Where 80,286 fits
Why 80,286 is special
Protected mode let the processor stop one program from reading or corrupting another's memory. The 286 could enter it but not cleanly leave it, so early software largely ignored the feature — a design gap the 386 fixed and the reason the 286 is remembered as a transitional chip.

The 286 introduced protected mode, which stops one program corrupting another's memory, but could not cleanly return to real mode once in it. Software largely ignored the feature as a result, and the 386 fixed the gap — which is why the 286 is remembered as transitional.
