Thanks Lefty.When I search a company like Mouser or Digi Key for a logic level mosfet, what filter am I looking for?
Doesn't look like that particular table's any use. Farnell do a better job with the Vgs value for Rds(on) being one of the search
terms. However don't get me started on their system, so many ways their search could be improved!!
Some manufacturers include an "L" in the part number if its logic level, but you have to know their
particular naming conventions to be sure. ST microelectronics and International Rectifier both seem
to use this convention.
Generally a FET is more likely to be logic level if its in a surface mount package, so TO220 and so forth
are mainly 10V devices, but its only a general trend. Some surface mount packages like DPAK aren't
particularly small and can be soldered onto strip board fairly easily, note.
