Body

Hi Mick,

MOSFETs conduct in both directions when turned on. But because of the intrinsic parasitic diode in parallel with the drain source channel they're always conducting through that diode when it's forward biased. Putting two MOSFETs back to back will make them work as an AC switch. Connect the sources together and the gates together and the drains will conduct in both directions while one of the diodes will always block when the MOSFETs are in the off state.

Regards
Ole

 Kone, 

 At one point when I asked about disecting the SSR you said something about Mosfets working in only one direction.
 

 Did you mean that they can source bidirectionally but only sink one polarity?
