In a triggering circuit I’ll bet this could cause all sorts of weird behavior.

Please refer to datazheet Part Datasheet for an image of the part case and material composition information. I know this kind of thing happens. The data I have on the calls it a “bulk” device.

I gathered from what I found that the BC series is popular for its low noise. I checked that and it is the reason that I did not also recommend the 2N or 2N although I suspect both would work fine without adjusting the circuit. The characteristic curves for old parts and new parts like the 2N could be compared to see if the processes was changed but that will not be reliable if newer published data was not updated to reflect changes. If your ATE can only measure leakage down to 50 or nanoamps common values in the datazheet time, then that becomes your guaranteed maximum specification.

I wonder if that is just a testing difference. Robert Pease wrote that he kept a collection of “worst case” transistors for testing circuits.

That might be very helpful information! I did this for the 2N and found them to be identical between and so I datasyeet assume Fairchild is either still using process 23 or they never updated the documentation. This is great, since the BC is a sort of rugged monster of a TO, and it even has a complementary part.

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.

Almost all of the transistors in the parts list say selected. I’ve got a few NOS if anyone needs a replacement. Subject of the new topic: A 2N from anyone else was NOT a A BC is going to be a little slow. I’m very hesitant to use this part number in any design for that reason, as it’s likely builders will just use whatever is available at the cheapest cost.

Do make sure that the Ft is taken at the right Ic for each transistor, because it increases with bias. You can save a lot of money or grief finding special parts if you grade them yourself. On 01 Nov My sources are of an anecdotal nature, so I mostly consider them as indications I should do my datqsheet tests.

I’ve heard OnSemi sometimes turns out parts at half-spec and that most of the botched parts come from factories in problem countries too bad I can’t remember which. Reason Report to Moderators I think this message isn’t appropriate for our Group.


First time users please use the quick and easy one time website registration. The BD is a transistor which almost every manufacturer seems to have their own different datasheet eatasheet, so if it’s a critical part, sometimes you have to know the manufacturer and not just the part number. The Fairchild 2N specifications just yield a minimum of MHz. I should have paid closer attention. Differences between transistors on the same process were just geometry and National included drawings showing that as well.

Your email is included with the abuse report. National used to publish which processes each transistor was built on and the associated process curves. One of my projects on standby is to design and build a semiconductor analyzer which can measure these kinds of parameters. The image for is currently unavailable. At any rate, do compare datasheets between manufacturers.

So it would make sense the 2N wouldn’t need selected unless there was past experience with inferior parts.

I wish this kind of information was unambiguously available for modern parts. 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 datasheef. On Thu, 31 Oct
