UJT in any Simulator?

Hello experts!

In which software I can find UJT (for example, 2N2646)?
I am using Proteus and Multisim, but their libraries don't contain the UJT. They have PUT. I want UJT.
If is there any simulator other than Orcad or if it is in Orcad then please tell me.

Thank you very much.

Regards,
Princess

I use the free simulator LTspice from Linear Technology.

There is a Yahoo group for it
**broken link removed**

So perhaps you may like asking for the UJT in the LTspice group too. Its members are also friendly as here.

@keith1200rs

what is this code about? What to do with that? And how to use it ?

Thank you very much.

@KerimF
Thank you very much for you reply. Do you think LTSpice is a good simulator and has good library having most of the most commonly used components?
Thank you again

Before I installed LTspice on my PC, I had to test everything I design (analog and digital) by using my digital storage oscilloscope.

It happens that LTspice gives me what my DSO does and a lot more (even the trace window looks as being of a scope), also for analog and digital circuits (separated or combined). It is for analyzing circuits from very simple ones to complex and professional ones (with different types of analysis, including the transient one in the real time).

About the component’s models, I don’t know yet a component that I may need in my designs and couldn’t find its model for LTspice.

For instance, the model file 2n2646.sub which is referred by keith1200rs could be used on LTspice.

And as I mentioned earlier, the Yahoo group of LTspice is a very good place to ask anything (when searching doesn’t help) about how to run the program and get the models. There is also a big archive (files section) in this group about tutorials, examples, libraries... etc.

Are you also registered to the yahoo group too?

Yes, I am... also as Kerim
