shevekI'm looking for a MOSFET, and I have no idea what is a reasonable power dissipation if I want to mount it without a cooling fin.  From R_{DS}(on) and the I_D for my application, I can compute the power (R*I*I), but I don't know what is high and what is low.  I now have one that would dissipate 500mW.  Is that good or bad?  What should I aim for?10:18
DocScrutinizer05aim for one digit milliOhm Ron12:50
DocScrutinizer05500mW sounds a lot, except for when your app is 2lW or more12:51
DocScrutinizer05without cooling measures you want <<100mW13:00
DocScrutinizer05a proper PCB goundplane is ok for maybe 100 to 250mW13:01
