Tekko · 27th June 2011, 03:14 AM

Can anyone help me out with getting a ltspice model for the 2SK332F dual jfet ?

Much appreciated if someone has a model for this jfet or can tell me a suitable substitute among the 2Nxxxx ones in LTspice.

That seem to be working, i pasted it into the standard.jft and it popped up in the "pick a new jfet" list. Thx

Now im just gonna add the MJE340/350 and the MJL4281A/4302A and i'll be done.

MJL4281A/MJL4302A is probably almost the same as MJL3281A/MJL1302A
I use andy_c spice models
