How does a rectifier diode differ from a communication diode? Can they be used interchangeably?

A power rectifier is designed to have a fairly large junction area to handle larger amounts of current. As a result, its junction capacitance is quite a bit higher that of a smaller 'signal' diode and it would allow a lot of leakage in low signal level, high-frequency circuits. Conversly, most signal diodes have maximum forward current ratings of a few tens of milliamps at most so they couldn't handle the usual 'amp and up' currents that power rectifiers are required to conduct.

TThe 1200V ones might desire to do the interest, in the event that they are bodily the comparable. purely might desire to be certain that the switching situations are the comparable or extra effective additionally, yet i think that purely isn't a concern in regular mains frequency generator basically reason i'm able to think of of is that the decrease voltage ones may well be the extra low priced ones, and that stands out as the unique producer selection.
