After another hour, it was overheated and destroyed. Alan djk is right! See my other reply! Go to this site: Check the devices data sheets. The bias currents you were using should be fine unless you have a way too high voltage across the transistors. Try up to R. I had a similar problem a month ago and it drove me crazy. I think that you don’t have it as with the Sj is not nedded I leave it on for a while feeling OK.

Burning is typical unstable Circuit. Posted by akltam on January 05, at Yours information is very valuable. Sorry for my “english” Really lots of thanks here. I think the problem you have is thermal runaway as that the S only have a negative voltage quoeficient at 3 Amp. Alan I xatasheet think the problem is with the transistors. Hi Alan You’re right – those voltages should be be no problem.


I guess I will not use SJ for this circult. Thanks for you 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.

Any comment on the SJ I don’t think it’s the transistor but a problem elsewhere. Groman had a real good point about the bias voltage. They are very difficult to stabilize without some sort of bias servo. Have you put a scope on the output to datasbeet oscillation or a high DC offset?

Two pairs were used per channel. I suppose you have datassheet oscilloscope. I have built similar power amps with the same circuit with SJ but with satisfactory results. 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 datassheet circuit!

I rebuild the whole thing and this time I used around 50ma per pair, i. Also the quality of these BUZ?

Then choose a final capacitor 1. Is this the case?

Do you have any 0. Have you put a voltmeter acros the bias network or from gate of J to gate of K and tracked that voltage with time? Drain – Source Voltage Vdss. That has led me to believe that the Mosfet itself could be the cause. Any experience on 2SJ and 2SK?

Also good for outputs for amps in daasheet 25W size. Compared to the other power semiconductor devices, for example IGBT, Thyristor, its main advantages are high commutation speed and good efficiency at low voltages. They need to be as close as possible to the ouput transistors.

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.

Phil Burning is typical unstable Circuit.

IRF datasheet groman Two Adtasheet – djk Is there a schematic of the amp you’re using anywhere on the Web? Does anyone has such experience with SJ and SK Produst description The Field-Effect Transistor FET is a transistor that uses an dxtasheet field to control the shape and hence the conductivity of a channel of one type of charge carrier in a semiconductor material.

The more common, cheaper, drain to the case are of a vertical construction.

Thermal Runaway posted by djk on January 06, at FETs are unipolar transistors as they involve single-carrier-type operation. A resistor to Gate. Surely there is no bias control circuitry as suggested to Santos and MLLoydl. I think you know about those. These are of the lateral type construction.
