Not very informative data sheets anyway...

It seems amusing that the photos of the Semelab Mosfet packages on the Magnatec websitehave the part number used by Class D
Class-D Design Ltd.
According to Semelab these parts are 8 amps per die.
Class D rate their mosfets at 12A per die!
As far as I know, these parts are not exactly the same as the Magnatec BUZ / Exicon Mosfets. They have made some minor changes to the die construction.
I would be very interested to know if anyone has managed to construct a high power amplifier, Say 500w RMS 4 Ohm +, using multiple semelab lateral mosfet output stages, that was reliable, and did not suffer from component failure.

I must say that my first thought seeing site and picture of devices was "cheap looks, and what a strange name"

Oh btw, I just recently did take a look at some BUZ devices, and I thought that 30 EUR was way too expencive

Interesting choice for a name. From Wikipedia:

An alfet (Old English: ālfæt, "fire vat") was an ancient cauldron filled with boiling water, into which an accused person was to plunge his arm up to his elbow. If hurt, he was held guilty; if not, acquitted.

Hi,
but for that price would it be too much to ask for data sheet and some documentation on the cauldron technology?

You will find the subjective effects far outweigh any objective, measured benefits......

Hugh,
some information could tell something about the direction of development. As a matter of fact, I`m curious.

Are these the special Magnatec AnthonyHolton advertised intensively about while working with Class-D Design
And suddenly had to do without, after the split

I think these are the self same mosfets.
As for Mr Holtons opinion on them, all I can say is Ask him!
If you click on the component name hyperlink you get a reasonable spec sheet

Xoc1,
you call that a reasonable spec sheet?

Point taken - No actual performance graphs

 

[Jon Lord]

For those mislead by this thread:

The linked datasheet features performance graphs (now) and it looks IMO very reasonable.

Btw.: The Exicon MOSFETs were always from the same source as the BUZ9 and AlFETs (At least the Silicon always came from Semefab).

I see that Class-D actually claims that these mosfets are THEIR product.... and another company called Proaudio Ltd also claims them as theirs.... but "curiously" stocks the same product range as Class-D

Beaware of Thugs.

A guy called Mike soppelsa from UK is behind all this, some people from Tasmania already felt the heat.

URL is dead. The so called AlFet (replacement for the older EXICON's) from Magnatec/Semelab obviously no longer available.
Are there successors ? Maybe this one ? go to

No TO-3 outline, only TO247.
