Not necessarily.  I haven't used a diode for reverse protection since
Russell turned me on the the reverse PMOSFET method.  I prefer it
greatly because it doesn't require such a high drop as the diode
method.  I don't know if there are any disadvantages; it seems to be
pretty sturdy to me.  It is a bit pricier, so in 10000 uber-cheap devices,
it's probably not worth it, but in a higher quality device where an extra
$0.10-$0.25 per unit won't make much difference, it's pretty appealing.
