I need transistor SIV300004

Oh, please email if you have one/any as I don't check here often.

Thanks for any help.

:or equivalent. I only need one but would like to have some spares. : :I have looked all over. I would even take a datasheet. : :Thank you. :

Most likely a proprietary type number made for an oem. You won't be able to find one anywhere - unless the manufacturer of your equipment can help.

It is not proprietary.

How do you know that?

You've asked about a transistor that has a number that fits no standard, and yet does fit the sort of number you see on proprietary parts.

You want some, but can't find them.

You'll settle for an equivalent, but don't know any.

You haven't told us anything about why this transistor is so important to you.

That all adds up to a strong indication that it is a house number.

You know more about it than us, yet you are having trouble finding it. That's a good clue about something.

Yep, it is. It is a good clue that I am talking to a dumb kid who knows not much.

I know that it is not proprietary yet, you think that it is.

Grow up, get some modicum of intelligence and berate your parents for spoiling your sorry ass.

Now, run along.

I have to agree with Michael on this. Having had more than 50 years experience in electronics myself, and many of these specialising in component sourcing, your accusation against Michael is way off beam. In my experience if you can't find a single reference to a semiconductor part number on the WWW then it most likely does not exist or you have the part number wrong. And don't believe the Google search results which turn up the part number associated with a parts broker - it doesn't mean they have it or have even heard of it.

If you are sure that this part number is NOT proprietary then tell us how you know this. I certainly don't know of any surefire method of knowing for a fact that a part number is proprietary or not and I am sure you don't either.

If you are sure that I don't have a method then, there is no point in carrying this on.

I have been in this game for many years - over 50.

Well, bully for you. Your long experience doesn't appear to have engendered a spirit of being courteous enough to be more helpful with your information though, otherwise you would enlighten us as to HOW you know the device is "non-proprietary". Us old-timers are not averse to being educated.

I note that you still don't appear to have found a datasheet for your "non-proprietary" transistor - which you are so certain is such a device. I wonder what you plan to do next in order to obtain one?

Ross, You are a trouble-maker.

I came here asking for a transistor. You and a few others piped up saying that it is proprietary. I know that it is not proprietary and you demanded to know how I know that. Well, if you had more experience and knowledge in this field, you would know that, too.

Now, you can continue to demand this or that, make trouble and issue forth sarcasm. However, you won't get any education from me.

If you read from the beginning, I have been courteous right up to the point that you tuned up.

You assume much. You assume that I don't have the datasheet.

I just don't put up with your type.

Now, buzz off.

From your original message:

or equivalent. I only need one but would like to have some spares.

I have looked all over. I would even take a datasheet.

We never assumed, you told us.

You've fallen into the common error, that of people thinking that if they can throw around a degree other people will actually believe it. "I'm an electrical engineer, but I'm trying to fix my stereo and ...." The dot, dot, dot actually explains they don't know anything and it was all ploy of the clueless.

That may not be your case, but how are we supposed to know? All the time we see barely literate posts, people who expect us to know what they want when they don't throw in the details. So someone asks about how they can't use the XR2206 at 2MHz, and they get a long thread about it all, and then finally it's revealed that the original poster knows nothing and doesn't have the background to see beyond the XR2206 that they are familiar with because they've used it as an audio generator.

You post about a device that you don't know where to get, or find a datasheet, but that is identical to the beginner who posts the same sort of question.

You didn't even bother telling us that it was a Russian device, which probably wouldn't have helped your quest but at least gives your post context.

Without that context, it most definitely looks like a house number. And since you didn't deal with the real issue, but instead blustered about your experience, you made the whole thing worse. If you can't be bothered explaining how you need these devices that you know nothing about, then how is your post different from someone asking about where to get a tunnel diode? We've had those too over the years and all of them were from some beginner who found some old schematic on the internet and couldn't know that the schematic is old and that tunnel diodes had a very brief reign. There actually are legitimate reasons for someone needing a tunnel diode, not very many at this point but they do exist, but the poster who says they need it for the sweep trigger in their oscilliscope, or as some exotic pulse generator, I believe we have had people ask for those reasons, they would actually provide the need for that tunnel diode, because they know that otherwise the device is useless at this point.

Even now that we know it's a Russian device, one of your multi-posted messages in another newsgroup said something about that, the answer will still likely be a resounding nothing.

You're still the expert. How can someone have Russian devices but not have insight into where they might find replacements or datasheets? There are likely very few people reading this newsgroup that deals with Russian devices. You at least have the advantage of knowing what this device is used in (or we are led to assume that), that context should help you at least find replacement devices.

Find a company in Russia that sells transistors. Find a Russian newsgroup and ask there. Get a browser that deals with Cyrillic and start browsing. The same technics for finding information about exotic devices should apply here, with the caveat that the suitable webpages may be in Russian. Have you even done a websearch on the part number, just in case it actually gets a hit? If there are multiple hits, it most may be unrelated, but sometimes you actually are lucky.

Of course, we still don't actually know that it's Russian, all we know is that you claim it to be so. No context, no information about what equipment has these devices so we can't actually decide ourselves.

Post about the equipment, post about the package the device is in, post about the results you get when you test it with an ohmmeter, and then a general picture will build up that at least starts to allow suggestions of suitable substitutes.

The truth remains, either none of this is new to you, or it all is. Which means either you expect too much, or you are clueless.

Michael

You are one of those people that have multiple deficiencies. First one and foremost is that you are too stupid to realize that you are stupid. Second, you have a severe personality disorder that you are not aware of and when brought to your attention, will deny and shift the subject.

Also, you have no analytical skills whatsoever nor do you even begin to understand common logic, not Boolean indices.

You must think that the world is forever static and because, when I first started my quest, I did not have a datasheet. In your mind, I never will have one even though I have one right this moment.

You think that my posts are barely literate yet, cannot see your own illiteracy.

You are also intimidated by those who have credentials. You see son, it is all very obvious to those who have had the misfortune to deal with folks as yourself.

Most probably, you were spoiled by your parents and taught that you could do no wrong therefore, you have grown into a snot and will never be a person with backbone and strength of character until you have a severe epiphany in your life. You'd best hurry it up before you meet the wrong person.

Now, run along and call your mommy and daddy for consolation and assurance that you are a worthwhile person.

In my opinion, you are a lowly worm.

First lesson in getting a backbone and some character is to let this go. But, I know better.

Do you still want some SIV300004?
