“H”
are heat sink mounting,for example URB2405D-30WHR2 is with heatsink, URB2405D-30WR2 is without heat sink.
If the application has a higher requirement for heat dissipation, you can choose modules with heat sink.
②.
Absolute maximum rating without damage on the converter,but it isn't recommended.
③.
For dual output converter, the given value is the same for each output.
