humm.. 10v for switching. Will this work? took from other topic: http://arduino.cc/forum/index.php?topic=75747.0(need to learn about mosfets...i think it will took a year).
I found this FET. http://www.datasheetcatalog.org/datasheet/irf/irlz44n.pdfIt´s a logic level FET, so I think a "pre transistor" to achieve RDs(on) won´t be necessary. Am I right?
Thanks BillO , Grumpy Mike and DC42. My plan is to isolate these fets with an opto. I´ve bought some STP80NE06-10 and HUF75652G3 http://www.fairchildsemi.com/ds/HU/HUF75652G3.pdf. Ill study a bit more to conclude what suits my needs. I´ve learn a lot on this thread.And still have a lot to learn.
Whats the real current this FET supports? VGS of 10V is the maximum voltage gap between gate voltage and source voltage? As this FET has a RDS(on) of 5V , can I use on 28V? VGS is not clear to me yet.
Cross fingers or will this work?
