I don’t think it’s the transistor but a datasheeh elsewhere. Because these two terminals are normally connected to each other short-circuited internally, only three terminals appear in electrical dataasheet.

I rebuild the whole thing and this time I used around 50ma per pair, i. Thanks for the advice posted by J. FETs are unipolar transistors as they involve single-carrier-type operation. Produst description 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.

Thanks for the advice – J. Thermal Runaway posted by djk on January 06, at 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!

Gate threshold voltage Vgs th. I am not sure, but I think they use the same die design for some of their devices as the orginal Hitachi parts.

So you need a temperature compensation for the Sj,usualy a transistor multiplifier BE mouted in thermal contact with the output devices. Two Words posted by djk on January 09, at And also if current differ from high to low to high.

I have my eyes without leaving the current meeting, s2k1529 current then flutuated from 75 to as high as mA. Drain – Source Voltage Vdss. Is there a schematic datasheet the amp you’re using anywhere on the Web? Farnell Electronics is a distributor.

Is this the case? Any experience on 2SJ and 2SK? Groman had a real good point about the bias voltage. THese are my favorites: Many thanks for all of you who has helped. The MOSFET is by 2zk1529 the most common transistor in both digital and analog circuits, though the bipolar junction transistor was at one time much more common. A resistor to Gate. Surely there is no bias control circuitry as suggested to Santos and Vatasheet.

They need to be as close as possible to the ouput transistors. Try up to R.

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! Go to this site: I set the bias current to 65 milliamp per pair.


I suppose you have no oscilloscope. Audio Asylum Thread Printer Get a view of an entire thread on one page. Burning is typical unstable Circuit. Alan I don’t think the problem is with the transistors. They are very difficult to stabilize without some sort of bias servo.

Also good for outputs for amps in the 25W size. Do you have any 0. I think the problem you have is thermal runaway as that the S only have a negative voltage quoeficient at 3 Amp.

I 2s1529 you know about those. Check the devices data sheets. Posted by akltam on January 05, at I guess I will not use SJ for this datawheet. The gate datashee is ohm already. The bias currents you were using should be fine unless you have a way too high voltage across the transistors. Have you put a voltmeter acros the bias network or from gate of J to gate of K and tracked that voltage with time? Jorge Santos Thermal Runaway – djk NT – akltam Yours information is very valuable.

There is a Zobel already. Check for high frquency oscillations MHz range. And the Sj have it at mA.

I think that you don’t have it as with the Sj is not nedded Then choose a final capacitor 1.
