Hi
does anybody have a PSpice
or any spice model for
Power JFET
LD1014
LU1014
by Lovoltech
?
Thanks...

Anybody know of distributors or does Lovoltech they fill small orders direct?

I'd be interested in trying a balanced amp runningthrough the linear curve region.

Does anyone know how to find a couple of LU1014 for a Zen V9?
To ship it to France?

Thanks for help

Zoran, and everyone interested... These were given to me by QSpeed

Enjoy

Hello,

I'm digging up this old thread, because I'm having trouble using this model in Multisim. As can be seen from the graphic, it's rather nonsense. Any idea what might be going wrong?

When importing the model, Multisim asks to connect pins 1/2/3 to gate, source and drain. I tried all combinations, but the result always looked the same.

Thanks, Volker

I think as I recall, I could get good results modifying a 2sk170 model

if you can beleve that. Some of their numbers seemed a little off to me. Like for instance I think their Vgsth number is 1.8? I think it should be 1.15. I don't remember exactly but the "Beta"(transconductance) needs to be changed to about 28. And Lambda about .9. Give that a try. All other parameters were strait off the data sheet

Thanks, I'll give that a try!

Could you could maybe post your corrected model as well? I'll see where I'm getting at, but I'm relatively new to Spice, so success isn't guaranteed
