Hello,

I am afraid there is a mistake in the small signal transistors data base.
The 2SA1321 is the PNP, and the complementary NPN should be the 2SC3334,according to the data-sheet.

Regards.
Alain.

Thanks Alain.

I had to do a lot of cut and pasting to add the links to the datasheets. I must have [ctrl]+[c] when I should have [ctrl]+[v].

Thanks for sharing this.

MPSA18 is, I think, a 625 mW device.

Hi Jim,

Yeah, the ON Semi MPS* datasheets have 2 power ratings. I picked the larger one but for a TO-92 device 1.5 watts does seems to large. What is the difference between Ta and Tc? Oh, I just worked it out, a = ambient and c = case. I wish all datasheets where consistent.

When you see the power ratings in the list, the MPS* stick out like dogs' and scream out there is a problem.

Very helpful, thanks ! May I suggest adding continuous collector current rating and Ft to the table of small signal devices. Perhaps a link to SPICE model when available, although I think I am asking too much 🙂

I agree that Continuous Current Rating and Ft, are important requirements in a short form reference.

I have already started, plus I am changing the order of the columns. 😉

here are some good ones for audio in production
PNP KSA992 F, E grades low noise
NPN KSC1845 F, E grades low noise

Thanks infinia, good ones, added P, F and E. 🙂

Double check them if you have a chance, I am starting to go cross-eyed.

mistake on the table new part KSC1845 not KSA


Seems it would make sense to include all the hfe grades into one row
FWIW the lowest hfe grade is rarely sold through premium resale channels, so I would exclude P grade from the list.

So for example the Hfe range of KSC1845
hfe range > / 300 to 1200 /
Notes > /low noise, hfe classes F,E,U/

Hi infinia,

Thanks for checking. I'll fix it as soon as I can.

I originally had all grades on one line and it made sorting on hfe less useful.

Fixed.

Plus, I change the column order so the NPN is first like the other tables. There was lots of cutting and pasting so I hope I didn't create any more problems.

Hi tiefbassuebertr,

Thanks for those. Some very interesting specs. I'll might have to quit my day job to give me enough time to keep up with you. 😀

Just thinking in advance, how much should I add to the tables. If these tables get too big would they still be still useful. Maybe a table of common transistors and another for the special ones. 😕

regards

A table of common transistors, that are currently in production and good available at the same time, and second table for the special ones - this might be a good approach.

But the term "good available at the same time" is strongly dependend of the individual region. Some types (mostly new types in SMD outline) are easy to find in Australia/Japan and hard to find in other countries and vice versa.

Also helpful would be a table, where I can see, which type belongs to which process. In old Fairchild data books this was clearly mentioned. E. g. concerning follow types: BD139, BC639 and BCP56 use an identical chip. Differences there are only by the outlines (TO126-TO92-SOT223 in this example). Today's data sheets don't mention this unfortunately.
Often I must find a solution to remove problems with burned amp PCB's in VAS stages, because TO-92 using. If there are such table, I can replace such transistors through identical electrical versions, but appropriate for heatsink mounting.

Without such a table I must hope, to find this by chance.

The NXP/Philips video types from post #1 about
http://www.diyaudio.com/forums/soli...ver-stages-high-power-amplifier-overview.html
seems to be also only differences concerning the outline.

 

[AndrewT]

I find the datasheet very useful to find the optimum range of Ic for highest hFE and range of Ic for highest fT.
Would that be asking too much? One extra column with an upper and lower Ic.

Does your Cob info all apply for the same Vce? Check whether the data is for 10Vce or 30Vce.
