FETs are unipolar transistors as they involve single-carrier-type operation.
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. 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!
I think the problem you have is thermal runaway as that the S only have a negative voltage quoeficient at 3 Amp. Go to this site: Santos on January 06, at Thermal Runaway posted by djk on January 06, at 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!
I set the bias current to 65 milliamp per pair. Have you put a voltmeter acros the bias network or from gate of J to gate of K and tracked that voltage with time? A resistor to Gate. Try up to R. Is there a schematic of the amp you’re using anywhere on the Web?
Check the devices data sheets. Thanks for you reply. Two pairs were used per channel. And also if current differ from high to low to high. Is this the case?
I suppose you have no oscilloscope. Have you put a scope on the output to look oscillation or a high DC offset? And they will be usable if not better alternative! Thanks for the advice posted by akltam dxtasheet January 06, at I think you know about those.
I am not sure, but I think they use the same die design for some dafasheet their devices as the orginal Hitachi parts. Hi Alan You’re right – those voltages should be be no problem. Sorry for my “english” Farnell Electronics is a distributor.
IRF datasheet groman Two Words – djk I have my eyes without leaving the current meeting, the current then flutuated from 75 to as high as mA.
Also good for outputs for amps in the 25W size. I don’t think it’s the transistor but a problem elsewhere.

Amp fixing groman Thanks for the advice – akltam They need to be as close as possible to the ouput transistors. Also the quality of these Dqtasheet See my other reply! 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.

I guess I will not use SJ for this circult. Surely there is no bias control circuitry as suggested to Santos and MLLoydl. After another hour, it was overheated and destroyed. Drain – Source Voltage Vdss. NT – akltam 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.
The bias currents datashdet were using should be fine unless you have a way too high 2sm1529 across the transistors. Yours information is very valuable.

And the Sj have it at mA. Groman had a real good point about the bias voltage. Then choose a final capacitor 1.
