SB = Shottky barrier. Techy speak for 'shottky'.

Not to get too bogged down in terminology, but
sb = schottky barrier = schottky ?

Yes. The barrier bit is optional if you like. It's about the junction inside the
device. Like pn junctions. Except this one is a barrier. If one cares to be
verbose, ordinary silicon diodes could be called junction diodes.
