Just to clarify, this MOSFET (FH012AA) is not a recommended part from Ducati. I cottoned on to it after reading many different pages and posts at various different forums (Honda, Aprillia, Triumph and others) discussing swapping out the factory or standard SCR (shunt or series) type R/R for this or another MOSFET unit.
I replaced my original R/R with this particular unit because of its specifications as it adequately met the requirements necessary for my '97 model 748 (i.e. 14.5V and 40 to 50 amps whereas the original unit output was 35 amps). At this time I shouldn't expect info will come up if you search for it as a Ducati sanctioned replacement part because as far as I know it's not.
As a bit of a head start I included links to some relevant pages for those who'd like to know a little more before deciding either way on this as an option. It's clear that Yamaha have been using the 012 for some time now and perhaps other manufacturers are also switching to MOSFET type R/Rs simply because they are a more robust technology.
As for which particular mosfet unit would be most suited to other model Ducs you'd need to check the specs for the original Ducati unit on your bike and cross reference those with the specifications for each of the Shindengen MOSFET units. I know they make several different units however I have not done the research to marry them up. Chances are though that this FH012AA unit will perhaps even better serve more recent models since it is originally designed for a three phase system, not single phase like my bike but it does the job despite this.
Perhaps later model Ducs probably don't suffer as many R/R meltdowns as this era does so replacing the stock unit may be redundant although I do recall reading somewhere I think that some of the 1000's where the R/R was mounted under the seat were prone to overheating.
Perhaps other members out there, if they do identify a suitable mosfet unit for their model, will post the info to expand the relevance of this article to other Ducati models.
SE84.... thanks for that link, it appears there's a MOSFET unit available for some model/s Ducatis, but from that page I can't identify which. Perhaps Ducati are now using them. I note the unit is a FH012CA rather than AA.
What model Duc does this unit suit?.
