Many other small-signal transistors are noisier, yet they are advertised as low-noise and the BC3x7 are not. My sources are of an anecdotal nature, so I mostly consider them as indications I should do my own tests. Actually, this circuit is a class AB follower.

I wish this kind of information was unambiguously available for modern parts.

The parts list in the service manual says “Selected from 2N”. By continuing to use our website, you agree with our use of cookies in accordance with our Cookie Policy.

That would have been important in test equipment with a high parts count. Cibo datashete be low for seamless switching, and Cobo must be low because it is the primary load of the driving stage at max bandwidth.

The Fairchild and OnSemi specifications are otherwise identical. Subject of the new topic: You can reject cookies by changing your browser settings.

At the same time, tubes were still used in this scope, so perhaps Tek was really pushing the edge at this time and it makes sense they may have selected their transistors in order to do that.

See TNA for characteristics. I gathered from what I found that the BC series is popular for its low noise. I wonder if that is just a testing difference.

I sure can because a quick search turned up a good electronic scan of the paper National Semiconductor Discrete Databook that I have although mine may be a slightly different year: You can save a lot dayasheet money or grief finding special parts if you grade them yourself. I’m guessing that datashedt switching speeds, the load capacitance was enough that it was necessary to have indefinite current output from this buffer.

This is one of the reasons I do not bother looking for NOS or exact replacement semiconductors. I would not bother with an exact replacement because it is operating as a simple emitter follower. The data I have on the calls it a “bulk” device.

What are the odds that Fairchild is still using anything approximating NS Process 12?


The Fairchild 2N specifications just dztasheet a minimum of MHz. In a triggering circuit I’ll bet this could cause all sorts of weird behavior. If you used, say, ait would be made by one of those dwtasheet. The 2N looks like a good bet. Robert Pease wrote that he kept a collection of “worst case” transistors for testing circuits.


National used to publish which processes each datadheet was built on and the associated process curves. Some in this field do their research on transistor manufacturers and it is much more often than you think that you might get a counterfeit, unexpectedly inferior part, or even a bad batch if you’re not careful about your source. Please refer to the Device Datasheet for an image of the part case and material composition information.

At any rate, even datasheet curves are often not the same as the real device, so it helps to be “street wise” or you may end up accumulating mysterious problems dataaheet repair and design work.

I should have paid closer attention.

Here is data on the 2N which matches the specifications Tektronix gives for the A Central sales representative will confirm the availability of the plating type requested.

Even with the same manufacturer, a part may be moved to a new process changing its unguaranteed characteristics significantly.
