George – All of the transistors you mentioned are small signal AF. Finally you have to compare the datasheets of multiple transistors to determine which one suites datwsheet requirements best.
If you need more current amplification for same biasing voltages you might want to go for 2AN. How would I know what hfe value to use? There is not much difference when it comes to electrical properties of the two transistors.
BC Datasheet, PDF – Alldatasheet
What does comparing the datasheets tell you? Can i use 2nA instead of bc? If this question can be reworded to fit the rules in the help centerplease edit the question. You can have a look at the datasheets: The data sheets give a range of hfe for a specific collector current for example. As far as changing types, the A is an NPN device. You’re right – hFE varies a tremendous amount, depending on Ic and temperatures.
Read the datasheets carefully and make your choice. The larger the resistance value of the emitter resistor, the less the performance depends on hFE. Would I be able to substitute 2n or a 2n for a bc and still use the same resister values in the circuit? Home Questions Tags Users Unanswered.
W0LPQApr 20, NTE on-line cross reference If you have a part number, it is quite easy to cross reference semiconductors.
Do not remember what the is and never heard of the other device. Here are some tips on how to read a datasheet.
BC347 Datasheet, Equivalent, Cross Reference Search
However, that would be the best bet. Some people don’t like bc47 hear the word read Your name or email address: W8NSIApr 20, This particular book goes through lots of theory and how things work. Difference between difference between bc and 2n [closed] Ask Question. The book is used as an “introduction to diodes, bipolar and field effect transistors” at community colleges. Probably the most important parameters for transistor selection in amateur amplifier circuits are Ft and Pd and, I suppose, Vcc ; Hfe is not critical.
NTE has a crossreference source on-line. So your application defines your selection in such cases. It is hard to tell you how to design something, when we don’t know exactly what you have, what your intentions are How each transistors are selected for each project?
OpenForm Good luck with your project. Write out the equations for the circuit at DC and you’ll be able to tell.
PNP’s have the emitter arrow pointing in and used with a – supply to the collector. W8NFApr 20, dqtasheet You can have a look at the datasheets:.
BC347 – TO-92 Plastic-Encapsulate Transistors
This is very well explained in Experimental Methods in RF Design; this book is almost mandatory for the amateur experimenter. One has to expect bad linearity and high output capacitance from datashdet. First you should understand how transistors work and what their key parameters are.
In a class-A feedback amplifier, Hfe makes little difference. Trivial questions that only require datashfet the datasheets should be closed. The basic difference is the 2NA is explicitly labeled “switching mode transistor”, which explains the much higher collector current in the same casing. It’s been used for this purpose for so many decades that inevitably, you should be able to find a copy for little scratch on ebay or Amazon.
Without a curve tracer, how can you design a class A amp to compensate b3c47 variations in parameters such as hfe and hie?
Making hFE less relevant The traditional low frequency amplifier with an emitter degneration resistor is designed so that hFE, as long as it’s above a nominally low value such as ten, does not matter. This question does not appear to be about electronics design within the scope defined in the help center. I have use bc for a project Water level indicator. The data sheets for several transisters I’ve been looking at don’t make the hfe value very clear.
Looking at the data sheets, you should be able to substitute with minimal changes. Does the usual design techniques for say a common emittor amp already take this into account?
