Toshiba monolithic dual transistors: SA1349/SC3381
 
Thought it might be more appropriate to re-post here (as compared to the Solid State New Law thread). Please don't go and buy all the stock from Reichelt before I have my go:)

Found SA1349/SC3381 in Borbely article. Seem to be 80 V monolithic dual transistors with reasonable C_cb (4.2 for the SA, nothing quoted in Tower's for the SC, neither is f_T). Are still available from Reichelt at less than a each. Unfortunately, no data sheet and SPICE models at Toshiba or the web.

ARRRRRRRRGGGGGHHHHHH!
 
Eric,

You guys are trying to get not to read this forum anymore aren't
you.......

If I were moderator I would ban you for a week. If you had asked how big a heat sink to use with....... I would have banned you forever. USE THE SEARCH ENGINE ON THE FORUM PEOPLE! PLEASE!!!

How big of a heatsink does my STENDEC need?

Jocko

mrfeedback 2nd April 2002 05:00 PM

That depends how much hot air your want to make.

The other Eric.

Jocko Homo 2nd April 2002 05:31 PM

Almost as much as Hairy........[joke]

"official" models
 
Now I know why Jocko calls you by the funny name...

I did do a worldwide search for A1349/C3381. Tells you something about the quality of the search engine if it is not able to find a string in a text file...

But, being a frequent reader of your posts, I tried your link before posting. The header of the file reads:
* Library of Japanese Bipolar Transistor Models

* Copyright OrCAD, Inc. 1998 All Rights Reserved.

*$


Good news: whoever did the modelling had the data sheets.

Bad news: This is not the official model endorsed by the manufacturer (if there is any). This model was apperently synthesized by trying to duplicate the typical behavior in the data sheets. Knowing other Toshiba small signal transistor data sheets, not much information about dynamic behavior is given.
Maybe I should have stated more clearly that I was looking for official models.

That's alot.

Eric.

Spice
 
I am sorry that the models were not use useful for you. It appears
that you are up Spice creek without a paddle. Maybe someone else can help.... perhaps Sonny. I am so sorry as not to be able to get you what you needed. By the way, the official name is Jocko and what funny name does he call me?

Ok, edited that typo into Jocko. Well, don't tell me you haven't seen those references to Hairy Holler...

Have a nice day, anyway!

Eric

Jocko Homo 2nd April 2002 06:51 PM

Don't worry......he knows. His sense of humour is just as sick as mine. But Herr Eric, you haven't caught all the jokes yet. Keep looking, they are right in front of you (and everyone else) for one and all to see.

Keep on hollerin' Hairy.

Joke-o
