I've read the claim that diodes drop 60mV per current decade. I measured shottkys, standard silicon diodes, and b/e junctions. By my testing ONLY THE SHOTTKYs follow the 60mV rule. MBR3035PT: 59.3 mV 1N5818: 60.4 mV Ordinary silicon diodes 1N4148: 119 mV 1N4003: 102 mV I tested the b/e junctions of half a dozen different kinds of TO-92 pnp transistors, and all measure around 75 mV per decade, give or take a few millivolts.
