I’ve heard OnSemi n23251 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. Differences between transistors on the same process were just geometry and National included drawings showing that as well. Unfortunately I don’t have any references. If you used, say, ait would be made by one of those manufacturers.
Bipolar NPN RF transistor, TO-18
Alternate Devices with Different Packaging:. In order to better serve you, we have created a new web based request system. OnSemi makes some inferior versions of some transistors, Fairchild makes other inferiors of some other transistor. I do audio stuff dwtasheet and some popular DIY circuits are a bit more sensitive to transistor specs than a working engineer would have patience for.
I adtasheet Tektronix was pushing the edge so much as just running their own quality control program on incoming parts. The BC3x7 series typically has low internal base resistance which is why it’s not very noisy. 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 in repair and design work.
On 31 Oct I found some audio related discussions about matching between Fairchild and On Semiconductor BC and BC series transistors which mentioned the large Ft variation but nothing detailed.
Click to view availability. Some specifications like leakage and noise are difficult to test quickly so their guarantied minimum or maximum values reflect testing limitations.
Real-Time Measurement and Control
I have often had to qualify 22n3251 by manufacturer. On 01 Nov Some in this field do their research on transistor manufacturers and it is much more often than you think that you catasheet get a counterfeit, unexpectedly inferior part, or even a bad batch if you’re not careful about your source. The new topic will begin with this message.
A BC is going to be a little slow. Reason Report to Moderators I think this message isn’t appropriate for our Group.

Often the only difference between premium parts and others is testing time and grading. Do make sure that the Ft is taken at the right Ic for each transistor, because it increases with bias.
This could just be a case of out-of-date documentation. The 2N looks like a good bet. I wish 2n32251 kind of information was unambiguously available for modern parts. I do the same thing when drawing up parts lists and spend some time qualifying alternative parts and sources. In order to better serve you, please access the online inquiry system.
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 for, so if it’s a critical part, sometimes you have to know the manufacturer and not just the part number.
Some companies are better about announcing ddatasheet process changes than others but I think the tenancy over time has been to hide more of this information. 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.
Your email is included with the abuse report. Thursday, October 31, 9: National used to publish which processes each transistor was built on and the associated process curves. I wonder if that is just a testing difference. This cannot be undone. Click here to access our new inquiry page. I was not able to find any current Fairchild process documentation.
