dougp:
The voltage drop depends on the material (silicon vs. germanium), doping, temperature...
"The electrons must be pushed by a voltage with enough force to cross the p-n junction, and this push is the source of the diode forward voltage, or forward bias voltage drop."
So if I'm reading this right, the forward voltage (in my case ~2V) will be generated automatically by the p-n junction when any kind of current starts flowing, and it will stay at 2V regardless of if the input voltage is 5V, 12V, or 1,000V?
