Hi

On www.onsemi.com you can finde models of many semiconductors. I know they have mje15030/31 (i use them mje15032/33 or for drivers)

Good luck

\Jens

My "model" is in my headKilowatt said:Does someone have spice models for these transistors? CircuitMaker doesn't.

Thanks.

Is THAT enough

MODEL is a Brain Combination of

the data-SPECIFICATION of this excellent

MOTOROLA semiconductor

I have to LAUGH at "your" models

but as a good laugh

Other models I like to spend time with

Has to be for REAL and be able to LAUGH a lot

Cheers

How many of those,Kilowatt said:Well don't worry, the parts that are on their way UPS from Allied are very real, and so are the PCB's. The amp, when completed, will be too, and they should sound very nice (improved ESP p3a, Tangband 4" midwoofers).

do you use?

My designs are for REAL like yours are.

Glad to HEAR what you say!

Did you HEAR ME

the VIKING with the BLONDES of his country

Xovers at 250Hz and 6.2kHz (and yes, those Tangbands can go that high, very nicely).

Are there any spice models circulating for the popular Toshiba JFETs (2sk170, 2sk389, 2sj74, etc) ?

Or their BJTs for that matter?

Don't underestimate the power of SPICE models -- properly done they can capture subtlties that you can't begin to imagine from a data sheet.

For example, look at the MJ15003 model above. Although it is itslef somewhat crude it tells you something that the data sheet can't -- that the distributed base resistance is significant enough to make it worth modeling the device as a composite of two idealized BJTs, with internal base resistance dividing them. The base spreading resistance isn't even mentioned in the data sheet, and even if it were, it would be very difficult to estimate how it interacts with the various capacitances.

In fact, the silly data sheet

http://www.onsemi.com/pub/Collateral/MJ15003-D.PDF

doesn't even mention Ft or any junction capacitances. So you'd be pretty lost trying to design anything that needed speed, without most likely overdoing it.

Thank you, HH.

I have found spice semiconductor models available on the web from

Philips Semiconductors, on semiconductors, IRF, Zetex, and Vishay

Some manufacturers of tantalum and ceramic capacitors (Kemet, AVX, probably others) have models of sorts for their caps, one look at the results of those and you probably decide to move on ... but potentially instructive nevertheless.

I think Rohm will email spice models to you; I haven't tried that yet.

It isn't evident from Toshiba's site how to get them ...

anyway ...

It might be useful to exchange information about model sources.

So here's a call for some information exchange:

Which other semiconductor manufacturers have models easily available on the web?

What other sources do people use?

This thread is kindof old but I am wondering if I could get SPICE models (LTSPICE/SWCADIII) for motorola MJE2021 and MJE2011. I need these models for a circuit I want to test out at http://www.4qdtec.com/pwramp.html . I am a fan of symetrical amplifier designs because they seem more prone to amplify each end of the wave equally. Also, if you have any designs of better cicuits that have lower component counts, PLEASE let me know .
