Lateral Mosfet Amplifers 250W - 2000W RMS Power Amplifier modules

[Class-D Design]

Hi Col,

Our plots are the original plots of the genuine Lateral Mosfet Amplifier, done on our own AP analyser. The others are not plots of that amplifiers shown.

I can't see any plots on the Aussie Amplifiers site.

i saw it , it is/was the same, but still no tim/imd

we are now manufacturing a new updated batch ready end of september will send you tim/imd then

Is an updated & informative datasheet available for these lateral mosfets? I would be interested in seeing it as I'm interested in buying some of these - could somebody email it to me?

Are the class-d lateral mosfets designed to operate cooler than the 2SK1058 and 2SJ162? Currently an amplifier project for home theater is being built using the listed devices. Heatsink area is a concern for the number of amps to be incorporated into the case. Feedback would be appreciated.

If they have lower on resistance than the Hitachis (which is possible as 12A max current is suggested) then you will get a little bit more output power for the same rail voltages.

The power dissipation will not change much though as a class AB amplifier playing music spends most of its time at low output power. Idle current, rail voltage and load impedance is what matters.

The "data sheet" provided is very inconcistent though. How does 150 degree Tj max, 125W Pd max and 1.6 degree/watt Rthj-c add up?

Avnet has a good price on the Hitachis.

I tried AVnet & as somebody here cleverly said it should be called "Havenot".

My experience wasn't good with them - I think the consensus is that unless you are a large company they don't want to know.

I ordered 10 2SK1058s but because my delivery address was different to my billing address I got an email to confirm that I was not selling these on. Fair enough - I answered it. No reply for 8 days after a lot of emails to them to find out what the status on the order was.

They also added an extra $20 onto my order that I was not aware of at time of order & only spotted when I reread their only email to me. I finally cancelled my order & queried the $20. They quickly replied to my cancellation, thanking me (as if they were glad of it) & said that the $20 was for if shipping charges were more than anticipated!

Seems very unprofessional to me!

Edit: I agree with the opinion on ClassD though - I have asked them for a proper datasheet on their mosfets but got none. In another thread a user of these mosfets replied that they were good - more powerful than the 2SK1058 but not as sweet.

How similar are these Class-D brand FETs to Magnatec BUZ901P/BUZ906P?

Are they the same? Similar in any way? Bigger die?

Update: I was contacted by Class-D & they are sending me over some Mosfets to "play with". Good response from them, I reckon.

Had a good chat with Mike from Class-D (he's the amplifier man there) & he struck me as a knowledgeable & friendly guy. They have some interesting products being launched between now & christmas but I won't steal their thunder. One thing he did say which I can tell is that they have removed the in-built zener from the mosfet to prevent oscillations.

Now I don't have much experience with laterals so I'll be comparing them sound-wise to some Fairchild FQA34N20 mosfets in a source follower Susan Parker Zeus amp. It will take a while though.
