Pinout needed for TO-5 devices

[DaveC]

I'm looking for pinout data for 2N333, 2N336, and 2N324. All are stated as
being TO-5, a variant, AFAIK, of TO-92. All three of these are discontinued
numbers.

When I check NTEINC.com for a cross, I get NTE123A in a different package:

http://www.nteinc.com/graphics/diag21a.gif

National Semi and some others came up blank re. package data.

Where can I find the original pinout for these 2N devices?

(Which raises a general question: are all pinouts for all TO-5 devices the
same?)

Thanks,

Thomas,
Thanks for your reply.

I was not clear in my request. The 324, 333, and 326 are all plastic,
"D-shaped" form factor. Is this TO-92? Is TO-5 only round metal? The only
pinouts I could find match your data, but not the devices on my PCB.

I need pinouts for these 3 device numbers in the black plastic "D-shaped"
form factor.

Thanks again for your effort,

Are you kidding?
Of course not!
That would make too much sense.

I concur with the typical pinout for the TO-5 transistor except for the
comment about the base being connected to the case......usual situation
would be that the collector was connected to case.....wonder if that was
just a typo (I'm fairly expert at those!).

YES it is most likely TO-92

YES

Perhaps you are having trouble because you are using
the wrong names for the case types.

Dave, those part numbers were obsolete by 1970, so I don't have any
data on the case, but I do have their basic data in the 1970 Motorola
Semiconductor Data Book.

The 2N324, 2N326, and 2N333 are JEDEC registered devices, so their
housings should always be TO-5.

If you have plastic housed versions of the devices, then they are most
likely TO-92. The problem with that is that there are (according to
National's 1993 Discrete products databook) three pinout footprints for
the TO-92 package, the TO-92(92), the TO-92(94), and the TO-92(96).

Looking at the flat of the housing with the legs pointing down, the
TO-92(92) pins out EBC from left to right, the TO-92(94) pins out ECB,
and the TO-92(96) pins out BEC. So, to sort out what's what you'll
probably need to get into the thing's guts and do a little reverse
engineering.

The 1964 GE Transistor Manual has spec's for all three in case you need
to get equivalents, and "3" in their "Dwg.No." column corresponds to
TO-5. Unfortunately, they didn't list the package for the 2N326 but
it's rated for 7 watts so, clearly, it won't be in a TO-5 can. Much
less in a TO-92 package! I've scanned the page and I'll post it to
alt.binaries.schematics.electronic sometime today.


The spec's for the 2N326 are at:
http://www.dscc.dla.mil/Downloads/MilSpec/Docs/MIL-PRF-19500/mil19500ss40.pdf
http://www.dscc.dla.mil/Downloads/MilSpec/Docs/MIL-PRF-19500/mil19500ss40am1.pdf

which makes me think that if you're looking at something in a TO-92
package that has 2N326 written on it, then there's something drastically
wrong!

The definitive spec's for the 2N333 are at:
http://www.dscc.dla.mil/Downloads/MilSpec/Docs/MIL-PRF-19500/mil19500ss37.pdf


P.S., I haven't forgotten about your schematic, I just haven't gotten a
round tuit... BTW, is that 24VAC relay what you have in mind for
shunting the resistors?

They should be whatever the drawing specifies. TO-5 for the 2N324 and

I misprinted: it's not "326", but rather "336".

These all have the National logo (NS) followed by either "333", "324", or

Not a safe presumption. They could be "house numbers"
or even a date code. (Date codes are sometimes encoded.)

Where did they come from? Those numbers sound too low
(old) to be in modern TO-92, IMHO.

Well, the TO-39, which looks identical to the TO-5, will easily handle
7 watts, with a heatsink of course. The TO-39 case has the chip
bonded to the header, so the collector lead is usually welded directly
to the case.

AAMOF RCA made the 2N4036, 40412, 40346, 40347, & 40412 among many
others, all of which were in a TO-5 case and rated for a dissipation
of 7W or greater, in some cases 10W. This _was_ a true TO-5 case.

These all have the National logo (NS) followed by either "333", "324", or
"336". I presume that they are all 2N devices.

First off, the 2N300s were germanium, with the exception of the Texas
Instruments 2N333 thru 338 series. Germanium transistors could not be
passivated like a silicon can, so they were almost always mounted in a
hermetically sealed metal container. If they were germanium and
mounted in a plastic container, they would not last long, after a
short time the plastic would contaminate the junctions.

So that means it's unlikely that these transistors were germanium.

The problem with that is that there are (according to
National's 1993 Discrete products databook) three pinout footprints for
the TO-92 package, the TO-92(92), the TO-92(94), and the TO-92(96).

Hogwash. I suggest you get a data sheet for a 2N4036 and take a look at
power dissipation VS case and ambient temp.

Here's one from Motorola

http://212.57.231.17/datasheets/67/OWOSNOVWOP.pdf

and even though they've got the Ta and Tc curves labeled backwards it
might give you a clue. Besides, I don't think the OP mentioned anything
about a heat sink, so even if it _was_ TO-5 instead of TO-92 it would be
operating in an enclosure at a Ta of >25° C, which means he wouldn't
even be able to get a watt out of it.

Checking National's site to see if they may be ICs:

LM333 - negative voltage regulator, TO-3 (no TO92 package listed)

LM336 - 2.5 volt voltage reference available in a TO 92 package.

LM324 - quad opamp - needs more than 3 pins, so not your part.

The Motorola spec. says max Vceo is -65V and max. current is 100mA. That
works out to 6.5W. Specs, though, may vary from manufacturer to
manufacturer.

Max power diss. is usually spec'ed with a case ambient of 25C. Kinda
hard to maintain this with any kind of long term lifetime. Many times
curves for various specs are extrapolated from lower power settings,
currents and the like for marketing purposes. Beware if you try to use a
component at its max ratings.

Well, the TO-39, which looks identical to the TO-5, will easily handle
7 watts, with a heatsink of course.

The datasheets from the 60's and 70's often have such nonsense in the
bold type at top. If you read down further you see that this spec only
applies if you keep the case at 25C... which given typical TO-5 heatsinks
means an ambient temp below -60C if the average dissipation is 7 watts
for even a fraction of a second. And that the measurements above
the half-watt level were made using pulse techniques.

The 1964 GE Transistor Manual has spec's for all three in case you need
to get equivalents, and "3" in their "Dwg.No." column corresponds to
TO-5. Unfortunately, they didn't list the package for the 2N326 but
it's rated for 7 watts so, clearly, it won't be in a TO-5 can. Much
less in a TO-92 package! I've scanned the page and I'll post it to
alt.binaries.schematics.electronic sometime today.

I have only one thing to say. Read the 2N4036 data that I posted to
ABSe.
