Hi

Does anyone out there have the datasheets for the Lovoltech LD1107N JFETs?

Thanks,
Niels Christian

I have the pdf, but its size exceeds the attachment limit.

How would you like it?

Really?! That's great news. Can you email it to me? My email address is ncbuhl@hotmail.com.

Thanks a lot

So.... Have you thought of an application for such a device?

Has an interesting Drain resistance characteristic.

Thanks for the specs. I'm doing my bachelor's thesis on a current-driven power stage for an audio amplifier.

I'm considering using a JFET topology to avoid the need for extra diodes due to the body diode of regular MOSFETs. My supervisor had a bunch of the Lovoltech JFETs in his drawer but no datasheet, hence my request.

Examining the datasheet I think the perspective is promising, although the maximum V(DS) is quite low and limits the output power. But for my project it might be okay, since it's just a proof-of-concept project. The FET can withstand a high drain current, which is what I need for my design. I'm gonna have to give some more thought.

hi all,

quite interesting device: low voltage and decent amount of current.

when going to lovoltech.com i cannot really see a way to obtasin parts from them anymore. does anyone have an idea what happend to their production of power jfets?

thx

Hi again,

Does anyone have a SPICE model of this transistor??

Thanks
