Produst description The Field-Effect Transistor FET is a transistor that uses an electric field to control datasheett shape and hence the conductivity of a channel of one type of charge carrier in a semiconductor material. Really lots of thanks here. Thermal Runaway posted by djk on January 06, at Thanks for the advice – J. I have built similar power amps with the same circuit with SJ but with satisfactory results.

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! Is this the case? Audio Asylum Thread Printer Get a view of an entire thread on one page.

Also good for outputs for amps in the 25W datazheet. I leave it on for a while feeling OK.

Go to this site: Datashet also if current differ from high to low to high. THese are my favorites: Jorge Santos Thermal Runaway – djk I think that you don’t have it as with the Sj is not nedded Hi Alan You’re right – those voltages should be be no problem. Any experience on 2SJ and 2SK?

I set the bias current to 65 milliamp per pair. So you need a temperature compensation for the Sj,usualy a transistor multiplifier BE mouted in thermal contact with the output devices.

I had a similar problem a month ago and it drove me crazy. Two Words posted by djk on January 09, at Groman had a real good point about the bias voltage.

And they will be usable if not better alternative! Farnell Electronics is a distributor.

Drain – Source Voltage Vdss. Surely there is no bias control circuitry as suggested to Santos and MLLoydl. They are very difficult to stabilize without some 2sm1529 of bias servo.

After another hour, it was overheated and destroyed. What about the quality of these BUZ? There is a Zobel already. Compared to the other power semiconductor devices, for example IGBT, Thyristor, its main advantages are high commutation speed and good efficiency at low voltages.

I suppose you have no oscilloscope. Phil Burning is typical unstable Circuit. FETs are unipolar transistors as they involve single-carrier-type operation.

A resistor to Gate. Have you put a scope on the output to look oscillation or a high DC offset? And the Sj have it at mA.

Yours information is very valuable. Sorry for my “english” I rebuild the whole thing and this time I used around 50ma per pair, i.

The more common, cheaper, drain to the case are of a vertical construction. Thanks for the advice posted by J.

datasneet They need to be as close as possible to the ouput transistors. I have my eyes without leaving the current meeting, the current then flutuated from 75 to as high as mA.

Because these two terminals are normally connected to each other short-circuited internally, only three terminals appear in electrical diagrams. 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.

From the circuit and to gate, placed close to the Gate Value can between about ohms 2sk1592 the way, try to keep the distance between circuit and MOSFETs short as possible!

Thanks for you reply. The bias currents you were using should be fine unless you have a way too high voltage across the transistors. How big are your gate resistors?
