Without trying to be difficult (trust me, I don't have to try very hard ;-) ) If you have a diode passing a large current it will get hot. Wouldn't this thermal energy be from the "in" current, so the "out" will be lower than the "in" ? I understand some junction electro-chemistry, but not that much. Surely a diode is not a perfect conductor -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
