Source for transistor outline dimensions needed

[hr(bob) hofmann@att.net]

Can anyone give me an address for a source that gives the dimensions
of various transistor cases, TO-5, etc? I struck out using Google.

Dayum!

I tried every trick I could think of:

"standard semiconductor packages" *
"standard transistor outlines"
"transistor outlines"
to-3 to-220
ieee iso

and a bunch more. Nada. Zip. Zero.

Who the hell is the keeper of those standards? I woulda thought it would
be an ISO standard, or perhaps IEEE.

Hi Dave:

I tried everything I could think of, I'm not sure who sets the
standards, and I am an IEEE member and then some. Yes, I use
"asdhjkfashjdf" frequently.

That would be JEDEC Publication 95. The sections are available for

Googling for "jedec transistor dimensions TO-5"
gave me e.g. this

http://www.tpub.com/content/MIL-SPEC/MIL-S/MIL-S-19500-69E/MIL-S-19500-69E00003.htm

They give a drawing with dimensions of TO-5. I guess that most,
if not all, of case types can be found out that way. Any drawbacks?

H.

Yes, get a data sheet for one. The major semi manufacturers all publish
detailed dimensions.

I have a number of known good, but unknown types of transistors,
scrapped from working electronics that I did not want to keep or pass
on to Goodwill. I googled on the codes on the transistors, but got
too many replies. I thought if I could figure out which TO-XXX the
cases were, I would narrow my search somewhat. I don't know the case
sizes by just looking at them as I normally do not worry about the TO-
XXX case when replacing known transistors. I will try the JEDEC site.

There are only a few relatively popular ones. Some Japanese or European
devices may have non-JEDEC specified cases. And some manufacturers, notably
Motorola at one time had 'in-house' case designs.

Please consider alternatives to Goodwill for electronics donations; its
good that you are diverting materials from the recyclers, but Goodwill
has become unresponsive and uninterested in serving the customer that
seeks surplus electronics and is denying most electronics donations
in many regions and those areas where it is still handled, the sale prices
have often become excessive for materials that are often unserviceable.

Our local daily paper has a free-to-run swap and donation section and
is a popular route for electronics donations; craigslist is another
alternative and many areas have local citizen web presence free
classified adverts.

I encourage everyone with interest in maintaining a vibrant electronics
reuse ethic to write to your area Goodwill management offices to complain
and request a sane policy towards electronics donations.

Regards,

Michael

If you follow the links, it's easy to drill down to just the one-page
pdf for a given type; downloading the entire volume isn't required.
Nonetheless, the answer to "who sets the standards" is JEDEC.

I am located far from the problem, but from what I have read in the last
few years, Goodwill and similar organizations have become the dumping ground
for unusable, unrepairable, electronic trash which costs them money to recycle.

Many of them have stopped accepting anything electronic that can not be
sold for enough money to cover the cost of legally getting rid of the parts
that come with it that are of no value.

Quite simply, unless you are willing to volunteer the time to sort it for
them and dispose of the nonsaleable stuff, the only sane policy is to
refuse any donations of electronics.

There are places that do exactly that.

F'rinstance, my favorite recycled-goods vendor, Urban Ore in Berkeley,
has tons of electronic equipment, all sold "as-is" with no guarantee of
working or not. Much of it does work; a lot of stuff is "vintage" (like
old tube-operated equipment), so you takes your chances with it. In any
case, they move a lot of stuff through their store.

Obviously they need to get rid of a lot of electronic crap that doesn't
sell. Turns out that at least here (Alameda County), there are funded
programs which handle consumer electronics waste. There's a place in
Berkeley where I can take any electronic stuff--computer monitors, PCs,
TVs, etc.--for disposal, for free, no questions asked.

Too bad this isn't the case everywhere.

Indeed, and I have _volunteered_ to do sorting, create lists of important
material types, suggested methods of handling and distribution that are known
to work and were used at Goodwill until a change of management, but in all
cases have been ignored. Just about _everything_ electronic that has appeared
as donations at our local Goodwill distribution center is wanted by experimenters
and would be cheerfully taken in a 'free bin' as opposed to being a liability
and expense to the organization for disposal.
