The MOSFET is by far the most common transistor in both digital and analog circuits, though the bipolar junction transistor was at one time much more common.
Really lots of thanks here. The Field-Effect Transistor FET 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. Because these two terminals are normally connected to each other short-circuited internally, only three terminals appear in electrical diagrams.
The gate resistor is ohm already.

I don’t think it’s the transistor but a problem elsewhere. 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.
Any comment on the SJ I have built similar power amps with the same circuit with SJ but with satisfactory results. NT – akltam THese are my favorites: I leave it on for a while feeling OK. Compared to the other power semiconductor devices, for example IGBT, Thyristor, its main advantages are high commutation speed and good efficiency at low voltages.
FETs are unipolar transistors as they involve single-carrier-type operation. Jorge Santos Thermal Runaway – djk Santos on January 06, at And they will be 2sm1529 if not better alternative!

There is a Zobel already. Go to this site: Thanks for the advice – J. Two Words posted by djk on January 09, at I think that you don’t have it as with the Sj is not nedded Alan djk is right! Thermal Runaway posted by djk on January 06, at I think the problem you have is thermal runaway as that the Adtasheet only have a negative voltage quoeficient at 3 Amp.
How big are your gate resistors? I think you know about those.
Try up to R. Groman had a real good point about the bias voltage. The bias currents you were using should be fine unless you have a way too high voltage across the transistors. 2sk1592 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!
Thanks for the advice posted by J.

Posted by akltam on January 05, at And would try the parallel cap as suggested. And also if current differ from high to low to high. And the Sj have it at mA. IRF datasheet groman Two Words – djk Is this darasheet case?

I guess I will not use SJ datasheey this circult. Check the devices data sheets. Check for high frquency oscillations MHz range. That has led me to believe that the Mosfet itself could be the cause. Drain – Source Voltage Vdss. 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!
