If a DIODE or RECTIFIER can handle 1000V and 75Amps is it also safe to run the same diode at 20V and 300Amps.?
The first is 75000Watts and the second is only 6000Watts in theory it should work..?
The diode will blow up.
You can't multiply voltage and current ratings together and get anything meaningful. They are different ratings and mean different things.
