From the circuit and to gate, placed close to the Gate Value can between about ohms By the way, try to keep the distance between circuit and MOSFETs short as possible! Thanks for the advice – J.

Most other devices for example HexFETs don’t have a zero tempco until the drain current reaches the several amps region – so you’d need daasheet bias control circuit! I think you know about those. Sorry for my “english” Because these two terminals are normally connected to each other short-circuited internally, only three terminals appear in electrical diagrams. Burning is typical unstable Circuit. Put an small plastic capacitor parallell over feedback resistor goes from output to inputstage pF or pF See if it gets better if so you have found that amp was unstable.

Xatasheet think that you don’t have it as with the Sj is not nedded Vatasheet you have any 0. Is this the case? Check the devices data sheets.

Two pairs were used per channel. It shares with the IGBT an isolated gate that makes it easy to drive. The gate resistor is ohm already.

Jorge Santos Thermal Runaway – djk They are very difficult to stabilize without some sort of bias servo. Have you put a scope on the output to look oscillation or a high DC offset? Groman had a real good point about the bias voltage. Drain – Source Voltage Vdss. Alan djk is right!

NT – akltam There is a Zobel already. These are of the lateral type construction. Go to this site: I have my eyes without leaving the current meeting, the current then flutuated from 75 to as high as mA.

I don’t think it’s the transistor but a problem elsewhere. I was suggested that some of these devices are pretty unstable in the first 2sk529. And also if current differ from high to low to high. I guess I will not use SJ for this circult.

Amp fixing groman Thanks for the advice – akltam What about the quality of these BUZ? Any experience on 2SJ and 2SK? Ddatasheet rebuild the whole thing and this time I used around 50ma per pair, i.

Posted by akltam on January 05, at Santos on January 06, at The bias currents you were using should be fine unless you have a way too high voltage across the transistors. Hi Alan You’re right – those voltages should be be no problem. Does anyone has such experience with SJ and SK I set the bias current to 65 milliamp per pair.


See my other reply! Alan I don’t think the problem is with the transistors. Two Words posted by djk on January 09, at Thanks for you reply. I suppose you have no oscilloscope. In fact that resistor together with the input capacitance messured in pF, see datasheet, forms a RC-lowpassfilter, that makes the fast MOSFETs somewhat slower, that gives a lower Open Loop Bandwidth, and so it can make the amp more stable!

Have you put a voltmeter acros the bias network or from gate of J to gate of K and tracked that voltage with time? Gate threshold voltage Vgs th.

Farnell Electronics is a distributor. And the Sj have it at mA. Yours information is very valuable. I had a similar problem a month ago and it drove me crazy. Produst description The Field-Effect Transistor 2ak1529 is a transistor that uses an electric field to control the shape and hence the conductivity of a channel of one type of charge carrier in a semiconductor material. How big are your gate resistors?

So you need a temperature compensation for the Sj,usualy a transistor multiplifier BE mouted in thermal contact with the output devices.
