hello;
my question is on optocoupler (fairchild semi mocd207m) is, on the fairchild datasheet for this device, states that the forward voltage drop is 1.25 with a max of 1.55. however, the min is just a dash line.
i'm using a dmm, which is set to diode and I'm getting 1.03. and when i check the reverse i'm getting .701. i believe that i have a bad opto. the reason why is, when checking the forward voltage drop i should not be below 1.25 and when checking reverse, i should see an open.
is my logic correct?
also, should i be calucating for the min? if so, do i just subtract the max from the nomial to get the min?
thanks;
