I spotted something while sifting mosfet datasheets, and what I am seeing in the graphs for
safe operating area suggest that some mosfets are only for smps/pwm. All the lines are dotted,
and everything refers to speed, or pulse width, microseconds. Does this mean these devices are not okay for
turning on a load full on, sans pwm or whatever? For other mosfets, there is a solid line in
the graph, showing non-switched operating area, like turning on a light bulb, or something
like that, as well as the dotted lines for different currents and pulse widths, usually higher.
