Check the devices data sheets. Amp fixing groman Thanks for the advice – akltam Posted by akltam on January 05, at FETs are unipolar transistors as they involve single-carrier-type operation.

Does anyone has such experience with SJ and SK The bias currents you were using should be fine unless you have a way too high voltage across the transistors. Have you put a scope on the output to look oscillation datashdet a high DC offset?

I think that you don’t have it as with the Sj is not nedded Two Words posted by datashet on January 09, 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!

The gate resistor is ohm already.

Thanks for the advice – J. Santos on January 06, at I have my eyes without leaving the current meeting, the current then flutuated from 75 to as high as mA.

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 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! Also good for outputs for amps in the 25W size.

So you need a temperature compensation for the Sj,usualy a transistor multiplifier BE mouted in thermal contact with the output devices. 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.

What about the quality of these BUZ? Two pairs were used per channel. And would try the parallel cap as suggested. Alan djk is right!

I was suggested that some of these devices are dataseet unstable in the first hours. I leave it on for a while feeling OK. 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 you reply. 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!

Groman had a real good point about the bias voltage.

Then choose a final capacitor 1. And the Sj have it at mA. I rebuild the whole thing and this time I used around 50ma per pair, i. Catasheet more common, cheaper, drain to the case are of a vertical construction. How big are your gate resistors? And they will be usable if not better alternative! See my other reply! Many thanks for all of you who has helped.

Check for high frquency oscillations MHz range. They are very difficult to stabilize without some sort of bias servo. Yours information is very valuable. These are of the lateral type construction. THese are my favorites: I guess I will not use SJ for this circult. And also if current differ from high to low to high. They need to be as close as possible to the ouput transistors.

Phil Burning is typical unstable Circuit.

Jorge Santos Thermal Runaway – djk Farnell Electronics is datashwet distributor. 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. NT – akltam Do you have any 0.
