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 s2k1529 charge carrier in a semiconductor material. Surely there is no bias control circuitry as suggested to Santos and MLLoydl. I don’t think it’s the transistor but a problem elsewhere. Any comment on the SJ I have datashet eyes without leaving the current meeting, the current then flutuated from 75 to as high as mA.

Yours information is very valuable.

I leave it on for a while feeling OK. I think the problem you have is thermal runaway as that the S only have a negative voltage quoeficient at 3 Amp. What about the quality of these BUZ? I think you know about those. Posted by akltam on January 05, at A resistor to Gate. IRF datasheet groman Two Words – djk Groman had a real good point about the bias voltage.

datashheet Sorry for my “english” FETs are unipolar transistors as they involve single-carrier-type operation. Amp fixing groman Thanks for the advice – akltam Also good for outputs for amps in the 25W size.


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. Then choose a final capacitor 1.

Jorge Santos Thermal Runaway – djk The more common, cheaper, drain to the case are of a vertical construction. Burning is typical unstable Circuit. Is there a schematic of the amp you’re using anywhere on the Web?

It shares with the IGBT an isolated gate that makes it easy to drive. Thanks for the advice – J. NT – akltam Two Words posted by djk on January 09, at Santos on January 06, at I have built similar power amps with the same circuit with SJ but with satisfactory results. I had a similar problem a month ago and it drove me crazy.

Is this the case? After another hour, it was overheated and destroyed. These are of the lateral type construction. Any experience on datawheet and 2SK? Thanks for the advice posted by J. I set the bias current to 65 milliamp per pair. The bias currents you were using should be fine unless you have a way too high voltage across the transistors.

I am not sure, but I think they use the same die design for some of their devices as the orginal Hitachi parts. I think that you don’t have it as with datasbeet Sj is not nedded So you need a temperature compensation for the Sj,usualy a transistor multiplifier BE mouted in thermal contact with the output devices.


And they will be usable if not better alternative! 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 are very difficult to stabilize without some sort of 2ek1529 servo. 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 s2k1529 as possible!

That has 2sk5129 me to believe that the Mosfet itself could be the cause. Do you have any 0. Many thanks for all of you who has helped. Have you put a scope on the output to look oscillation or a high DC offset?

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.

Check for high frquency oscillations MHz range. 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. Alan djk is right!

There is a Zobel already. Try up to R.
