Almost new Linear Fet

[6M9]

IXYS release the following device recently IXTK110N20L2
Its only available as a N channel device but it might be useful non the less
there is also much higher voltage devices available from the same family for those wanting to build a amp for electrostatic devices.

Perhaps papa could comment as to the usefulness of this device for audio

I have an Ixys part in the amplifier I am presenting at BAF 09.

usual pro et contra saving for later ..... or never .... or guessing game ?

[jacco vermeulen]

Yawza, a 1kW power device.

Speaking of Ixys: Did you ever measure any of their P-channel mosfets for linearity?

I got Ixys N-channel mosfets as surplus pretty cheap, and buying their p-channel counterparts to have complementary pairs would make most sense for me. It would be good to know that they don't have the same IRF linearity quirk.

Thank you very much Papa for the reply

this could be a very fine MOSFET for audio - see datasheet
http://ixdev.ixys.com/DataSheet/DS10...10N20L2%29.pdf
the not presently appropriate P-channel part is only a problem for beginners and inexperienced engineers, but not for advanced developers of audio amplifiers. Companies such as Quad (Super-ß and Current Dumping), SUMO (Circlotron / CSPP), NAD ("306", Quasi-complementary) and Creek (Totem Pole) has introduced already more as 10 years ago and demonstrated, that P-CH MOSFET and PNP transistors for output power stages are not necessary. The company "Aussie Amplifiers" (Amplifier Kits - Audio Amplifier Modules - MOSFET Amps) also work with only one genus MOSFETs according to the philosophy of Bengt Olsson (Electronics World:" Better Audio from non-complements? "Bengt Olsson Dec 1994 page 988)
Thus, P-Channel MOSFETs for audio amplifiers really have no justification in currently days.
In this context, I have create an detailed overview about a wide range of power amp concepts with only N-Channel MOSFETs in power output stages - about the URL

[Melon Head]

Yes I am a big fan of the quasi-complemetary output stage

tiefbassuebertr, the Ciss on your mosfet is sky-high. How would you get around it?

Mean you "burning amplifier festival 2009" or is BAF-09 already a new project?

my English is not good and my colloquial (conversational) English is even worse;
mean you what of this topology I would prefer?
