2SJ74 & 2SK214 Hitachi laterals

gaborbela · 31st August 2009, 04:50 AM

Hello
I have 9 matched pair of these lateral mosfets . My question did someone ever use them as output power mosfet .I know is has a small W-rating but if we double or triple them I think possible to build some 50W amplifier out of them .
I like the quality of these mosfets , I would like to use them !
If someone know any simple schematics using these laterals please help me with these . Thank you
These mosfets cost me to much just to keep them in the box .
Thanks
Greetings

gaborbela,
What is the calculated Imax?

Hello
I think something 10mA for class A/B .
Or 06-08A for Class A around 8W .
I do not find any information someone ever try these laterals as a power output but they are really great sounding mosfets .

gaborbela,
sorry for the loosely formulated question. Anyway, considering that Rdson is 8-10 Ohm, (Crss 2-5 pF), I would abandon the idea of paralleling.
No problem using 2SJ77-78-79 instead of 2SJ76.
