The bridge rectifier is generic, pretty much anyone that will fit (or can be made to fit) will do. The IC is a STR3A153D. No one seems to stock these (at least that I found in a few minutes or googling).
There are several similar parts in the STR3A1xx series that differ only in rated output power and Rds. STR3A151D = 24W, STR3A152D = 30W, STR3A153D = 36W, STR3A154D = 40W, STR3A155D = 43W. The pinout/package is the same for all variants.
Obviously if you can find it order the correct one, but if I found any of the others in my junk pile I wouldn't hesitate to try them.
