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.
60mV per decade?

Ah you must be a mathematician :-)
The difference between a mathematician and an engineer. An engineer and a mathematician are put in a room. At the other end of the room is a beautiful naked woman. They are told that every time a bell is rung they may move half the distance to the woman. The mathematician: I'll never get there.
The engineer: I'll get near enough. Start ringing.
