I'd start with a PV Optocoupler like the PVI5050 and just hook the
output to the gate and either the source or drain (as appropriate) of a
suitable power mosfet - that's pretty much it.

Note or a link,of a Solid-state relay which could be used in a 120VDC-10 A application?I have in mind a SSR employing N-channel MOSFETs (IRF740), but I would liketo compare its performance with some other diagrams before really implementing it on the final design (not a commercial one...) Thanks so much in advance, Gustavo Aguayo
