    Hello all:

    Does anyone know about some reference material on resistance of a pn junction? I recently learned in my class about a p-n junction's use as both a diode and a resistance. I think I understand the diode fairly well now. However, would like to do more study on the "resistor" characteristics of the p-n junction. I didn't find anything on it in the "All About Circuits Vol. III Semiconductors" section of this site either.

    Thanks a lot!

    You can google p-n junction diode for further info........... there is a forward volt drop of 0.7 Volts in forward bias (in case of silicon diode), apart from that a diode will just act as a semiconductor resistor and dissipate heat.
