anyone know the best way to model a c945 and a ksd1616 transistor in pspice? also i am trying to model a linkcom ldt0297 transformer which i do not have any specs on. It has 5 pins on the primary and 2 in the secondary so I am thinking it is center fed on the primary. I use k-linear to model that in pspice. Is that the right approach?

You can use model editor to model the transistor. You can directly input the various characteristics waveform from data sheet (in form of XY table) and tool would extract the various SPICE model parameter.
About Transformer- Yes. Your approach is just right. K_linear would not model non linear (hysteresis etc) effect of magnetic core.

If it were me, I'd be looking for some other vendor's
SPICE library for a similar topology xfmr, and then
re-parameterize it. You may care about more than
simple leakage and mutual inductances - certainly
a pulse application will care about interwinding C
and so on.

Linkcom's Taiwan web site shows no such part number
which may account for your problems there. Either
this is obsolete, or there's another Linkcom who uses
similar numbering somewhere else.
