Hi guys,
Anyone having information about high voltage JFET's ..probably which can support voltages of magnitude 150V [VDS]
thanks in advance...

Toshiba's highest voltage JFET only 100V¡A like 2SK373 .
Thanks DJK & MTLIN for the great links........
Greg,
yeah you are a great mindreader....yes i do need complementary , but if they are not available than i would narrow my search to P-channel HV JFETS only........
Dimitri.....
why are you scratching you head, dont you know the meaning of being a symmetrical implementation in design, oh i mean to say the symmetric design or you dont even understand what is the meaning of symmetry.......I donot know russian..but my father know the russian very well because he is in Vladivostok in Siberia.....

am I? 😕why are you scratching you head
should I answer?you dont even understand what is the meaning of symmetry

Now how about some high current / high power JFETs?
I looked on the net for high current jfets, but couldn't find any.
Do you have a stash Nelson? 😀
As far as I know, only small-signal JFETs have ever been made; a fact that has, I'm sure, annoyed many FET adherents. Depletion mode MOSFETs are similar, but not exactly abundant either.vdi_nenna said:I looked on the net for high current jfets, but couldn't find any...

50A but only 24V 🙁

That's strange. They clearly call them JFETs, but the specs look wrong: They have high transconductance, high input capacitance, low Rdson and there's an enhancement mode one listed, which I didn't think was possible for JFETs.dimitri said:

Gate Threshold Voltage for enhanced is positive 0.4V, for depletion is negative -3V, why not possible?

Wow, thanks Mr. Evil!
You will recall that in the 70's Yamaha marketed an amp
with power JFETs.
Thse look very interesting. I'll have to fire up the liquid
nitrogen submersion sink.

JFETs have a PN junction between gate and source, so current flows into the gate if they are forward biased, which is not good. Looking at the datasheets, it seems that their enhancement JFETs are designed to withstand a high gate current, but I'm not sure how they are useful comared to MOSFETs.dimitri said:http://www.lovoltech.com/Technology/Technology.htm

You mean thanks dimitri - I posted nothing🙂Nelson Pass said:Wow, thanks Mr. Evil!
