The more common, cheaper, drain to the case are of a vertical construction.
Because these two terminals are normally connected to each other short-circuited internally, only three terminals appear in electrical diagrams. IRF datasheet groman Two Words – djk I think that you don’t have it as with the Sj is not nedded Any comment on the SJ Thanks for the advice posted by akltam on January 06, at Thanks for dattasheet reply. Have you put a scope on the output to look oscillation or a high 2sj1529 offset?
Hi Alan You’re right – those voltages should be be no problem. Compared to the other power semiconductor devices, for example IGBT, Thyristor, its main advantages are high commutation speed and good efficiency at low voltages.

What about the quality of these BUZ? Is this the case? Many thanks for all of you who has helped. Sorry for my “english” 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.

See my other reply! And also if current differ from high to low to high. Santos on January 06, at Try up to R. They need to be as close as possible to the ouput transistors.
It shares with the IGBT an isolated 2si1529 that makes it easy to drive. Surely there is no bias control circuitry as suggested to Santos and MLLoydl. Alan I don’t think the problem is with the transistors.
These are of the lateral type construction. THese are my favorites: Phil Burning is typical unstable Circuit. Two pairs were used per channel.

Have you 2sk15299 a voltmeter acros the bias network or from gate of J to gate of K and tracked that voltage with time? Really lots of thanks here. I am not sure, but I think they use the same die design for some of their devices as the orginal Hitachi parts. Gate threshold voltage Vgs th.
Amp fixing groman Thanks for the advice – akltam And they will be usable if not better alternative! Groman had a real good point about the bias voltage. Thanks for the advice – J.
Alan djk is right! Produst description The Field-Effect Transistor FET is a transistor that uses an electric field to control the shape and hence the conductivity of dayasheet channel of one type of charge carrier in a semiconductor material. NT – akltam Does anyone has such experience with SJ and SK I leave it on for a while feeling OK. Go to this site: Also the quality of these BUZ? I had a similar problem a month ago and it drove me crazy.
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!

Thermal Runaway posted by djk on January 06, at And the Sj have it at mA. I rebuild the whole thing and this time I used around 50ma per pair, i. The gate resistor is ohm already. Also good for outputs for amps in the 25W size. I have built similar power amps with the same circuit with SJ but with satisfactory results. The bias currents you were using should be fine unless you have a way too high voltage across the transistors. Check for high frquency oscillations MHz range.
Any experience on 2SJ and 2SK? Burning is typical unstable Circuit. After another hour, it was overheated and destroyed.
