In the beginning I intended to use it instead of building the rectifier circuit, but after I had a look over the the datasheet, I really got confused.
It is written in datasheet something about half wave.(does this mean it is half wave rectifier ?then how it produces pure DC ?)
Also I thought that it may have internal capacitor to reduce ripple.
Another weird thing, that I have read in the beginning of datasheet:
"Voltage range 50 to 1000 volts"
Why does it have a minimum range? I was intending to use it to rectify an AC 6 volts. Does this mean that it will not work?
It comes in several versions with MAXIMUM ratings of 50V to 1000V. Any of them will work fine at 6V. It is a full wave bridge rectifier. References to half wave or half cycles are simply for the purposes or specifications and ratings. You need to add a smoothing capacitor to get pure DC from it and even then you will have ripple if you don't use a regulator.
