SPICE models for MJ15003/4, MJE15030/31

[Kilowatt]

Does someone have spice models for these transistors? CircuitMaker doesn't.

Thanks.

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

Hi
If I recall correctly, I think Harry posted the MJ15003 here before, try the search. That's how I got mine into the sim model files.

Thank you.

Thanks.

My "model" is in my head
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
is said to make one's life longer

Other models I like to spend time with
Has to be for REAL and be able to LAUGH a lot
Cheers

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).

How many of those,
do you use?

My designs are for REAL like yours are.
Glad to HEAR what you say!
Did you HEAR ME

Two Leach amps (120W each) each driving 2 x Sony Xplod 12" subs (but I'm going to get better subs); two improved p3a based amps (70W each, or as needed), each driving 2 x Tangband 4" W4-656S midwooders; four 20W DoZ amps each driving an Audax TM025F1 1" tweeter in dipole arrangement, or two beefed up DoZ amps each driving 1 or 2 tweeters, I haven't decided for sure yet.

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.
