[SOC] Re: Big Time Technical Question

[Jim]

The biggest advantages of Schottky diodes are 1) their
low forward loss (can be under 0.1 volts as compared
with 0.6 volts for silicon diodes) and 2) their fast
switching time.

They are used a lot in VHF or UHF applications where
the switching time is important. For example, a
transverter where you're trying to preserve something
like the full breaking the HF rig has would probably
use Schottky diodes for switching.

They can also be used in things like RF probes where
their low forward loss makes them more accurate and
usable to lower voltages.

Their biggest weaknesses are 1) they can't handle huge
reverse voltages (typically under 100 volts reverse
breakdown voltage) and 2) they are more susceptible to
damage by heat.
