.

Can I use C945 instead of 2N2222?

C945 is a general purpose small signal NPN transistor, pretty much like the 2N2222 .. The difference is in the max continuous current: C945 – 150ma, 2N2222 – 500mA .. But if you switch a couple of mA, say, below 100mA, there is not much difference between them ..
