My post of yesterday never showed up. Here it is again:

The MOS Drivers are made of opto-isolated PV cells
internally wired in series. These allow you to DIRECTLY
turn on and off any power MOSFET through an isolated
I/O.

My favorite is Toshiba's TLP191B. With 2500v RMS of
isolation, the device, 1/4 the size of a 4N26, can deliver
over 20VDC with 5V applied tio the input thru a 330 ohm
resistor. While its spec says "min 7VDC" of output, it actually
delivers quite a bit more; I needed a 220K load resistor to
speed up on/off times and to prevent overdriving my power
FETs.
