    Hello,

    I would like to experiment with N-Channel enhancement MOSFETS.

    Which part # EMOSFET should I purchase that comes close to the MOSFET described at 12:30 of the following video:

    http://www.youtube.com/watch?v=NSD7n7CR5cM&feature=channel&list=UL

    There are so many out there that I don't know which one to start with!

    Here are some details:

    Name: Enhancement Mosfet
    Channel type: N channel (built by minority carriers)
    Max source voltage: 6 to 10 VDC
    Max drain current: 50 ma
    Threshold voltage: Approx: 1V
    Package type: TO92

    Any suggestions would be very appreciated!

    I personally like the 2N7000, as these have a higher current capability, but either should work...

    Hi tshuck,

    I would like to ask you a question.

    There is a mosfet called "Depletion/Enhancement Mosfet" which can be used in two modes either depletion or enhancement.

    However there is another type of mosfet called "Enhancement mosfet" which is the one I am looking for and shown at 12:30 of the following video:

    http://www.youtube.com/watch?v=NSD7n...hannel&list=UL

    This type of mosfet simply accepts positive threshold voltage at the gate which allows an N-channel to be formed by minority carriers connecting the drain to the source. The higher the gate voltage above the Voltage threshold, the more minority carriers form creating a bigger N channel thus allowing more current through drain/source. Is this exactly what the 2N7000 part does?

    thank you so must for your help !
