Hi,

the 2SC5200/2SA1943 are new Toshiba numbers, replacing the old numbers 2SC3281/2SA1302.

My data book says, they have the same characteristics.

So you could try to find the spice models for 2SC3281/2SA1302.

The AKSA FAQ also states that these pairs are identical, and they replaced the 2SC3281/2SA1302 with 2SC5200/2SA1943, when the latter went obsolete:
http://www.printedelectronics.com/faqs/faqs_aksa.html

BTW, these transistors are fine. I am using the 2SC5200/2SA1943 in one of my own designs, too.

regards,
Hartmut

Thanks, boraomega :)
Running these models. Screenshot:

An externally hosted image should be here but it was not working when we last tested it.


My spice test show some values that are Not reasonable to me.

At ... COLLECTOR-EMITTER 20 Volt and 1 Ampere:
2SC3281, VBE = 831mV
2SA1302, VBE = 631mV

I also have consulted the Datasheet diagrams concerning Voltage Base-Emitter. I can not find anything confirm such a difference.
I also ckecked out Orcad Spice library, but they use exactly the same model.
Shows that when one 'bad spice model' is around, it may turn up most everywhere. There are several known such cases of not correct models all over!


Here you can find the PDF Datasheets I have consulted:

hey!

Any comments and findings on this would be welcome.
:)

I will use these models to Evaluate a Power Amplifier schematic, found in internet.
So, of course, in order to get comparable results (with another known amplifier),
I surely want only as good Spice Models as possible:

2SC3281, 2SA1302

... who are said ( by Hugh 'AKSA' Dean ) to be comparable to
This Very Popular Output stage complementary pair:

2SC5200, 2SA1943


Thanks :cool: Lineup

Hello everybody,
I am looking for the schematic diagram for 2SC5200/2Sa1943 and they go with C2705/A1145.
Thank you so much!

No you are looking for the schematic of an amp! There is no 'schematic for 2SC5200/2Sa1943 and they go with C2705/A1145'. Those transistors are in an amp, and if you want to know how to use these transistors that depends on the amp schematic.
Please give type/brand etc of the amp....

Search on the forums here - I seem to remember that Andy_C has posted more accurate model(s) of the MJL1302/3281 that take care of some inaccuracies in the published OnSemi models.

Yea, his models are very good. He published models for 2sc4793/2sa1893 and 2sk1530/2sj201 transistors, also. Too bad he is banned from this forum, he is a great contributor and a very helpful person.

Fairchild has models on their website for their FJL4215/4315 transistors IIRC. These may be usable models for the Toshiba's.

>>[Andy_c] published models for 2sc4793/2sa1893 and 2sk1530/2sj201 transistors, also.

His website only offers the MJL3281/1302 set, unless I'm missing them.

Can anyone here tell me how to get subcircuit models to work using Notepad?

In LTspice, it is easier if you create a new symbol to go with the subcircuit model, e.g. for MOSFETs. The important thing is to get the order of the pins of the component right.

Your question covers a lot of ground. If you can be more specific about what you want to do, I'll try to help.

In the meantime, here is an example of a symbol and its subcircuit. To use, take off the .txt file extension, copy the .sub file into "C:\Program Files\LTC\LTspiceIV\lib\sub" and the .asy file into "C:\Program Files\LTC\LTspiceIV\lib\sym"
