    How breakdown voltage of common base configuration is higher than that of common emitter configuration??

    in common base, break down is more or less similar to PN junction breakdown.
    please explain how breakdown occurs in common emitter configuration???
    I read because of transistor amplification, common emitter Breakdown has less value than PN junction breakdown. more explanation needed to understand clearly.

    Either I do not understand your question or your belief is false. Please make a drawing and use arrows to show the direction of breakdown which you are questioning.

    Here are some symbols to work with. They are opened with MS Paint.
