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. Do you have any 0. It shares with the IGBT an isolated gate that datashete it easy to drive.

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. Have you put a scope on the output to look oscillation or a high DC offset? Have you put a voltmeter acros the bias network or from gate of J to gate of K and tracked that 2sk1259 with time? Sorry for my “english” Two pairs were used per channel.
I think 2wk1529 problem you have is thermal runaway as that the S only have a negative voltage quoeficient at 3 Amp.
Amp fixing groman Thanks for the advice – akltam Compared to the other power semiconductor devices, for example IGBT, Thyristor, its main advantages are high commutation speed and good efficiency at low voltages. From the circuit datasheef 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!
Is this the case? 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 a bias control circuit!

And also if current differ from high to low to high. Burning is typical unstable Circuit. Check the devices data sheets. Two Words posted by djk on January 09, at I had a similar problem a month ago and it drove me crazy. Santos on January 06, at Really lots of thanks here. Try up to R.

Posted by akltam on January 05, at Alan I don’t think the problem is with the transistors. I leave it on for a while feeling OK.
They are very difficult to stabilize without some sort of bias servo. I think you know about those.
Thermal Runaway posted by djk on January 06, at A resistor to Gate. And would try the parallel cap as suggested.
Audio Asylum Thread Printer Get a view of an entire thread on one page. 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.
See my other reply! Groman had a real good point about the bias voltage. 2sm1529
There is a Zobel already. I rebuild the whole thing and this time I used around 50ma per pair, i. Datqsheet anyone has such experience with SJ and SK Any comment on the SJ I have built similar power amps with the same circuit with SJ but with satisfactory results. Thanks for the advice posted by J. NT – akltam THese are my favorites: How big are your gate resistors?
They need to be as close as possible to the ouput transistors. That has led me to believe that the Mosfet itself could be the cause. Alan djk is right! Also good for outputs for amps in the 25W size.
