What is the difference between bc and 2nA transistor. Then you should learn how to read datasheets in general. This question does not appear to be about electronics design within the scope defined in the help center.

So your application defines your selection in such cases. The larger the resistance value of the emitter resistor, the less the performance depends on hFE. Do not remember what the is and never heard of the other device. How each transistors are selected for each project?

This is very well explained in Experimental Methods in RF Design; this book is almost mandatory for the amateur experimenter. Can i use 2nA instead of bc?

Without a curve tracer, how can you design a bc3477 A amp to compensate for variations in parameters such as hfe and hie? However, that would be the best bet. Finally you have to compare the datasheets of multiple transistors to determine which one suites your requirements best.

W8NSIApr 20, Would I be able to substitute 2n or a 2n for a bc and still use the same resister values in the circuit?

You can have a look at the datasheets: How would I know what hfe value to use? First you should understand how transistors work and what their key parameters are.

Read the datasheets carefully and make your choice. If this question can be reworded to fit the rules in the help centerplease edit the datashwet. W8NFApr 20, PNP’s have the emitter arrow pointing in and used with a – supply to the collector. 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 cb347 matter.

I have use bc for a project Water level indicator.

What does comparing the datasheets tell you? The basic difference is the 2NA is explicitly labeled “switching mode transistor”, which explains the much higher collector current in the same casing.

Your name or email address: As far as changing types, the A is an NPN device. In a class-A feedback amplifier, Hfe makes little difference. W0LPQApr 20, It is hard to tell you how to design something, when we don’t know exactly what you have, what your intentions are Just stick it in and see if it works transistors only. One has to expect bad linearity and high output capacitance from that.

Home Questions Tags Users Unanswered. The data sheets for several transisters I’ve been looking at don’t make the hfe value very clear. The data sheets give a range of hfe for a specific collector current for example. Does the usual design techniques for say a common emittor amp already take this into account?

W9GBApr 20, Most datasheets provide a list of typical use cases for the component.

Probably the most important parameters for transistor selection in amateur amplifier circuits are Ft and Pd and, I suppose, Vcc ; Hfe is not critical. K8ERVApr 20, Register for a free QRZ account.

OpenForm Good luck with your project. Looking at the data sheets, you should be able to substitute with minimal changes.

You’re right – hFE varies a tremendous amount, depending on Ic and temperatures. You can have a look at the datasheets:.

Some people don’t like to hear the word read The book is used as an “introduction to diodes, bipolar and field effect transistors” at community colleges.

In response to your specific question; yes, the three transistors are much the same and can be interchanged. When you see a parameter like that which appears poorly-controlled then there’s only one possible answer – common circuits are available whose performance is independent of the parameter.
