Probably classified, though it's going to depend on what you're trying to do with it (technically, you can get a criticality without any explosives, it just disassembles itself before producing much of an explosion).

The problem with using it for a super tiny fusion weapon is that the explosive product is 2.5 MeV gamma rays, which will not be efficiently absorbed by a compact fusion target (this also limits the minimum practical size, as you need to wrap it in enough shielding to efficiently absorb gamma; a couple centimeters of lead is adequate. Of course, if you're just interested in destroying electronics, just expose it directly, you can wipe electronics with much less radiation than it takes to melt or vaporize the chips).
