Yes, there is a V/I curve for diodes. Look at the datasheet. it is not linear.Generally what I see on 'spec' sheets for voltage drop is: "max 1 volt@1 amp".
In my circuit running at 1.2vdc, 50ma, I measure a votage drop of about 0.2v. Is this correct? Does voltage drop change with current?
According to this from the attached datasheet; forward voltage would typically be 0.6V @ 10mA and 0.75V @ 100mA.I looked at some data sheets and voltage drop seems to be about 0.6v @ 100ma. Would a measured voltage drop of 0.2v be reasonable for say 10ma?
No, that is not reasonable at all.Thanks GopherT. I'll try to find a data sheet. (when I said 'spec sheets' I meant the data that is listed on a site like digikey)
