Is anyone familiar with using diodes for more general

of rupture current with respect to normal use maximum
as of course never in the data sheets ?

The entire purpose of fuses is to have something guaranteed to fail in a
certain way. Diodes are not guaranteed to fail one way or the other and I can
only tell you that it's not a great idea to use a diode as a fuse.
