Spice models

[JoeBob]

Well, I recently discovered spice. It sure is wonderfull. But I can't find any spice models for toshiba 2SC2240 and 2SA970 BJTs, can anyone send me them? In case it matters, I'm using LT's free spice simulator.

Add them to standard.bjt and .jft

Good luck Sonny. I got my but chewed because the last models I offered were not the "official" models! By the way people, some of the Spice models from the vendors are not perfect. That is why people measure things after modeling them.

Hi Harry

Have you read the "disclaimer" from any vendor...

I think it says it all.

By the way i am going to build an preamp/amp next month i think .. When i have the money for PCB's.

You are right about testing after modeling. There could be a lot of things wrong with you sim... Temperature, perfect supply rails etc.... Still you can see how far of track you are! not by nanometers but millimeters.

[JoeBob]

Don't worry, I wouldn't "chew" anyone. Even if they're off, it's probably better to use them, then a different transistor model.

And simulating it is just supposed to get an idea if it'd work, I know the real thing is gonna be really different...

Oh, and thanks by the way .

Spice models..............

If I knew you were going to model those things, I wouldn't have sent them to you. [joke]

Just hook 'em up.

[JoeBob]

Oh, I will. But I was just playing around with spice, and thought I might as well use the right ones.

Spice is cool and all, but I still think there's no substitute to actually building the circuit. Plus, probing with a real multimeter is so much more fun .

PCBs

Sonny,

I can provide two links for companies that will make double sided PCBs at 50€ per 160x100 mm² card (if you can wait three working weeks). Turns out I usually am not patient enough and make them at home...

One is www.pcb-pool.de.

I'd have to search for the other one, nice thing being it will contain stop lacquer.

Hi Eric

I can see this is the same price as the one i got from ELPRINT in denmark. 4 boards (100x160mm) ~ 1800 - 2500 dkr. depending on number of tools,density thickness of tracks.
I use them already at my work.
The board are going to be fullsize like A4 paper.

But thanks for the link.

Thanks for the jfet spice models.
But would anyone happen to have any mosfet spice models. Like the Hitachi mosfets-2sj162 and 2sk1058. I went to the Hitachi web site but I didn't see anything about spice models.

 

[JoeBob]

What I want to know, is where do you guys get your models? I've also been looking for ZTX450 and ZTX550 models everywhere with no luck.

http://www.zetex.com/3.0/spice/zmodels.lib

10 minutes, started on www.altavista.com search for Zetex. Seach for spice on zetex site got menu with Applications and then menu with Spice models. Where did you look?

H.H.

 

[JoeBob]

I searched google for ZTX450 and spice, found nothing. I tried searching the Zetex website, yet got errors when I pressed the search button. I also tried another search engine and the only hits I got were "Buy SPICE model library for $XX USD here!".

Thanks though Harry.

Any HELP for me Harry?

Thank you very MUCH, HarryHaller.

JoeBob,

I am in the same situation. I had my wife call Toshiba in Japan (she is Japanese) and ask for thier SPICE models. They would supply them to me, ONLY if I promised not to share them. I wouldn't and they didn't.

I have to belive that The Japanese use SPICE and they must have models for thier own devices, but I couldn't get my hands on any of them.

To any Japanese people out there reading this forum: HELP!

One possible solution: IF you can find a cross reference of Japanese to American (western) standard part numbers. EG: a 2SC2240 = a 2Nxxxx. (or MJxxxx, TIPxx, etc) Then use the western model for your simulation. Any reliable cross reference should be close enough to use for a SPICE simulation.

You can get the Specs (in .pdf files form) for all the Japanese part numbers off the Toshiba web site.

Another possible solution: SPICE, Practical Device Modeling by Ron Kielkowski. Make sure you ge a copy with the diskette. Then create your own devices models.

Good Luck and let me know if you get a solution.
