    Hi - I was wondering - with the vast sea of mosfets available out there -
    are there any that stand out as being the most useful, the most used, or
    the most important? Thanks alot as always,

    Michael
     

  2. The 2N7000 (TO92) and 2N7002 (SOT23) are devices that probably fit your
    description.

    Their prime advantages include widespread availability at very low cost and
    very low capacitances for very high switching speeds with very weak drivers
    (simple CMOS logic gates can drive them at several megahertz without much
    difficulty). They also feature adequate voltage and current capability for
    most low power devices.

    For higher power devices I don't think there are any clearly classic
    devices, but the IRF510, IRF520, IRF610, and IRF620 are all quite common
    parts as well. Those devices are made by several manufacturers, not just
    International Rectifier. All of those devices are fairly wimpy and somewhat
    obsolete though by todays standards.
