optocoupler mosfet

hi,,how do i connect properly the optocoupler with IRF350 mosfets that would control an 8Amps, 220v Ac Motor??
my problem is i dont know how to properly connect the optocoupler to the gate of the IRF350 mosfet..

pls post any schematics that would help me...

thanks n advance...

Please refer the data sheet fot IRF350 attached.
The ratings will help you plan how to go about.
You are using AC motor.

i alreaady read the datasheet of that mosfet...if you have any circuit that would help my problem pls. post it..thank you..


i posted an atachement. pls. evaluate this circuit if you think this would possibly work before i may buy this components..just to be sure a little.

Hi Romel,
max Vo of 6N137 is 7V acc to datasheet. You should use an IPM type optocoupelr, where Vo can be up to 20V or 30V. Check, for example, ACPL-P456 or HCPL-4506.

I should look your circuitry again in detail for further points.

Cheers
