I also tried searching for it, and you were right, it was the first one on the search list.. sorry about that.. but uhhm, how do you convert that information to a spice model?

I need to simulate a circuit involving a dual npn transistor,
specifically 2N2920 transistor,.. Well I can't find a model here...
Could you help me out... Maybe i didn't search enough... Do you guys
know where i can find that transistor? or any transistor model similar
to 2N2920? Thanks..
Maybe you didn't search enough. The first hit I get from Google leads
to:
Scroll down. The model looks very basic to me, but may be enough.
Hello,
This model is only useful, if you are interested in DC or very low frequency operation, because the only daynamic parameter included is Tf. Cje, Cjc and Tr are required to get reasonable results at higher frequencies or if the transistor saturates (Tr). The LTspice help file lists the parameters for a BJT model. In many cases the defaults are ok, but the ones I listed above are required. Google for WkwMmodels.pdf for good information on device modeling. It explains how to determine device parameters from typical datasheet information.
