Datasheets for Lovoltech LD1107N

[ncbuhl]

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.

ncbuhl - can you mail me that file ;

I'll split it and attach here

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

letsfetz, at least the ld1014d was discontinued. Deepsurplus bought some of the last
ones available.

I believe I do... Have to wait till I get home though...

I speculate that they inherited them through the acquisition of
the assets of another company. I think I bought about half their
inventory and possibly some of the remainder was tossed.

In any case, I think you have to look to SemiSouth now for new power JFETs.

Well, regarding the models, I seem to have lost them. I had a disc crash last summer and I can't seem to find 'em anywhere now 🙁 I have given them to some of the members of this forum so, some one may step up and offer to give them back to us 😱 You may be able to do a search and find the thread where I offered them and who requested I send them?
I had very good results just modifying the standard jfet model for the LU1014D, the 2sk170 for instance, with data sheet info and in circuit measurements. As I remember the Vth was 1.15, Beta was 28, Lambda is important but 😕

As I understand the Lovotech story they did not even have their own production facilities. They went to an outside foundry. Then some deal took place where they changed their name to Qspeed...
