Parts data Sheet

I have 2 components and I would like a data sheet for them to know what they are as the distributor is dead.
They are out of a Mallory Distributor.
The part numbers are

G4BC404 or ( IR624P or 1R624P It is hard to make out wether it is a 1 or I ) I am not shore which number is the correct part number for this component

Next component N520AB or 30N6S2D I am not shore which is the correct part number.

The numbers above is what is stamped on the component

I live on the North shore of the United States. I don't know what that has to with with electronics. Maybe down under, that is the way "sure" is spelled.

The 30N6S2D appears to be an IGBT: https://www.alldatasheet.com/datasheet-pdf/pdf/51705/FAIRCHILD/FGB30N6S2D.html

Try alldatasheet.com for the others. A little more information about the devices, such as packaging or pictures would help.
